    Sparky's Magic Fusebox

    This is a genuine question, as I do typing rather than wires, but is it normal for something that happens in the kitchen to trip the whole building?

    Even here in Spain with their dodgy electrics, all I ever need to do is reset the fuse switch for the one room/zone which has the problem.

          Morphy Richards! There's a brand I learned to really hate

          My mum had a Morphy Richards iron which broke down at regular intervals,

          Because I finished junior school early on Wednesdays, the lot of taking it to the repair centre fell on me.

          So on top of a half hour bus ride home, I got another half hour's bus ride taking the bloody thing to the repair centre, and then another half hour's bus ride home. When they deigned to fix it, the same to pick it up again.

          On one occasion I had to visit the dentist for some fillings on the way home, then pick up the iron and take it to the repair centre. 2 buses to reach the dentist, a further 2 home, then then dreaded 2 to the repair centre and back, the last 4 with a numb gob.

          I have avoided buying anything from Morphy Richards ever since.

      If you get overload on one of the circuits then the MCB will trip but it needs a very big overload to trigger it.

      However each you will also usually have an RCD which will trip the whole CU if it detects an earthing fault or you decide to test if a wire is live with your tongue.

      You could also have RCBOs, ELCBs, MCCBs etc in that equation as well.

      It depends on the standard of wiring. Most of mainland Europe is point to point wiring, the UK uses the ring main system, but some ring mains are not well implemented.

      With point to point and the upstream RCD having a higher trip current than the downstream ones, an earth fault at the end of the chain should not trip the second level RCD. But if there is enough capacitance and inductance in the wiring, an earth trip may cause a spike which takes out the higher level rcd. This can especially happen if there is a lot of electronics on a ring main, because the X and Y capacitors of the spike protectors all add up, and while the lower level trip is opening they may cause an arc which is big enough to trip the the higher level one.

      You used to get the same effect with incandescent bulbs blowing at the end of a long wire and, despite there being no earth leakage as such, the inductive energy in the loop was enough to trip an RCD.

        With point to point and the upstream RCD having a higher trip current than the downstream ones,

        The codes I know don't allow cascaded RCD's; it's either an RCD with a group of plain circuit breakers downstream (here in .nl it's four maximum, ISTR it used to be six), or a combi RCD/CB per circuit.

        1. Martin an gof Silver badge

          Re: Sparky's Magic Fusebox

          The codes I know don't allow cascaded RCD's

          In the UK there are a very few specific circumstances where cascaded RCDs are allowed. Specifically the main case would be where the installation earth is from an earth electrode (e.g. a rod) because the impedance of live-earth is then too high to blow a fuse or trip an ordinary MCB. In a typical domestic installation, rod impedance to earth might be as high as 200 Ohms, which at 230V is only about 1A - obviously not enough to trip even a 6A MCB.

          However, it's no good "the upstream RCD having a higher trip current than the downstream ones" because in the vast majority of fault conditions, the fault current will be higher than both ratings. RCDs used on sockets are usually 30mA while upstream RCDs which are used when earth rods are present are 100mA. Either, or both (yes, I have seen that several times) will trip under even fairly normal fault (to earth) conditions.

          In the UK, if such an installation is unavoidable, the upstream RCD must be time-delayed. It's a few years since I was a registered sparky, but 100ms comes to mind. This is to allow the downstream RCD time to operate first. 30mA RCDs for the preservation of life (which is what these are) must trip within 50ms (again, IIRC) for a 1x rated current fault.

          The 100mA unit isn't there to preserve life (100mA for 100ms may kill you), it is there to remove mains voltage from the earth wire and anything else (metal pipes for example) connected.

          Of course, many domestic users will also have "portable" RCDs on their lawn mowers or hedge trimmers or whathaveyou, and these will have the exact same rating as the installed ones, so it then becomes a race between the 30mA RCD on the extension lead and the 30mA RCD protecting the sockets circuit.

          The best installation method is to avoid cascaded RCDs at all, and if the earth can be upgraded to a TN system (earth from the supply side) you can get rid of the rod and the 100mA unit. RCDs on each individual circuit is the ideal situation, but when an RCBO (combined RCD and MCB) from a cheap brand costs perhaps £20 while a bare MCB is only £3.50 (more expensive types here and here), there's an economic calculation to be done, especially in larger houses which may have a dozen or more circuits.

      Re: Sparky's Magic Fusebox

      Shortcuts where the resistance across the shortcut is _very_ low tend to trigger not only the fuse on the branch but also the main fuse. Prime examples are water boilers and, indeed, toasters.

      Modern installations with faster fuses can mitigate this, but may trigger unnecessary when set to "very sensitive". I have seen one that would trigger upon touch of the glass of a light bulb, go figure.

      Putting the IT on its own "main" rail makes a lot of sense.

      In the UK, they moved our office around, facilities moved my floor-box a couple of meters and plugged it back in, I then plugged in my PC and BANG! They had rotated the box 90° and Pos, Neg and Earth had moved around, the PSU didn't take well to that!

      Here, in Germany, the sockets are sunken into the wall and the Earth is exposed. Great for getting rid of static.

      But in my office, the trunking is a waist height, which is very useful. One day, I lost my balance and reached out and grabbed at the wall, managing to stick fingers in a socket to save me and, BAM! I got a shock right up my arm and my shoulder was killing me.

      I went to our technical department and they laughed and said, not possible. I insisted, that my arm hurt and that I had received a belt from the Earth connector. They came out and tested, it was live! The electrician, who had wired up the building over a decade earlier, had managed to swap earth and positive on that one plug!

      Not in a major office, but common in a home or small office. Toasters will even do it with build up of carbonising crumbs, don't forget to empty the crumb tray or shake it upside down.

      A L-N short will just knock the individual trip, but an L-N imbalance of less than 50mA (due to leakage to case / earth) will trip the main safety trip. Some countries the lighting isn't on it. Usually Cooker, Immersion/water heater etc isn't on it. So a toaster with a shorted filament / Kettle shorted element on a socket wired on cooker supply (used to be common in UK) will hit the cooker fuse or trip only.

      "

      Yes. Older buildings had each circuit protected with their own current breaker (or fuses in really old boards), but with only the main breaker having been upgraded to a "modern" RCB. Therefore an earth leakage fault would trip that one and only RCB but not any other breaker, thus cutting power to the whole building.

        > My indoor TV aerial took some cunning positioning

        I have a friend that lives at a fairly low level near the sea, and his TV signal comes from a transmitter somewhere past across the bay. His signal strength varies with the tides, because of multipath effects between the direct signal, and the reflected signal off the water - with the path length varying with tide state. I suspect it would also depend on sea state - with a flat calm surface being a good reflector, and a rough sea being a bad one.

        My grandmother used to live ina valley, relying on the TV signal diffracting over the hill, and reflecting off the cliff opposite (High Tor, Matlock Bath). She loved watching the snooker - even with 3 to 6 sets of balls on the 3 to 6 tables, there was a lot of ghosting !

He had neglected to remove the cellophane wrapper off the cheap "flying bomb" style batteries he had purchased from the local tat shop.

    So, as the queue built up behind him I very publically decreed that I was not responsible for his inability to install batteries and then charged him £15 for the privilege of ripping off the layer of insulation.

    This is one I didn't get blamed for, but possibly should have.

    Back in the day I was Head of Engineering (for want of a title) for a national broadcast radio network. I planned studio layouts, tech spec, etc and supervised construction and installation. I specified that the studios and news booths would have a panel at the end of the mixing desks to allow the connection of (theoretically obsolete) reel-reel machines. Each panel had two XLR connectors and an IEC socket for the mains. Simple stuff, although there was a rush on at the end of the install to get everything ready for our on-air launch.

    About nine months after we went on air, I was in the main recording studio, chatting to the recording engineer who was leaning with his back to the desk and both hands on the edge. Suddenly he screamed and leaped into the air, which was very entertaining, if a little surprising.

    Recording studios are traditionally dimly-lit, so perhaps that was the reason we hadn't spotted that the installer had fitted a chassis-mounted mains PLUG instead of a socket. Three pointy pins in the perfect spot where someone could - and did - idly stick their fingers. Obviously I should have looked more closely before signing off. Oh how how we did titter!

    Toasters - The scourge of the workplace.

    Someone in our office once attempted to make cheese on toast by turning the toaster on it's side. Yes, really.......

    Discounting the various hideous hygiene issues of this, the user then left a toaster unattended to go the loo. The resulting smoky conflagration resulting in a full evac of a 600+ staff for 45 minutes until Barney McGrew and co could turn up to pump out the smoke and confirm that this man was, indeed, an idiot of the highest order.

    Why 45 minutes? Well that's simple, the fire alarm company had been in to service the system a few days prior and diverted the callout line to their head office for testing, instead of the Fire Brigade. They then forgot to swap it back afterwards.... So at least the incident flagged up that little treat up without anyone being hurt.

The circuits were linked to several large UPS systems, one UPS for each circuit except for the downstairs main building circuit, which had two.

      So there was a large break room upstairs, where there was a Very Big Coffee Machine. The nearest wall socket to where it originally was was a white bezel normal circuit socket. All is well. For whatever reason, the electricians who'd wired the building put at least one red socket into every room, including the break room. I was not present when that particular decision was made.

      It was a quickly made tradition that the first person in from [name of department redacted, someone at the company might read this and would _know_ what I'm on about] would turn on the coffee machine when they came in in the morning, as that department ran on coffee. They would then go to their desk and turn on their computers.

      So the company brought in more staff, and there was a re-org. Stuff moved around. New computers were added. One item which moved was the giant coffee machine. The nearest socket was now the red computer socket. And then IT (that would be me) started getting complaints that all the computers in a large part of upstairs would die at the same time every day. And would die again, repeatedly, throughout the day. Checks of the systems showed no problems other than those caused by unscheduled power-downs. After the third day I came in early to see what was going on. I saw the first guy in turn on the coffee machine and then go to his desk. Purely by chance I had a look, discovered exactly where the coffee machine was plugged in, and went downstairs and got an extension cord and plugged it into a white socket. No further problems. What was happening was that the coffee machine drew a Very Large Load, and if someone then did something like sending out a print job to a laser printer (one of the large floor model copier/printer things) which was also plugged into the computer circuit, the resulting demand would blow the circuit breaker, a minor fact that had NOT been reported to IT (me) but only if all the computers and printers and whatnot were already running.

      The solution was to not have the coffee machine on the circuit, and to upgrade both the circuit breaker and the UPS to handle heavier loads.

      Yes, there was a write-up in the employee handbook warning people to not plug anything into the red wall sockets, but someone who really couldn't live without coffee and who couldn't be bothered to either leave the coffee machine where it had been in the first place or to get an extension cord knew better.

        Re: Coffee machines - Red Bezels

        On the grounds that life is not static, the company really should have fitted non-standard sockets for the red ones - MK make one where the earth and volts pins are rotated by 90 degrees on their own axes, so normal plugs just won't fit in the holes.

        Employee handbooks won't come between an early morning staff and their coffee - if something should be impossible, you make it impossible ;-)

    RAID5 failure blame

    Someone I know had done some IT work for a company, whilst there they notied the main RAID5 server had a failed drive, they mentioned this to the company but nothing was done, presumably because the management didn't see any failures because they could still access their files ok.

    As everyone here would've predicted, a few weeks later another drive died in the array, crashing everything.

    Apparently they didn't have a backup.

    Dumbasses.

    So guess who got the blame, and was steps away from being taken to court for something that wasn't their fault... thankfully it never even got that far, and I think the company had to pay through the nose for the data retrieval, all because they didn't listen to someone who knew what they were doing.

      Re: RAID5 failure blame

      This is why reports should always be as comprehensive as is reasonably possible and signed off by both parties whenever work is carried out. I recently did a fix where I noticed the power lead for a screen on the desk opposite was damage, the coloured wires being exposed. Mentioned it and they didn't seem to care. So I put in the report too to cover myself since it was a bit of kit that we might have on cover. That's apart from the "everyone is responsible for Health & Safety" mantra.. Same applies to dings and dents on the kit being serviced. They shouldn't have dings at all and any impact big enough to ding it might well be a contributory factor in failed HDDs etc.

      I've also had the "your engineer was here yesterday and now the printer doesn't work" story. Well, "yesterday" I fixed a bloody PC in the room next door. If you want the printer fixing book a chargeable call out. Of course it turned out that someone had accidentally adjusted the universal paper tray to US letter instead of A4 when re-filling it and according to others, the printer was working just fine long after I'd left "yesterday" from the room next door.

    We frequently used to get people plugging fan heaters into the "clean power" plugs

    ...despite them being bright red as opposed to white for "normal" power. Usually took out a quarter room approx 20 desks worth.

    You wonder what they do with the electrics at home........

      This is why there are slightly "non standard" mains plugs available, such as this or this, or others. Both the above are fully regulations compliant and can easily prevent most of this sort of problem.

          no, just cut the plug off, strip the cable ends and poke them into the non-standard socket. Simples. Cover with gaffer tape if you want to keep the elf'n'safety brigade off your back.

            Best of luck doing that with the Electrak - go on, take a look at the design and tell me you could do it without some kind of especially-made tool!

            I first met these when I worked in local radio. My boss, the engineering director, had specified Electrak for the roadshow truck because previous experience had taught him that while running a PA capable of filling a car park, a mixer, CD players and some lights from a 2.5kVA generator was feasible, also running the kettle that the DJs brought along was asking a bit much.

      Re: We frequently used to get people plugging fan heaters into the "clean power" plugs

      Ah yes, the fan heater incident ...

      We had one of those. The customer has a large unused (and officially empty) "upstairs" which at some point will become office space as they grow. The server room is also up there out of the way. When I fitted out said server room, I provided some sockets off the UPS in places convenient for powering stuff in the cabling rack - and labelled as something like "UPS maintained - IT equipment only".

      One day (a couple of years after this was all installed) we get an "angry" phone call demanding to know why we had installed such crap equipment as the UPS was beeping madly and it's all our fault for installing rubbish. I think many of us know the sort of phone call.

      I believe one of my colleagues remotely checked the UPS status and found it in overload bypass.

      After a bit of questioning, it was determined that a member of staff working upstairs (they use it for storage of their marketing stuff, I guess they were probably preparing some sort of mailout) was a bit cold, and seeing as there was only one socket at each end of the space, decided the sockets in the server room were more convenient - for the fan heater.

      Strangely, when they came to us with long list of gripes* at a meeting, this one wasn't made a big deal of it.

      * Many of them of the "why doesn't this work ?" "Well we've been suggesting for ${long period of time} that this part of your system isn't fit for purpose but you refuse pay for a new system" "It's still your fault".

    I was tasked with building a new computer lab for a school and the only thing I didn't have to do was get quotes for the furniture. Had the cabler and the sparkie in at the same time so they could sort any technical details that I may have not been familiar with and got them to send me a quote. Sparkie mentioned that the lab would need 2 circuits due to the number of machines drawing power.

    The Principal eventually got his ex teaching college friend to do the electrical and cabling work, much to my annoyance (I had previously seen his work). I was setting up the new machines ready to Ghost the image but when I plugged in computer number 22, the room along with several others went dark. My suspicion was that the idiot friend had skimped and only installed a single electrical circuit and it tripped the safety switch. Machines were imaged in 2 pushes instead of 1 and the fault was logged to be rectified. In the meantime I inadvertently was sent the invoice for the work done. Not only had they screwed up the power circuit but they charged $16,000 and change for the job when the quote that I had organised was just over $12,000.

    When it came to the fix of the power tripping once more than 21 machines were plugged in (not started, just plugged in), the Principal's friend just removed (or bypassed) the Safety Switch. Now if any of their treasured students stuck a fork or other related items into the wall socket they were dead. I had emailed this to the Principal and cc it to other appropriate staff members and interested parties (had to cover myself) but it was never fixed while I was there (left in disgust 4 months later). Don't you just love the duty of care catholic schools provide their little ones. I guess they were hoping anyone struck down in the lab would arise 3 days later.

      More likely they assumed that anyone struck down probably deserved it. God protects his own :-)

    Opposite way round

    I used to do network/IT stuff for a County Council as a contractor back when NetWare owned the market. Another outfit came in (mates of a Councillor, naturally) and promptly underbid me while ridiculing the Token Ring and 10-Base-2 systems in two of the offices. You can imagine the drill: "This guy put in fragile systems. Star wiring is the where it's at. He's ripping you off on call outs intentionally. He's an amateur" etc.

    Naturally I lost the contract and they refused to pay for about £5k of work. I wasn't feeling too charitable. Particularly since no-ever asked WHY I chose to stick with 10-Base-2.

    New guys come in one weekend, rip out all the coax, start putting in CAT5. Unfortunately someone tipped of the planning department. You can't go punching holes the size of coke cans through the walls of a Grade 1 listed building. That's why I had coax in there in the first place. Oops.

    Reminds me of an incident shortly after my grandparents moved in with us so we could look after them.

    With a routine that consisted of spending most of the afternoon asleep, my grandfather would always get up earlier than everyone else and make himself some toast for breakfast. It worked fine for several months, with only the occasional slice of burnt toast setting the smoke alarm off.

    Then one Sunday before six, he comes into my bedroom and shakes me awake to say "The toaster's not working". I try to turn the bedside light on but it doesn't work and I can hear my home server's UPS's alarm bleating too. "You can't use the toaster - we've got a power cut" I say to him. "Well, it was working fine a minute ago" he replies...

    I get up, get dressed and go and investigate the problem. Main breaker in the consumer unit has tripped so I reset it. I make sure everything is working properly again by making his breakfast for him. The kettle boils, the toaster toasts and nothing burns, trips, blows or fails. Next morning, I'm fast asleep and he shakes me awake again to say "The toaster's not working"...

    This went on for a few more days until I got fed up and decided to take the toaster apart to investigate the problem. Before upending the toaster, I emptied the crumb tray... and discovered that it's full of congealed butter! Which was not quite what I was expecting! I asked my grandfather why the crumb tray was full of butter but he said he didn't know. Anyway I cleaned up the mess and apart from the unexpected reservoir of butter, my inspection didn't reveal anything wrong with the toaster.

    Next morning I set my alarm earlier than usual so I could be in the kitchen to observe him as he made his breakfast. He put the bread in and turned the toaster on properly. So, so far so good. But then took a knife, carved a generous chunk of butter out of the butter dish, balanced it on the flat of the knife and held the knife over the toaster. Quicker than he can react, the knife heats up, the butter melts, slides off the knife and disappears down into the toaster. Now if the inadvertent insertion of a large lump of rapidly liquefying butter between the toaster's elements wasn't enough to trip the main breaker, then the fool chasing after it with a metal-handled knife certainly was...

    But why had the problem only just started after several months of successful toasting? Well, winter was coming and the kitchen had become much colder at night resulting in the butter in the dish no longer being in a spreadable state first thing in the morning. So he thought he'd worked out a clever way to make it warm enough to spread again!

    Normal toast production resumed after I bought him a tub of spreadable butter...

    A few years ago I was working in a secure Dutch lights-out datacenter. As far as I knew I was there only one in this huge place other than the security guard.

    All going well until after an hour or so the security guard ran in and marched me into a little room and proceeded to question me in Dutch. Not knowing Dutch this didn't go too well. Bad things were obviously happening due to the many phone-calls he was receiving. Within half an hour a posse had arrived to fix things.

    Cutting a long story short, it turns out that this secure establishment had suffered a rather large network outage causing untold critical infrastructure damage due to physical interference with their network. Scary! Luckily I was not to blame.

    I found out later that a local telco guy doing a job on the other side of said datacenter had plugged his laptop into the nearest patch panel to see if he could get Internet access. This was not the best thing to do on a secure site.

    I expect he was held in another small room for quite some time longer than I was. Never did find out what happened to him, but I was escorted 1:1 for the next two days while I did my piece.

    Bah!

    I once was almost the cause of a strike when I replaced a busted fuse in my supervisor's electric fire.

    She had requested someone from the electrician's department come and do the job, but no-one had moved since India crashed into Asia so I thought I'd do what was needed.

    The electrician who came by the next morning replaced my fuse with one of his own supply and promptly called his supervisor and union shop steward.

    I was called into the office and dressed down by my pointy haired boss (could have been used as the model for the Dilbert version, haircut and all) in front of the chief electrician, who then made a dreadful mistake by telling me that my actions were potentially dangerous because I wasn't a licensed electrician and more importantly, not in the electrician's union.

    I rose up to my full height, mentally said "goodbye job", then said "Don't lecture me on electrical safety. My father is a chartered electrical engineer and taught me how to properly fuse an appliance before I left school. If you care to look at the fuse you're electrician removed, you'll see I fused the device at three amperes, which is exactly the safe amount for that electric fire. The fuse he put in to replace my "unsafe" one was a 13 ampere fuse that stands a decent chance of allowing my supervisor to be killed and setting the factory on fire before it does its job."

    I was about to go on but my PHB grabbed me, pushed me out of his office in mid rant and sat down to placate the red-faced chief bodger. It was never mentioned again, and I kept my job.

    Many years ago I was flown out to Barcelona to install software at a huge Print exhibition. The hardware was supplied by our German distributers - new Compaq's

    The Spanish electricians managed to wire the stand with 440V - and nobody checked - every PSU blew when powered on. The Germans were able to fly in several replacement PSU's overnight - so the show did go on.

    A building I used to work in was regularly evacuated at around morning tea time. The fire brigade would turn up, clear the issue and allow us back into the building after about 30 minutes.

    After the 5th or 6th time, the alarm source was traced to one company's kitchen area.

    The smoke alarm was being triggered by the toaster. It turned out that one particular bread had a lower "smoke" point than all other. The user couldn't work out how to change the setting on the toaster to reduce the "browning" for this different bread. Sometimes the user was distracted and didn't "pop" the toaster before it got to the smoking stage.

    although only slightly related: my introduction to pro audio - in a brand-new recording studio. this 'way back when' their Ampex 2" 24 track recorder was the very latest 'state of the art' ... was asked to 'look at' a problem which was "the machine sometimes goes nuts & throws the tape around the room". as I'd never been near or even in such a facility... I arrived with concealed trepidation to find most of the boards pulled out & the maint guy quivering in a corner. questioning got "when the musicians come into the control room to listen back..." some hither-to unused common sense prompted me to pull the monster out & away from the wall to reveal the big AC plug. 'gosh' I thought... 'let's examine it'. ha - aha ! = most/all 3 'screws loose'. tighten, replace, start up... golden ! asked to be head of maintenance... accepted !!
