Re: Not a PC
Respectfully mate, actually very dangerous.
Circuit breakers are meant to be inline with their load.
A 5A light shorts, the 30a fuse won't blow before the wires turn into white hot light.
The fuse on any circuit needs to be matched to the load. If the fuse is over rated it will simply not do its job and allow items down circuit to blow.
Eg: my house had the aircon on the light circuit (7.5A) and the lights on the aircon circuit (10A).
Aircon would trip all te time.
If the lights ever went bad, the chance of the wrong fuse doing its job is very low.
Very dangerous situation. I'm a 30 year old, 15m copper cable with too much load and the bite out of my cable from the rat 2 years ago will now cause arcing - didn't before because a fuse would trip before the arcing occurs, not now..
