Re: Improbable
Yeah, had to do that to prevent a meaty arc welder consuming 13 A fuses. (Bit 'o fuse wire soldered across the 13 A fuse to give it a bit more "delay".)
Worked fine until the welder developed a shorted turn. Took out the 30 A fuse for the ring in the main fuseboard rather than the one in the plug.
Remember, there's (almost) always something meater further upstream ... £30 A in the consumer unit, 80A or 100 A main service, 400A in the substation ...
As my first governor used to say "So it steams a bit."
Reminds me of back in those days in a test gear department ... One of the Test Room boys brought in a bit of kit that "didn't work". I whipped off the plug cover to discover that one of his coworkers had replaced the fuse with a 1 inch length of pot spindle - nylon pot spindle.
