I hope I'm asking this in the correct forum. What is the latest panel installed you saw that used fuses?
I have heard that some have seen them installed as late as 1972, 200 amp panels with fuses. I was surprised.
Was there anything in code that would prevent them from being installed today, given the proper adapters were used?
I think the first fuse 'panel' I saw was a simple ceramic fuse holder for some abandoned K&T wiring. It had two fuse holders, that I assume fused the hot and neutral sides of a single circuit. It was surface mounted about 6-7 feet from the floor, all exposed.
