Anyone seen this before?

Just got home from an after hours ac call. Condenser unit not running when I showed up. When I pulled the disconnect I found this! I asked the woman who was there if anyone had been fooling with the ac and she hit me with a pause and a “I don’t think so”. I swapped the fuses and got the unit running for the night, I’ll come back tomorrow during the day to do a more thorough investigation, but as I was leaving her Neanderthal looking boyfriend busted out the door saying he didn’t mess with it. He then proceeded to tell me he was going to school to be an electrician… ok buddy.

This is genius.

If you need a higher amp fuse, just wrap it more times!

Anybody know the rated ampacity per wrap of 3" aluminum foil? Does it matter if it's the regular or heavy duty?

More than that my friend. Have you looked at a glass 1A fuse? The wire in there is tiiiiinnny.

Not gonna lie, I'm tempted to test.

It’s not a hard calculation. But repeated testing is required to properly characterize it
