We have an e-waste here at our school. Today I found about 20 12A variacs that all have "broken" written on them. Well, whoever wrote that must not know the difference between "broken" and "blown fuse" because they all work once the fuses were replaced. (I'm guessing that's the reason why there were so many of them.)
I'm going to take one or two home for various projects. I also use them here at work so I'll keep a few to replace the 10A versions we use.
Yes, before I plugged them in I tested for continuity between any live wire and the shell of the variac, and also to ground. They all checked out.
Anything else I should do with them?
