277volts AC line I need to find the breaker

What basic, single and reinforced insulation?

I have a feeling it's international.


Perhaps the resistance drops when it's overvoltaged so you're passing more than 320:mu:A.

It starts from 0,6kV or 0,75kV, then its 1k5V ~ 3kV. Depends on the application. (Later I'll do a research on this).

Well, the original resistor I don't know the insulation class, because the cheapo screw drivers I've bought are all Made in China (Bloody chinese products, lol). But they look like a piece of charcoal.

I've always been concerned about unsafe Chinese products leaking accross our borders. I think with something safety criticle like this is worth paying extra money for.

Yes, that's true.
