Why isn't my wine cooler powering on?

The only fuse marked on that diagram is the one for the motor, labelled TK. The parts marked JK and CR appear to be the start and run capacitors. There aren't on any of the circuit boards, so they are ...

400A PV Meter/Main as 200A

You said “ This means I'll be soaking up the ridiculous cost of a 400A meter/main to over come the 125% rule.” This rule is only for back-feeding an existing panel through a breaker and I think it is ...

20A and 50A receptacle on 30A circuit

Oddly, this same type of mismatch is pretty common for electric ranges. 40A ranges are installed with 40A breakers: yet there's no matching 40A plug. So the NEMA 14-50 is used for both 50A and 40A ...

Cable carrying capacity

In general, if a breaker trips due to load, the breaker size needs to be increased and the wire along with it. If the breaker that's tripping is a small room breaker in the panel, then an additional ...

Cable carrying capacity

Can I remove the pigtails on an AFCI breaker if I have a panel that supports plug-on-neutral?

The advice here is no different from "I have a wire I don't think I need. Should I just cut it off?" One would never cut off a wire in any case. Because first, you would need to terminate it ...

Can I remove the pigtails on an AFCI breaker if I have a panel that supports plug-on-neutral?

Pigtail breakers don't have contacts for PON panels, so you have to use the pigtail to connect neutral. Or return them and get the correct PON breakers for your panel. Always wire the neutral pigtail ...

Can I remove the pigtails on an AFCI breaker if I have a panel that supports plug-on-neutral?

NO! - it's very important to connect the pigtail to neutral bar where you removed the original neutral wire. The electricity needs a path back to neutral. If you only connected the white neutral wire ...
