Default Circuit Breaker Trip Amps

You mean the #14 it's wired with may be too small?

Why is it, in a boat or car, it's ok to fuse or breaker #16 wire at 30A on
a 12V DC circuit, but not on the AC circuit? That has never ceased to
amaze me.... They melt the same.

The electrons in an AC circuit are like a Chinese or Italian fire drill
compared the electrons in a DC circuit. They keep rushing back and
forth from one end to the other and generating a lot of extra heat.

DC circuits are like German fire drills. All the electrons are moving
in an orderly flow from one end to other so you can have about two or
three times as many participants.

Yep, that's it. That's my story and I'm sticking to it...
