Electric heat circuits

I agree. For example most water heaters would be fine with 12-2 if not 14-2 and a 20amp breaker. I think a lot of this is in place to protect against unqualified personnel.

No doubt that is true. The NEC has a lot of cushion built into it. It's why we have NEC calculated 800 amp services and the poco installs 100 kva transformers.

But that is also why we can get away with adding loads 99% of the time without needing to change the service.

I am not seeing the problem, this is an area the NEC works. It is not like AFCIs or mandated standby generator sizes.

I'm not against everything in the NEC, just most of it. :lol:

Protect them from what they don't know anyway:roll:

125 volts single phase service x 800 amps = 100,000 VA

What form number is the meter socket for that one?

I think thats it. If Joe DIY saw a 25amp breaker on #14 you can be that #14 will end up carrying 25 amps. :happyno:
