Hello i have a situation where, im doing a penl upgrade. Its a 200 amp panel with a 225 amp bussbar.
I know 200 amp would be 2/0 covering 195 amps, but for the bussbar I would need 3/0 which covers 225 amps.
How do I choose the right size wire?
I know the nec table but then the 83 percent rule. I had an inspector speak to me about it, but still want to make sure for myself.
Does the rating go off of the main breaker or buss bar?
