Start out by using Table 310. 15(B)(16), and applying any required corrections, to determine what size conductors you'll need. For your situation, we'll assume we can use the 75°C column, that you want to use copper conductors, and there's no other c

I have a rule: Nobody does things for no reason. 600A is a crazy amount of service, and if the reason for it isn't obvious, figure it out before you change anything. Once you understand that
I am wiring a house that I built, and code says I need an AFCI for the bedroom circuit. The panel that I will be installing this AFCI breaker in is a subpanel, so my ground/neutrals are on 2 separate buses on opposite sides of the breaker panel. Can
