Frequently Asked Questions

What size wire for 800 amps?

For an 800-amp service, you typically need 1000 kcmil (MCM) copper conductors or 1250 kcmil aluminum conductors per phase, though parallel conductor sets (e.g., two sets of 400 kcmil) are commonly used. Always verify wire sizing with a licensed electrician and the NEC based on conduit fill, ambient temperature, and termination ratings.
