Question:

Can I feed a 1 phase 200 amp load center with 125 amp wire and circuit breaker?

Thomas Donnelly

A

Answer:

Hey Thomas thanks for your question. Yes. The 125 ampere "wire" and circuit breaker must be "suitable" for the load as stated in 215.2 and 215.3. Also make sure the terminations are rated for the conductor size being used as stated in 110.14.
