Circuit Breaker Sizing

Maximum circuit lengths for various circuit breaker amperages are shown below. Circuit breaker sizing should be based

on the local or applicable code.
Ground fault protection equipment is required for each branch circuit supplying electrical heating equipment. Consult

local authority for ground fault circuit protection.
