Normally, a multiwire branch circuit consists of two ungrounded conductors from two circuit breakers that are the same amps (say 10 amps) and they'll share one neutral.
Is it permissible to use a 15 amp circuit breaker and a 20 amp circuit breaker as long as the neutral wire is sized for the 20 amp circuit. Why or why not?
Let's say this multiwire branch circuit had a neutral that was sized for the 15 amp breaker. What would happen?
I could not find an answer in the code or Mike Holt's illustrated guide to the NEC.
Thanks for your help.
