a home insp. just caught this on a insp of a property i have. the elect. stove is on a allm 6/2 wire with a 30 amp breaker. the stove requires 40 amps! however he is requiring the wire be changed not just the breaker. he wants 8/3 copper on a 40 amp breaker is this needed or can i just cahnge the breaker/ also can some one tell me the code number for amp ratins on allm wire?
you would need 8/3 becuase the 6/2 doesn't have a ground. You could get away with 3 wire in an existing intallation, but if you are changing the breaker, you have to bring the circuit up to code. no grounding with the nuetral anymore. 310-16 has ampacities for al.
Maybe it is a local code, but I was always told that if you touch a circuit, you have to bring it up to current code. I can't find it in the NEC, but if it isn't a code rule, I wonder where it came from? anyone else heard of this?
