Remodeling kitchen. I now have an oven with 8AWG and a 30 amp breaker. The new oven requires 40 amps. The run is 20 feet. Will the 8 awg do with a 40 amp breaker?

Thanks,

Shortround3.

8 AWG - Copper, is rated for 40 Amps.

#8 in NM and UF cable is rated for 40 amps.

#8CU THHN and most other conductor/cable types is rated for 50 amps.
