My load is a wall oven consuming 37A and requires using a 50A power line.
Is it acceptable by the code to use 8 AWG THHN copper conductors which are rated 90 degrees centigrade? Keeping in mind that I am using no connectors except a circuit breaker connection and a breaker connection is rated at 75 degrees. It is a residential installation with the max ambient temperature 40 degrees centigrade (104F), dry location, wires going in the basement, through the walls only, and no attic activities.
I did some calculations by using NEC Table 310.16. The result for the three “Current Carrying Conductors in Raceway or Cable or bundled†at the other parameters above is showing AWG 8 wires for the main conductors and AWG 10 for the GND.
I am trying to relay on an exception that may apply if I am using no connectors except a circuit breaker connection (Circuit is NOT a Branch Circuit that supplies multiple receptacles) and my breaker connection is rated at 75 degrees.
