Hi I am not sure this is the correct group, I will appreciate referral to the right one. I ran ~35" wire from the electric dryer outlet to the circuit breaker box. I asked in Home Depot which wire to use, I was told that 12AWG is adequate. I finished the wiring, and AFTER that noticed that the dryer label says that 10AWG is required. I noticed few places on WWW saying that
12AWG is for 20A circuits.The wire is connected to the 30A breaker, it is not buried (just stapled to the basement wall). I estimated that there will be no more than 10-15 degrees C wire temperature rise (very conservative estimate, 30A current). It seems safe in basement (New England area, ambient temperature never exceeds 40 deg C), the cable insulation has
80 deg C rating (I think). What does Electrical Code say? Do I really need to rewire the darn thing? Thanks
