Wire Gauge


I'm installing a 4000W in-wall electric blow heater. It will only draw 16.7 amps. My question is, can I use 12/2 romex for this circuit or do I have to go with 10/2.

20 amp circuit and 12/2 should be fine.

actually NO remember the 125% rule with heaters. 17a x 125 = 21.25a too much for a 20a circuit. The next size is 25a but most people skip to the next size 30a and you will need #10 wire

Thanks for the info....I did some research and found that although a 20a circuit would probably work, it is not up to NEC code since it is a 4000W heater. I will go with a 30a circuit and use the 10AWG wire.
