Default Wire gauge

For my rims I have a 1500w element. I was wondering if a 16/3 wire is the right gauge to safely wire it?
Thanks guys, MJ

No. You need a 20 amp circuit, so you need #12.

yep, 12 AWG for that bad boy. Make sure you have it plugged into a 20 amp circuit too.

Thanks Bern. Guess I'll have to exchange the cord.

This was what I thought would work. Wrong answer.

As two of the previous posts mentioned, you also want to make sure you use a 20 amp circuit. Electricians, please correct me if I'm wrong, but I believe you don't want to exceed about 80% of your amperage rating, so that would be around 16 amps on a 20 amp circuit. Just something to keep in mind in case you have additional things plugged in on the same circuit.

I have a HERMS using two 1500 watt elements (one in heat exchanger, one in HLT) each plugged into a dedicated circuit. The only 12 AWG cords I could find at Lowe's were the ones intended for window AC units. I can't remember how much I paid, but I want to say they were around $12 each.

So another question. I found a spool of 12/2 that has a copper ground in it(should that make it 12/3) 600 volts. It's romex wire. Will this be capable? I know, I know.....electric noob.

12/2 INCLUDES the copper ground. 12/3 will have a red wire that is generally used as an extra hot wire for a total of 4 wires (white, black, red, bare copper or green)
