Simple question. Are two 45amp loads on a 10 gauge wire running at 90amps or at 45amps? I know, I know....I'm an electrical dumb a$$....:rolleyes:

90 amps, which is WAY too much for 10 gauge... or 8 gauge for that matter. (8 gauge = 75 amps continuous)

Either run another wire, or run 6 gauge.

Yeah but....

I went here and 6 foot calls for 10 to 12 gauge. I'll definately take your word and run 6 gauge....but why the difference in opinion? Just playing safe?

I went there and it spit out 8AWG for 90 amps at 6 feet. Remember, the smaller the gauge (numerically) the less voltage drop. There recomendation for 12 volts is a 3% voltage drop. That's .36 volts for 6 feet. So your load will be seeing 11.64 volts. Not good.

Kirchoff’s current law, “The sum of the currents flowing into any point in a circuit equals the sum of the currents flowing out of that point.”

Simplified:

Currents in series add.

In paralell, total current is the sum of all branch circuit currents.
