Question. If I double say, two 14 gauge wires, what is the effective new gauge. I thought I read it changes the gauge by 3. So double 14 would be 10 ? Not interested that not NEC approved, just the theory. Thanks

I'd think it's the same as the area of the wire size... as in 2 14 gauge in square mm is the same as 11 ga.... Two 10 gauge is the same as 7..... seems about right!
And, the voltage drop calculator linked below lets you select more than one wire used, like 2 14 ga, etc.

I found the info on doubling online easy enough a couple years ago.
If I understood it right:
The downside is each line needs to be 'fused' to the actual wire gauge because if one wire fails all the load goes to the other wire. Iirc the safety recommendation is to not exceed the max rating of just one wire.
The upside is that you can counter the line loss but at the cost of wire.

What's this for? What voltage and amperage are you putting through it?

Why would this matter? It's just a simple question

Because of ohms law..electrical theory basicly.
