Question need to talk to someone who has run a wire from their house breaker box to another bu

We just built a shop about 135' from the house. We'll be using #6 wire. Do we have to run a return wire from the shop back to the house?

yes, you will have 4 wires...2 hots, 1 neutral, and 1 ground...all going back to the house.

you should be able to find 6-4 cable if #6 is indeed sufficient for your amperage over that distance.

for clarification, I am using the word "wire" to mean ONE conductor....and the word "cable" to mean a bundle(of sorts) of wires which will be color coded...probably red/black/white/bare...in this case.

you can run a 50 amp circuit and stay within the voltage drop tolerance, any more and you'll have to use a higher gauge conductor.

We need more information before we can begin to answer this. What are you installing in the shop, a repcept, a few lights, or an entire sub panel?

If a sub panel, how many amps is it rated at?

If a recept to plug in equipment, how many amps does the equipment draw, and at what voltage?


You will either need three wires, or four, depending on what you are trying to accomplish.
