It's approx 100' from the house to the garage. I just installed a 100 amp breaker box in the garage and now I need to run electric from the house to it.
What would you suggest? Size 4 or 6, copper or alum? What would be the advanges of either? I want to hold down cost as much as I can but, be safe. Also, it's needs to be underground wire.
Do I need single strand wire? Or can I get the same wire with 2 wires and a ground included?
One more thing to think about, at some point in the future I am planning to put a small 30amp welder in.

2-2-2-4 aluminum wire. Type USE or URD for direct burial. Aluminum is much cheaper than copper and works just as well as a feeder such as you are talking about. It will be stranded wire. This is a wire assembly containing 4 wires. Email if you need more information.

It depends on how much amperage you are going to be using. Just because you have a 100 amp panel, does not mean you will use all 100 amps. For a garage I would recommend about 50 amps. Which would only require a 6 gauge wire size. If you buy aluminum you have to go up one size in wire in this case it would be a 4 gauge. and yes a 6 is smaller than a 4 in the wire world. You can buy what is called 6/3 (six three) with a ground in copper. In aluminum it is called a 4 4 4 6. That is the easiest way to do it.

You should get #1 size wire. If you are going direct burial the you need UF cable instead of the regular romex. If you are planning on running 220V out to the garage then you need to get #1 /3 with grd. So you will have 4 wires in the cable. You should also use a GFI outlets when you start putting things in.

since you are putting in a 100 amp box you absolutely need #2 copper or #1 aluminum....i would also recommend you put all of this in conduit but you can use uf wire 2/3 with ground would do the job in copper or 1/3 with ground in aluminum would work....copper works the best with no oxidation of the wires or where they connect to the boxes...aluminum is somewhat cheaper but overall qualities does not compare to copper...it would probably be a good idea to install another ground rod at the garage..

the size of the wire is dependant on the size of the breaker feeding it. for a 30A service #10 would work. I am assuming that you want more than that tho. for a 100A service you would need #2 cu or #1 al. you can get triplex cable that has two hots a neutral and a ground in a sheath at most home stores. If you use aluminum make sure you coat the stripped ends with nolox or a similar compound to prevent oxidation.

if you're gonna run a 30 amp welder, your gonna have to pull power on the building (get a seperate line just for the garage)
until then you need 10/2 wire with ground fault-it's big enough and you can bury it

Go for the #4 strand Copper and not worry about overload when you add other tools.
Use at least the best PCV and mark it. jr.
