Been trying to do this for 3 years. first guy ripped me off for 650 bucks then never came back. Did nothing...... Set me back 3 years on running electric to my barn and out buildings..... I have measured the distance from the box in the basement to where I am planning to put the junction box in the barn. roughly 200 ft. ... I want basics in the barn but I'd like to branch off from there to a garage about 40ft to the right with enough power to run my small welder and lots of lights and a small compressor . Thats about all I know.... Do I need 3 phase - 220 - 110 ? Any advise on getting the supplies economically ? Not trying to cut corners (dont wanna burn my barn down) but I am on a tight budget. What is best for running under ground ? conduit? A friend is going to loan me his trencher.... I dont even know what else to ask at this point so any thoughts and suggestions would be helpful
Thanks
Wade

The question is not "do you need 3 phase" but "can you get 3 phase" Its not available every where.
Only you know if you have 3 phase machines and 'need' it.
200 feet to my barn was expensive but I put in a pole and the electric company ran the wire for free. If you want to bury it, look up the designation for buried wire (is it NM?) (NMC?) just look it up then you can price it
You aint sposed to do this and fer shure dont bury romex but I ran 12/2 with ground down the fence for temporary. One for lights and stuff and another 12/2 for the welder. It worked just fine and I did it right as soon as I could
I googled, its UF for burying and of course the additional cost of plastic pipe to put it in is worth while. Consider where you bury so that you always know where it is and put in where you will never dig again

Good advise brewswane Thanks. I will look into all that. I m not sure why I was told I should have 3 phase. Enen my welder is just 110. I think they where just advising me to get as much power as I could.

If you wish to run a welder, compressor, and lights, all at 110 volts, you may be be talking about 50 amps or more. If you run AWG 10 wire, 240 feet, voltage drop will be almost 25 volts, which is way too high and could damage motors. Connecting the welder and compressor at 220v will at least cut the current and voltage drop in half. I recall 10% voltage drop is about as high as you can tolerate. I also think you should put in a separate ground rods at the barn and other connected buildings. Best option would be to have a separate service brought to the barn, with a meter and panel, as was mentioned. Then you can have all the current you want. Problem is that once you have electricity out there, you'll find all sorts of reasons to connect more things. I connected outbuildings to my barn service by running poly irrigation tubing underground, keeping it watertight. I believe I used 1 1/4 inch tubing, which is pretty stiff, if you're running under a driveway, etc. But still pretty inexpensive. Then I just pulled plain wire through the tubing. Make sure the tubing exits the ground and rises several feet above ground level before connecting it (through barbed connectors) to PVC junction elbos. |

BSAschields: Don't skimp on electric to your barn's. You will only regret it. $$ spent now will pay back many times in future. I put 100a in my barn, and now wish I had put in 200a. As brewswane stated, 3ph is usually more of an "if you can get it" question around here. Unless you are using or plan on using a lot of old 3ph machines, it probably isn't necessary anyway. Usually pretty pricy for the average home shop. And if it is needed, you could always do a rotary phase converter.. If you put enough power in shop to run the converter. Checking with a qualified electrician will be $$ well spent IMHO. Paul is right on, black poly irrigation tubing or plastic well pipe is good way to go for reasonable priced leak proof conduit. Comes in nice long rolls if needed. And don't forget to put in an extra conduit for phone/cable/internet when you have the trench open. Oh, and water....
Let us know how you come out and post up some pics of the progress.

Look in the yeloow pages, i know no one uses them anymore, and look up used/salvaged electrical supplies. They can hook you up with panel, lighting and maybe your wire at a good savings.
