The long run

[BSAschields]

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

I think you only need 240V single phase. I would use conduit underground with #2/0 aluminum for 100 amp to the barn and then to the garage with #2 Al in conduit for up to 90A at the garage. This is just my thoughts not knowing your service size back at the house.

Run the big feed to whichever building you will be using the most power in, then run a feed from there to the other building.

If the distances are such that you need to "T" the lines, you could bring them up out of the ground to a post, junction and disconnects, etc, but bear in mind that doing this could cost more than the additional wire to simply run from house to bld 1 then to bld 2. (due to buying expensive weather proof junction box, post, connectors, etc.

You will only need 3-phase if your machines require it! Even then, most PoCos do not offer 3-phase service for residential customers! And the nominal voltage for typical single phase service is 120v/240v not 110/220! Do u possibly have 3-phase service? If u do, that's a whole nother can o' worms and i don't recommend newbies working on 3-phase service!

You will need a 4-wire feeder- 2 hots, 1 neutral and 1 ground/egc. You will need 2 ground rods spaced 6' apart @ each detatched building, a main disconnect panel if using more than 6 breakers(2 pole w/ common trip for 240v feeds counts as 1), and the neutral bus bar needs to be insulated from the enclosure AND the ground bus bar(there's usually a bonding wire that runs from either the ground bus bar or is screwed into the panel). You could use conduit or direct burial wire but be aware that not ALL direct burial wire is permitted to be run inside!

Good info Thanks. Hopefully I will be a smarter consumer now

Call the first guy back, get him to do the job, ( he probably does not remember you ) let him do it all, when he hands you the bill, say thanks, I already paid you 3 years ago, good bye and get off my property.
Other then that, good info here in the post. not much I can add unless I want to start a fight on the voltage values .
