UF Cable

[jemsvcs]

Installing a receptacle for a 230V 50A welder in a garage that is 300ft. from the utility pole. The property owner is requesting the cable be run underground. Based on voltage drop at this distance I am coming up with 2 AWG for this application to keep the voltage drop under 3%.

It seems like 300 feet of UF containing two 2 AWG cables and an ungrounded conductor and a ground would be a huge cost. Any ideas or alternatives? Feel free to check my math!!! :roll:

Vd = ((2x10.8x300/66360)x50)/230 = 2.1%

Re: UF Cable

Now you see why there are so many t-formers in the neighborhood. Check with the utility, they may agree to spread the cost of installing a t-former closer to the garage over several years. But 1,000 feet of #2 Al will cost less than the labor to dig the trench.

Re: UF Cable

Based on a software program that I have, I got 2.4% drop so your calc. is reasonable. Is the load actually 50 amps, or something less?
