Another Electric Wire Size Question

[diamonde40]

I know this has been discussed and asked many times but I am looking for a simple answer to my question if possible from our electrical experts:

At meter pole- 200 amp service
Wanted at shop- 200 amp service (minus the drop for distance)
At shop- 200 amp circuit breaker box
Distance from service pole to shop circuit breaker box-150 ft.
Direct buried or in conduit?
Copper or aluminum?
SIZE OF WIRE PLEASE?

Thank you for your help

I always put underground wire in conduit, copper is my preference.

Based on those 2 criteria 3/0 copper would be the required size.

Check out the voltage drop calculator. You can check your wire size:

Id use aluminum feeder wire, in conduit.

3/0 copper or #250 aluminum feeder

Someone in the classifieds was trying to move some 250 aluminum.

Thanks for the heads up. Texastaxi has 3 pieces of 100 ft. and I need minimum 3 pieces of 150 ft. Thank you sir.

4/0 aluminum in conduit, and it is cheap!

You can use 4/0 4/0 2/0 alum and put in a 2 1/2 conduit. Nothing is wrong with large alum and will save you a lot of money over copper and you will never know the difference
