Voltage Drop

[SparksRFlyin]

What is the proper size wire to run for 175 feet ? All it's feeding is a shed, HPS or MV light on front, 8' shop light, and a motion detector on side of house.

I figured on running 10-2 UF and hook it up to a twenty amp breaker. What do you guys think?

are you running a single pole or 2 pole circuit?
also, are you planning on sizing the drop only for what you install, or the entire possible 16 A that 20 A breaker can safely hold???

Here is a nice little voltage drop calculator.

If I was doing the work, I'd size it for all possible 16 A, which looks to be a #8, maybe even a 6 depending on conditions (and a single pole circuit).....

I did the math and you would be OK up to a 9 amp load.
