Possible and How?

[YankeeFlyGuy]

Hello! These are questions I plan to ask my electrician when I hire him, but I want to make sure he gives me the correct answers.

What size wire and breaker would I need to run electric to a small campsite shower house that is exactly 200' from the main panel in my barn? I would need to power an RV outlet, 3-4 lights, a small water heater, and 2 outlets for hair dryers, small heater etc.

Can I run it to another small panel in the shower house so I have a cut off switch there instead of running back and forth to the main barn panel?

Thanks!

You'll need to run fire wires (two hot, neutral, ground) to a panel, which will also need a pair of ground rods. Size of the wire depends on how big a panel you plan on. 60A is probably plenty, for that at that distance, probably 2-2-2-4 MHF for direct burial. Similar size individual conductors if you're going to run a conduit. Do a load calc based on the actual appliances you're planning on, and any expected growth (RV hookup?), because you might get away with less, which would take smaller, cheaper wire. d

Just blurtin' in here...
Elec. hookups in most RV parks are either 30amp or 50amp.
30 should power one rooftop AC and a microwave, but a big RV with 2 AC's running needs 50 amp. Just blurtin' in here...

2-2-2-4 AL Mobile Home Feeder in conduit to a sub-panel is a common solution. MHF is rated for up to 90 amps, so it should work well for about 60 amps and 200 feet. Allowing for line loss, you could probably run more than 60, but I don't know the exact calculation.

Given the small space and intended use, I would consider a weatherproof, lockable, sub-panel mounted on the outside. You need 30" wide unobstructed access to the sub-panel, and it should not be in a bathroom, and that would be a lot easier to get when mounted outside. Then use conduit, wet-rated wire, and GFCI's for all the receptacles, since they may be exposed to water.

Great advice on both wire size and the panel location!

Thanks guys.

Final CO is planned for this week on the building then the Electric starts.
