Do I install a 220v, 230v or 240v permanent power supply line?

Hey all,

I’m in the position of possibly moving into the driveway of a community house, and we’re exploring installing a 240v hookup for me. How do I know what my rv (https://www.gulfstreamcoach.com/media/uploads/1/11146_1997-Yellowstone-CC-Class-C.pdf) uses as far as power? The spec sheet above only has that the rv is equipped with 110v outlets, but there’s a 15A wire/plug coming out of the side compartment, and a high-volt, three prong outlet in the same electrical compartment. My friend who has more experience than I says this outlet is for 30A connection. How do I know if it’s best to use 220v, 230v or 240v power supply being installed in the community house? And can any of these voltages allow 15 and 30 Amp plugs?

Thanks for any leads/information, *newbie* Mark

PS. I was fine at an rv park with the 15A plug because I was using the propane furnace. Is the 30A plug going to be more expensive draw for the excess power I don’t need? Sorry, I don’t understand Amps and Volts, and their differences. : (
 
Mark, I advise you to inquire with a licensed electrician in your area as RV power pedestals often have required codes that need to be followed and may also need to be permitted.

That said, the average RV uses a 120 volt, 30 amp, 3-prong (1-120v hot, 1-neutral, 1-ground) power supply. Although they can look like a 240 volt, they are not, and a 240 volt supply (2-120v hot wires, 1-ground) should not be installed as it will damage your RV and all of your electrical devices!

I would want the 120v, 30 amp supply installed. It provides the ability to draw more power when needed or desired, say to run the air conditioner in the summer, an electric heater in the winter, or a hair dryer and the coffee pot at the same time.

The 30 amp would be more expensive initially because of the more robust wire and components, but you only pay for the power you draw, or use, regardless of what the components can handle.

I hope this helps. Good luck.
 
Thanks Leisure time Larry,

I learned a lot. I have a friend doing work on my electrical system, so I'll ask him. If he doesn't know, I trust he'll steer me in the right direction.




Thanks again for replying, Mark
