To start with a 30 Amp system is the most common on RVs. The plug on your RV is a large three-prong, heavy duty 30 Amp, 120-volt plug. Most campgrounds you go to will provide you with a 30 Amp outlet that your RV power cord will plug directly into.
Are RV plugs 110 or 220?
Outlets configured to deliver 220v should not be used directly for an RV application. The RV system requires 120 volts. Putting 220 volts into an RV electrical system will damage or destroy the appliances and other systems in the RV.
Do you need special extension cord for RV?
Yes, you can extend your RV power cords length with an extension cord, but you must use one thats properly rated to carry the amount of current you need to use. Never use a regular household extension cord for this purpose. Bear in mind that youre dealing with high amperage (current) and will be using it outdoors.
How long of an extension cord can you use on an RV?
RV Cords are 25 feet in length. As long as someone sticks with the cord that came with the RV and one 25 foot extension, they will never exceed the 50 amp rating.
