A motorized trailer home or RV runs off the batteries of the vehicle most of the time. The RV does have a converter that can connect the trailer home to a 30-ampere (amp) or 50-amp outlet located at trailer parks that provide power. The 30-amp plug has three prongs, while the 50-amp plug has four prongs.
The typical trailer home is the pull-behind trailer home. These trailer homes also have the ability to connect to electricity as long as a 30-amp or 50-amp outlet is available. The plug is generally located at the back of the trailer home and easily accessible through a panel that opens and closes.
The difference between the RV trailer home and a modular trailer home is the size and ability to move the trailer easily. A modular trailer home is about the size of a single-story house and is tied down or anchored to one location for a long time. These types of trailer homes can also be attached to electrical connections. The type of electrical connection used for these trailer homes is the same as the electricity used to connect a residential house. A electrical meter is installed by the local power company and hard-wired to an electrical panel inside the trailer house. An electrical connection such as this must be made by a qualified technician to ensure the connection is done safely and it meets local regulations.
Some older RV trailer homes do not have a 30-amp or 50-amp plug. If this is the case, you will have to hard-wire the trailer home to an outside electrical breaker box. The electrical wire will run from a panel located inside the trailer home to a temporary electrical box located on a pole with a electrical meter attached. Ensure that the electrical wire on the temporary power supply panel is connected to a breaker that handles at least 50 amps and is turned off before making the connection. The electrical breaker box located inside the trailer home will have a place to connect the electrical wire and already has the breakers required. Make sure that all the breakers in the box are in the "Off" position before making any connections.
