What kind of extension cord should be used to plug into shore power?
Avoid using extension cords not designed for RV use. Typical extension cords will offer limited current carrying capability. Use only extension cords with a minimum amperage size of 10/3 or larger. Use care not to overload the cord, causing a resulting burn to spark a fire. Never use an electrical adapter that appears burnt or melted. Discard adapters that are worn. Discolored terminals or adapters will create loose connections. The length and size of the extension cord is important. If the RV is situated so as to require forty feet of extension cord, the cord must be rated for the length of that location to avoid overloading the amperage of the cord.
