Abstract
An electrical outlet for a recreational vehicle includes a high voltage AC electrical power receptacle and a low voltage DC electrical power receptacle that is powered independently of the high voltage AC receptacle so that the DC receptacle can remain energized when the AC receptacle is disconnected from an AC power supply. The DC and AC receptacles, located at the same electrical outlet, are wired separately to different power sources. This allows the recreational vehicle's electrical storage batteries to continue energizing the DC receptacle, at the same outlet as the AC receptacle, even when it is not possible or desirable to energize the AC receptacle. Therefore, limited functionality can be maintained at the outlet even when no AC mains, onboard generator, or AC-to-DC inverter is connected or in operation.
