ABSTRACT:
An adapter for connecting an electrical load which is mobile, such as the electrical system of a pleasure craft, to a stationary power source, such as the electrical pedestal at a marina. In its preferred embodiment, the adapter serves to connect a higher voltage load (such as a 240 volt electrical load of a pleasure craft) to a pair of conventional 120 volt sources. Input cables include a pair of connectors for independent connection to sources on the pedestal. Isolation means within the adapter serves to isolate the input connectors from each other during the connection operation such that a user holding one connector while connecting the other will not receive an electrical shock. Sensing means within the adapter determines that the sources are in the proper relationship to sum to the level required by the mobile load. When the sensing means determines that the sources are connected and in the proper relationship, contacts are closed connecting the summed inputs to the output for driving the load. In a preferred embodiment, a portable adapter is shown having circuitry which is self contained within its housing.
