The Reverse “Y” Adapter has two male plugs with special power isolation circuitry for added safety. When one plug is connected to a
receptacle, the circuitry isolates the second plug. The reverse “Y” provides 50A 125/250V power when only two 30A 125V
receptacles are available.
Note: Reverse “Y” will NOT work with 50A, 125V, 3-wire inlets. Power is provided in both circuits to the 4-wire inlet, but the dock side
receptacles limit the current in each circuit to 30A. The two 30A 125V receptacles must be supplied from a single power source
providing from 208V to 250V between them for proper operation.
