Marinco 117A Shore Power Pigtail Adapter, 30 Amp 125 Volt Locking Male to 50 Amp 125/250 Volt Locking Female

The Marinco 117A is a shore power pigtail adapter that lets you connect a 30 Amp 125 Volt dockside power source to boat-side equipment or a shore power inlet wired for 50 Amp 125/250 Volt service. It bridges two different power configurations so you can plug into whichever pedestal or receptacle is available at a marina without needing separate cordsets. The dockside end is a 30 Amp 125 Volt locking male plug, and the boat-side end is a 50 Amp 125/250 Volt locking female connector fitted with Marinco's sealing collar system for use in wet locations.

Both ends are fully molded for durability and water resistance, and the connector includes protective covers. A built-in LED power indicator shows at a glance when the adapter is energized, and a contoured grip with a thumbprint ground blade locator makes it easier to orient and connect the plug correctly, even in low light. The adapter is UL Listed and finished in yellow for high visibility on deck or dock.
