This is the same NEMA TT-30P to NEMA L5-30R adapter as the NEMA TT-30P to NEMA L5-30R adapter with the indicator and cover fitted to the housing.
Dockside use is hard on an adapter: salt air, spray and long plugged-in seasons. The cover protects the socket face when the shore cord is removed, and the LED panel gives a status read without a tester.
For a boat or food truck that stays connected for weeks at a time on a park pedestal, and for anyone who wants the supply verified before the shore cord goes on. Ratings are unchanged: 30A 125V, three wire, UL 817.
Rinse and dry the connector faces after saltwater exposure, then check the pins for green corrosion. Corrosion raises resistance at the joint, which is what the heat damage usually starts from.
Specify the version with the indicator when both are wanted. The plain NEMA TT-30P to NEMA L5-30R adapter is the same adapter without those fittings.
Common questions about NEMA TT-30P to NEMA L5-30R RV surge adapters
Yes, and it is the version we suggest for that use. Dockside power is left connected for long periods, so the cover protects the socket face and the indicator gives a read on the supply without fetching a tester. Check the pins for green corrosion after saltwater exposure.
The socket face, mainly while the shore cord is disconnected. It keeps spray, grit and insects out of the receptacle between stays. The adapter itself is not submersible and should not be left lying in water.
Yes, the connectors and the rating are identical: NEMA TT-30P plug, NEMA L5-30R socket, 30A 125V, UL 817 with UL and cULus listing. Only the housing fittings differ.
The NEMA L5-30P to NEMA TT-30R adapter for an L5-30 outlet, or the NEMA L14-30P to NEMA TT-30R adapter where the outlet is a four-wire L14-30. Both are available with the indicator and cover
