The NEMA L5-30P to NEMA TT-30R adapter takes power from an L5-30 outlet and presents a 30 amp RV receptacle. NEMA L5-30P locking plug at the supply, NEMA TT-30R socket for the trailer cord, 30A 125V on both sides.
It is the part for the awkward connection: a locked outlet on the dock or the shop wall, and a travel trailer that needs a standard RV receptacle to plug into.
Boat owners who keep an L5-30 pedestal and also tow a camper, shops and yards with locking 30 amp outlets, and transfer setups where the feed is L5-30 and the load cord is an RV cord. Reverse direction is covered by the NEMA TT-30P to NEMA L5-30R model.
Check the locking collar on the supply outlet before you tighten the plug. A cracked collar lets the plug work loose under vibration, and a loose locking connection arcs at the blades.
The outlet must be 125V. L5-30 is a 125V locking standard, so do not use this part on a 250V locking outlet.
