The NEMA TT-30P to NEMA L5-30R adapter feeds a 30 amp twist-lock load from an RV pedestal. The plug is a NEMA TT-30P, the socket is an NEMA L5-30R female twist locking receptacle, and both sides are 30A 125V three wire.
Straight blade at the pedestal, locking at the equipment, protected in between. That combination is what boats, food trucks and small work trailers need when the shore inlet is L5-30 and the available outlet is a park pedestal.
Marina berths with a NEMA TT-30 pedestal and an L5-30 shore inlet, food trucks parked at RV sites, and rental equipment that has to lock its connection so a passer-by cannot unplug it. The twist lock also keeps the joint tight under constant vibration. For the reverse direction, an NEMA L5-30P outlet to a NEMA TT-30R inlet is available.
Twist locks need a positive quarter turn to seat. If the NEMA L5-30R ring will not turn, check the blade orientation before forcing it. A partially seated locking plug is a bigger heat risk than a straight blade plug.
Both ends are 125V. This part does not convert to 250V equipment and does not change the current available from the outlet.
Common questions about NEMA TT-30P to NEMA L5-30R RV surge adapters
Boats and small craft with 30 amp shore power, food trucks and concession trailers, and some rental or work equipment where the inlet has to lock. The L5-30 is a 125V, three wire, 30 amp locking standard, which is why it pairs with an RV pedestal supply.
Only if the outlet you are given is a 30 amp straight blade RV receptacle. Many berths use NEMA L5-30R outlets instead, and for those the part is the NEMA L5-30P to NEMA TT-30R adapter. Check the outlet before you buy.
Yes, that is what it is for. Push in and turn a quarter turn until the ring seats. If it will not turn, check the blade orientation rather than forcing it, because a partly seated locking plug is a worse heat risk than a straight blade plug.
No. Both ends are 125V, three wire, 30 amp. The L5-30 standard is a 125V locking configuration, and a 240V load needs a different connector and a different supply.
