This is the 30 to 50 amp RV surge adapter with the indicator fittings: LED status lights on the housing and a weather cover over the NEMA 14-50R socket. The plug and socket are the same as the plain 30 amp to 50 amp adapter, so it steps a 50 amp coach cord down to a 30 amp pedestal in the same way.
Rated 30A 125V on the plug side and built to UL 817 with UL and cULus listing. The cover keeps rain and grit out of the receptacle between hookups, which matters at sites where the pedestal faces the weather.
Pick this version when the adapter stays plugged in for weeks at a time: the indicator gives you a status read at a glance, and the cover protects the socket face when the coach cord is unplugged. Same 30 to 50 amp job as the 30 amp to 50 amp adapter, same limits: 125V, up to 30A.
Read the indicator after the first hookup, not after something stops working. It reports the state of the supply you are plugged into, so a fault at the pedestal shows up before it reaches the coach.
Indicator and cover are the only differences from the 30 amp to 50 amp adapter. Specify the indicator version if you need those fittings.
Common questions about NEMA TT-30P to NEMA 14-50R RV surge adapters
The panel reads the supply the adapter is plugged into, so a fault tells you about the pedestal before the coach cord goes on. Treat an indication of a fault as a reason to move to another pedestal or to report it to the park, not as something to work around with a second adapter.
No. The cover keeps rain and grit off the socket face while the coach is unplugged. The adapter is not submersible and should not sit in standing water or on wet ground. Hang the joint clear of puddles the way you would with any hookup.
It is the connection people make most often when they move between sites. The indicator confirms what the pedestal is doing before the coach is connected, which is cheaper than finding out through an appliance. The electrical rating is unchanged from the plain 30 amp to 50 amp adapter.
Yes. Samples are available, production starts at 200 to 1000 pieces and lead time is 15 to 20 working days. The label, the shell finish and the packing can be set to your programme; the electrical part does not change.
