Valterra 50 Amp Circuit Tester | 4-Wire Receptacle Fault Detector

Not every campground pedestal is wired correctly, and a fault on the shore power side can damage sensitive electronics inside your rig before you even notice a problem. This tester plugs into a 50 amp, 4-prong outlet and reads back the wiring condition through a set of indicator lights.

• Detects up to 9 different wiring faults in 4-wire receptacles
• Rated for 50A, 125/250V service
• Indicator lights give a quick read on circuit condition
• Corded design plugs directly into the outlet being tested
• Built for 4-prong plug outlets specifically

A cheap habit to build: plug it in, check the lights, then connect your rig — instead of finding out about bad wiring the hard way.
