A bad pedestal connection can fry your RV's inverter, charger, air conditioner, or refrigerator in seconds. The Camco 55309 PowerGrip plugs into any 50-amp campground outlet and reads the wiring status instantly through a color-coded LED panel -- no multimeter, no guessing, no risk to your rig.
Full-timers, weekend warriors, and seasonal travelers all know the anxiety of pulling into an unfamiliar campground. Pedestal wiring varies wildly -- open grounds, reversed polarity, lost neutral, and high/low voltage conditions are all common findings in real-world campgrounds. The 55309 catches every one of those faults before your $30,000+ rig is exposed to them.
Just plug the 55309 into the pedestal's 50-amp outlet. The LED array reads the circuit in seconds and displays a fault code you match against the included legend. If something is wrong, you know before any RV equipment is connected. If the lights confirm correct wiring, you plug in your coach with confidence.
Multi-LED array identifies open ground, open neutral, reversed polarity, hot-on-neutral, and correct wiring in seconds.
Oversized, ergonomic grip makes insertion and removal easy even in tight pedestal boxes or with wet hands.
Designed specifically for the standard 50-amp RV service outlet (NEMA 14-50P/R configuration) found at most RV parks.
Housing resists moisture and UV for reliable use outdoors at campground pedestals in all weather conditions.
A standard 50-amp RV service is actually a 240-volt, two-leg circuit -- not simply a "big 30-amp." It carries two 120V hot legs (L1 and L2), a neutral, and a ground. Losing the neutral on this circuit does not just cut power -- it can create a dangerous voltage imbalance that pushes well over 120V to one side of your coach and destroys sensitive electronics. A 50-amp specific tester like the 55309 checks both legs and the neutral/ground relationship, something a 30-amp tester simply cannot do.
The 55309 is a pre-connection diagnostic tool -- it tells you the outlet is safe to use. For continuous protection while your coach is plugged in, pair it with a 50-amp surge protector or an inline EMS that monitors voltage fluctuations and disconnects automatically. Use the circuit analyzer every time you arrive at a new site, even if you already have surge protection installed.
