WELLUCK 50 AMP RV Circuit Analyzer, 50A 125V/250V RV Pedestal Tester with LED Indicator Light 14-50P 50 amp Tester Plug for RV Camper, Travel Trailers (ETL Certified)

These work well just plug them in and know if the power pole is set up correctly. And if there is an outage in the RV they help you locate if it is inside or outside for quick Diagnoses...

This little device saves us from disaster!

Seems to be a well built tester that feels solid. Worked great to test the pedestals in this campground.

Easy to use.

Great device to have so you wont blow your RVs Converter

worked as advertised. My electrician even used it after WallBox blamed my 240V outlet for their faulty product based on a ground disconnect. I think he decided not to charge me for the follow up visit after using my Welluck circuit analyzer.

Great tool to have.

So far, this little gadget detects bad circuits. Could save you lots of $$ if you happen upon a bad plug.

I pull into a campsite, plug this in, if it tells me everything is ok I plug in my 50 amp cord. I have a built in

Bought this device to check electrical hook ups at campgrounds before plugging in my camper. Works great and tells me if the power is okay before I plug in.
