Shore Power Question


I bought one of the little yellow power post testers that shows if it's safe to use.
My question is, if I plug into the 120 plug and the lights show OK, does that mean the 30 amp and 50 amp. are safe or just the 120 volt ???
I have a pigtail that I can use to check the wireing threw the 30 amp plug, but what about the 50 amp. ?
I've never had a problem but I pretty much stay at well maintained parks because my wife uses a walker and can't deal with uneven ground.

NO it does not, you need to use an adapter to check the 30A, and while you are at it the voltage. RV Electric

It's all 120 volts, just different amperage and each plug is wired differently, so a 20 amp plug could be good but a 30 or 50 amp outlet could be wired incorrectly. Best bet is to get an EMS (Electrical Management System) That checks proper wiring, voltage, cycles and shuts down if voltage drops or spikes and provides safety for compressors and electronics by delayed restart.

Hi Larry & Rita,
If you do not want to personally check the 50 AMP receptacle with a meter each time you connect, consider purchasing a product that does it for you. The product also monitors the pedestal power for defects. Go to Search - surge protector - Camping World for selection of these products.

This is by far the best reviewed product on the market.

Hi Larry and Rita, missed you at the Meet & Greet over the weekend!

Anyway, the answers above are about the best you can get. So far I haven't had any problems with 50 amp setups. They're new enough and used enough so they are usually good. I did find a strange 50 amp setup at Grand Ronde in the RV park there. They advertised "50 amp service" which it, in fact was. BUT it was a 30 amp breaker on one leg and a 20 on the other. It did total 50 amps, but a true 50 amp RV service is TWO 50 amp breakers for a total of 100 amps.

I have found problems with 30 amp setups though.

Checking to see that the pedestal is wired correctly is just the beginning. You really need more protection than that.
