Weird Wired Power Pedestal

Upon hooking up to electric I turned all breakers off, plugged in my 30 amp cord and turned on the breaker marked "30."

Went for a walk, etc. Couple of hours later wife went to turn on microwave and it had no power. I went to the power pedestal and reset 30 amp breaker with no results. Thinking I had confused the 20 amp with the 30 amp tried that. Nothing.

Unplugged cord and reinserted, again nothing.

Scratching my head I try above steps again thinking I must be overlooking the obvious. Nothing.

Then I flip the 50 amp DOUBLE pole breaker. Bingo. Why I did that I don't know, out of frustration I guess.

Whoa I think. Someone screwed up big time. Remember this is a 30 RV. I look again to see if I missed something. Did a second look in disbelieve there is NO fifty amp outlet in the pedestal.

Now I am getting a little nervous thinking I am going to see the smoke of burning electrical equipment that was only meant for 115 volts. Pulled the cord out and checked for the proper voltage, everything good except there is a 50 amp breaker instead of a 30.

Going to check a couple of empty sites in the morning to see what the have in the pedestal.

The DW just asked what I wanted for Christmas I said "Progressive Industries EMSHW30C Surge Protector, it is in the Amazon wish list." "There is also a transfer switch in there too." The explain what they are. Maybe if I am real good...

Beachside State Park, Oregon site 82. I wonder how many others have plugged into this site and never questioned its power setup? Sending a e-mail to the park system in the morning after I check a few other sites.

  • You're sure there's no 50A receptacle around? Maybe there was at some time.

    Of course, it's not unusual when there is a 50A circuit (and a 30A circuit) to have the 50A breaker be a main and the 30A (and 20A, assuming there's one of those) fed from legs of the 50A internally. Probably either there is/was a 50A previously, or they wired the place with the place with an eye to upgrading the sites at some point in the future...but who in their right mind would go to all that much trouble and then not spend the extra $25 or whatever for a 50A socket?

    At any rate, I expect you'll find you need both the 50A and the 30A breakers on to get power. No safety issues if that's the case (assuming the voltage and polarity are correct etc.); there's nothing in the electrical code that prevents having multiple breakers in series for a circuit, even when it's not particularly useful to do so.
  • For a few bucks you can get a device that tests the circuit before you plug your cord in. It tests for a proper ground, correct wiring, etc.

    Never Plug your RV in without testing the power first.

    Tester

    To use this to test the 30 amp plug, just plug this tester into a 20 amp to 30 amp connection.
