DW and I are going to be stuck in a 30A site this summer.. Right, Wrong or Indifferent we are energy hogs and from experience know that we will be popping that 30A breaker all the time.
And so was wondering... If I plug a regular extension cord into the 15A socket in the pedestal ... will I be getting a total of 30A +15A = 45A of electrical service? If so... I could plug a few devices (like our dehumidifier, dryer and external ice maker) into that extension cord?
Thanks... ohhh.... I would bet it would depend on "how the pedistal is wired"... if so, is there anyway I could test it other than TRYING IT?
Yes, running a separate cord to provide power to plugged in 120 volt items will work. They should be on two different branch breakers in the pedestal. The 15/20 amp should be GFCI protected. Use the heaviest gauge of cord you can find. #12 would be adequate. Some larger hardware typew stores may even have a #10 which would be better.
I would be careful about plugging dryer in. Check wattage or amperage.
Yes I have been doing this for many years. Best way I found to check if each is independently protected by a breaker, is trip the 30A and see if you still have a live 15 or 20A. Most campgrounds breaker them independently. You could also ask management.
