Harm in Reverse Polarity?

I have seen several threads talking about surge protectors and looking for reversed polarity, my question is simple, it is really going to have a negative impact on my RV?

If I am at a site for a weekend, should I ask for a different site if it is reversed, or is it something that will not make too much of a difference happening occasionally and should try to avoid, but not fuss too much if it is there?

Thanks.

Mike Sokol, who is a member of the Forest River Forums, also has 12 great articles called "no shock zone" that can be found here:

Reversed polarity is the reason cords now have polarized plugs to appliances and lamps. To over simplify it (not bringing equipment damage into the picture) it could..... 1) Do nothing..... or if conditions are right.......... 2) you could receive an electrical shock ...... or 3) it could kill you or a loved one.................. so what what you do is up to you but............. I would change sites...... Sorry if I may come across a little blunt but I investigate too may workplace deaths........ I would not care to be at a campground when an accident happened........... and yes about 25 years ago I received a rather healthy electrical shock from an 1988 Terry camper was it reversed polarity ? I really can not tell you but I was not a good thing.............

Absolutely request a new site, and test that one too. You would not tolerate a reversed polarity situation in your home.

Camping can be a damp experience: rain, morning dew, leaking hose, kids playing, etc.

Maybe you won't have a problem, or there is a 1/100 chance of a problem. Don't risk human life with the 1% chance. If you know there is a problem, take action.

I had one CG employee tell me my tester was incorrect. When I insisted on them checking it, guess what? There was no ground or polarity was reversed. Another CG employee who was showing me to the site got upset when I wanted to take time to test. "We wouldn't put you here if there was something wrong!" Sure. At a state park the lights on my tester didn't jive yet they insisted everything was good. I could smell "electric burn" and insisted on them having it checked. Two out of the three wires were fried. ALWAYS CHECK!

It is one with three different LEDs and if the proper ones aren't lit there is a problem. I also keep one plugged in inside to keep an eye on the voltage + my surge protector has an indicator on it also. The one I use initially is very inexpensive. Here is a link to it on EBay and I am sure they are on Amazon + I think Harbor Freight also has them.

If polarity is reversed you will be energizing the neutral instead of the hot leg of your camper; it will "work" but with great danger of damage, injury, or worse. Definetely check before you hook up & move it is wrong. No ground could be even worse. Most plug in & hard wired surge protectors will detect & warn you of any problems before you hook up. Be careful everyone & safe & happy camping.

My EMS-PT-30 is great on testing but was wondering if there is a simple plug in tester that you can slam into 30 amp socket before pulling everything out to hook up?
