Yes I must get one ASAP!

Thanks,

So now I'm experimenting by physically touching the center cap and no doubt as I'm grounding my body to the grass there is current going thru me. If I stand up on the concrete and try it again, nothing....
This can't be normal is it?

every new a/s is delivered with a polarity checker, along with the silverware tray, soap dish, tp holder and so on...

it's a yellow 3 pronger, with a row of led lights.
has key stamped on it, for what the various light combinations indicate.

it should be in drawer somewhere and your sales person should have explained usage to you...

cheers

simple answer no.

trailer electrical systems use a floating neutral. that means that the neutral (white wires) is not connected to ground as it is in your house. when the neutral becomes the hot wire nothing happens until you plug an appliance that has a grounded neutral, then you can energize the skin of the trailer.

the absolute worse thing that could happen is the cord of a neutral grounded appliance would be damaged. the basic wiring in the trailer would remain unharmed.

A good grounding in electricity is very beneficial. Take a look at one of the "household" type encyclopedias, it will explain the main ideas.

Also an old trick from the broadcasting industry: If you think some object might have errant electricity running around in just waiting for you to come along and serve as a path to ground, brush it with the BACK of your hand. That way, if there is some juice, your muscles will pull your arm back out of harm's way. Reaching out with an open hand in the normal manner can trap you if your fingers contract around whatever you touched. When ever I approach the old 'Silver Pullit' I brush the back of my hand against the trailer skin which reassures me that it is OK to grab the handle next to the door when I enter. It is a habit that also serves to remind me that electrical problems can occur, especially in campgrounds.

This whole thread was shocking to say the least.

Good info to have. I happen to live near three very significant power lines and from time to time any metal we touch when we are out back near them will give you a shock. The lesson I learned is to not park my trailer or cars too near the power lines. I don't know why it happens. Some people are so sensitive to it that the hairs on their arms stand up, others don't feel a thing.

A lot of it depends on what footwear they have on. Highly electrically isolated footwear makes your conductive body accumulate a charge. This charge can be measured with a static voltage meter.
