Mobile system grounding [RE-wrenches]

[Jeffrey Wolfe, Global Resources]

Hi All,

We have our mobile trailer. Yes, we drive a ground rod EVERY time we use 
it. We've developed an unsatisfactory system for pulling the ground rod, 
but haven't lost one yet.

I think what Gary is talking about is GFI outlets, not PVGFP. The GFI 
outlets are a good idea. If you're at any fairs, and many other events, the 
trailer electrical will be site inspected. They'll be looking for some form 
of GFI protection on any extension cord, etc., and this is the easiest way 
to do it. We mounted some duplex (non-GFI) receptacles inside the trailer, 
and put two duplexes in a WP box outside, each GFI on a different circuit.

We also put a pipe nipple through the side of the trailer to run the ground 
out. This way, we can hook it up, and close the doors and lock it up while 
it's operation. Means we don't need to stand around and protect it from 
fiddling fingers while we power Ben & Jerry's!

Jeff

Do you realize you'll have to drive a ground rod every time you park it?
Why the PVGFP?  If no one is sleeping in the unit then PVGFP is not 
required
(the way I interpret code).
