Re: Buying My SKOOLIE Soon - Need Help On Wiring!

when a 110v elect panel is attached to something like a wall, the panel skin itself is thus grounded to the chassis. most people don't realize that when installing the panel.
a fiberglass bus, panel would be isolated of course.

i have just wired every one of mine like the new mobile home code for the last 25 or so years. and always properly test it to make sure there is no current flow at any time to actual ground... like if its raining outside.
think my newest nec book is something like 2006...

always put gfi curcuit or recepticles near water of course.

That's true, but I'm wondering if that's required or even wise? I've seen many RV AC breaker boxes attached to plywood which would give no chassis grounding at all. Do the Oregon rules specifically require a ground connection between the RV AC panel ground bar and the chassis or does it simply require that the RV panel is grounded to the shore power panel by a dedicated ground wire?

The second method would be just like adding a sub panel (also called a main lug panel) to a house. You wire it the same as the main panel except that the neutral bar (where the white wires attach) and the ground bar (where the green or bare wires attach) are separated on the sub panel. On the main panel both the neutral and ground wires attach to the same bar.

Dear Cal, I apparently am unable to express myself very well. So I will simply keep my "ridiculous" statements to myself.

BTW, Our first house that burned to the ground (electrical fire) was wired up by a licensed electrician.... one with a drinking problem. We learned that as we were standing looking at the ashes of our former home.

I think I will carefully choose what I post from now on, I'm getting a little tired of being attacked.

First, I am sorry about your house.

Second, I was not attacking you. You made a statement that I felt a need to respond to. This is a forum where discussions take place. Anything said can be challenged. It even happens to me but not very often because I know everything. Haha. You make it sound like most electricians are inept. I don't think that is the case. I also don't think a chassis is grounded on 120AC. If I am wrong, so be it and I will admit it.

THE ONE THING FOR CERTAIN IS A BEGINNER HAS NO BUSINESS WIRING THEIR BUS FOR AC. There are no take backs when you fry yourself.

Re: Buying My SKOOLIE Soon - Need Help On Wiring!

I believe that there is a lot of "mis" worded things out there.
If you have a small generator and plug an extension cord into it and then plug say 3 things into it,the circuit is completed thru the wiring correct?the appliances are not seperatly grounded,so an inverter works the same way on the ac side.
So if the "shore" outlet is properly grounded(easily checked w/a ...well checker thingie that lights up when its right
Then plugging in to shore would be like having a big extension cord powering the bus with seperate breakers of course)
So this makes it seem like no part of the ac wiring should be touching or connected to the bus

So what am I "missing"?

As long as no short between power/nuetral or ground happens then all is good,which is why gfi's are needed near sources where water can "complete" a circiut thus,...well frying you

Please explain this if I am thinking wrong

This is what I am thinking. If an appliance has faulty wiring or malfunctions and the only way for it to reach ground is through you because you are leaning on the wall of the bus, then what?

If there are any electricians in the audience, please help us. Lord knows we need it.

Re: Buying My SKOOLIE Soon - Need Help On Wiring!

I just looked at some RV sites and the word there is that the RV frame should always be connected to the AC panel's ground bar.

On the other hand, the frame should NEVER be conneccted to the panel's neutral bar.
