Help on a 30 amp RV plug

[Bamarickandlisa]

The ground and neutral are together in the box that I'm hooking up my 30 amp rv plug.
Do I need to get a new box that has a separate ground or is it a way to hook the RV plug up? 120v with 30 amp braker !!!

Thanks

I think what everyone is trying to say is: Both the neutral (white) and the ground (bare) should be separate wires all the way back to the house circuit breaker box. There, the neutrals go to one bus bar, and the grounds go to another. It is in that box, however, that the two are generally (according to code) tied together. Even if they share the same bar, the whites and the bares are separate all the way back to the box. The reasons why are buried in codes and ancient history. What's important to you is black (hot) is all by itself, and you have two parallel paths back to the ground/neutral bus bar.

I have no idea what a "ground buster" is and I'm a licensed electrical contractor. Codes change and wiring schemes are different. This same thing got drawn out forever a few months back.
Without getting into all the various code reasons and wiring scenarios it may or may not be correct for the grounds and neutrals to be bonded together in your garage panel. Either way, you can certainly hook up an RV outlet. You would put both the ground and neutral from the RV outlet onto the bar.

Yes

But....

If the box in your shop is a sub-panel off a main box it should have a "ground buster" installed so the neutral and ground are separated.

In your house breaker box, the ground and neutral should be bonded. Not in the RV.

At my house, which is wired long ago, all the ground and neutrals come together. They should be separate, but doesn't need to be.

Should be separate.

The shore power can plug into a receptacle that has the neutral and ground connected together.
The box in the RV must have the ground and neutral separate.
