NEUTRAL and ground together in sub panel

[JAMES DAVIS]

When is it ok to put ground and neutrel on same bus bar.

[Robert Meier]

If the panel was located at a separate structure and they were under the 2005 (I believe) or earlier versions of the NEC.

... and there are no other metallic paths (connections) between the structures, i.e. metal conduit, metal piping, cables/low voltage wiring, fencing, etc.

Yes that's true. I was focusing on the requirement applying to separate structures. If the structures are not separate then I don't think that it was ever permitted.

A difficult thing to determine during a home inspection, so refer it to a sparky.

That has always been my position as an inspector.

In any enclosure that contains the service disconnect is the only place where this is permitted except in earlier editions of the NEC where a remote building is supplied by a three wire feeder and another grounding electrode system is established.

Thank you , Mr Whitt. I have one more question, this remote well I am hooking up is a 3 wire connection and I was wondering if I could use a single pole 120/230 breaker.

Is this a home project or is it related to an inspection?

[JAMES DAVIS]

It is an inspection,thank you.

[Jim Port]

A single pole breaker will only supply 120, not 240.

A tandem will allow two circuits of 120.

Good to know and note taken.
My weakest subject for now.

Why do they sell a single pole 120/230 breaker if it cant do what it says:

Not sure I understand, where are you finding a 120/230 volt circuit breaker? If anything a slash rated breaker would be 120/240 not 230.

James you said this

Ask your self, where would I connect 3 wires at a panel with a single pole breaker?
