One panel in the garage

If the main disconnect is located in the garage and that is the only panel present, do the ground wires and neutral wires have to be separate? This panel looks very sloppy to me the way the ground and neutral wires are run to the buss. Some are sharing the same lug. How would you write this in the report?

Ground wires and neutral wires belong on separate buss bars-ground-neutral bond not visible at garag.jpg

Grounds can be ganged,
Neutrals cannot; they must terminate under their own individual terminal lug.

If this is the main then the two can land on the same bar.

What is do see wrong is the grounded (neutral) and equipment grounding conductors under the same screw

Does anyone see the main bonding jumper? I don’t see anything that is bonding the panel enclosure to the grounded (neutral) conductor.

There’s a green bonding screw…top right of the buss.

This’ll help…

Is the screw I have pointed to here the bonding screw?

It’s the one right above the one you’ve identified…

ditto - green hex head

That is what you call very sloppy? At the rist of sounding narcissistic mine are a bit neater but that looks fine to me.

I have to say, here in NY that method of terminating grounds and neutrals of the same circuit is generally accepted by inspectors and MANY quality electricians do it that way. I did for many years, but do not any more.
We do NOT follow the NEC and I have had high level inspectors tell me it’s fine.
Take that for what it’s worth.

Thanks for the help. So, this is alright? As long as there are not two neutral wires to one lug?


Document it.


P.S. Does anyone see a GEC? If it’s at the Disconnect, why is there bonding here?

That’s the only call out I see… “neutrals fail to terminate at their own termnal lug”

For the record: I understand the issue most folks have with this, but those photos are NOT the same thing. Doubling neutrals is not the same issue as in the original post.


Have to quote Petey :mrgreen:

Incorrectly spoken; ‘Neutrals not terminating beneath their own terminal lug’ is the call out.

They are not double lugged… Petey is correct, double lugged is different.

Yea now I see it. Guess I am so blind I need to be lead to the point before I know that I am there :mrgreen: :mrgreen:

Thanks. One more question…do you call it? I did call it but did once before only to have a licensed electrician say it was fine. What do you suggest?:mrgreen: </IMG>

Tell your client to request the same quality of service you provided, their (the electrician) opinion in writing.



The grounded and grounding conductors must be isolated from one another unless there are no continous metallic paths (conduit, equipment grounding conductor) between the main panel and the sub panel. If there is no continous metallic path, they must be connected together.

It is not allowable to put more than one conductor under a screw unless they terminals are specifically identified as being suitable for the purpose. It does not matter what the use of the conductors is. The same rule applies for grounded, grounding, and ungrounded conductors.

The connections in Mike Holt’s graphic are OK, not because they are grounded and grounding conductors but, because the terminals are rated for more than one conductor.

Conductors should not extend more than 1/4" beyond the terminal.


Grounds cannot be ganged together. This requirement has been under NEC Article 110.14(a) for as long as I can remember. I started as an apprentice electrician working under the 1971 NEC and that’s the way we were taught even then. It may have been in a different place in the NEC back then. I am almost certain that it has been in 110.14(a) at lease since the 1993 NEC.
