Sub Panel

This is what I tried to explain in my last post.

But that's what I'm saying, I don't see the ground bar in that sub panel.

By doing this you are feeding a circuit from the sub panel that goes somewhere into your house from the main distribution panel. You cannot use the main distribution panel as a junction box. Put the circuit straight into the sub panel even if you have to extend the cable with using a small junction box.

Michael, where did you get this info? I do not believe this is a violation, at least in the U.S.

Canadian Electrical Code

12-3034 - Wiring Space Enclosures

Enclosures for overcurrent devices, controllers, and externally operated switches shall not be used as junction boxes, troughs, or raceways for conductor feeding through to another apparatus.

Well you're right, this is a Canadian code.

Hi John,

I know, I just wanted to re-interate on the fact that grounds from the circuits in the main distribution panel never touch neutrals either.

So almost all of the panels I've seen here in this forum thus far have the circuit grounds wired to the neutral bar screws and they're not correctly wired.

If you are trying to say that the neutrals and grounding conductors can't be on the same bar in the main dist. panel, you are incorrect. In the States, anyway. If you are trying to say that the neutrals and grounding conductors can't be under the same lug, then you are correct. I'm just a little confused on how you worded your statement.

I did mean it the other way too, they should be separated by a bonding jumper if the panel is the main disconnecting means in the service entrance (no disconnect ahead). So if this is your practice in the US then I'm wrong here but theoretically when it comes to bonding and grounding methods I'm not.

The other thing that as Mike did expain here in the USA for all subpanels useage the netral and ground must be seperated.

I know it kinda common mistake I did ran into more than once some case some peoples don't relized the code are allready written in there.

Quick call to electrician will take care the issue there.

Merci,Marc
