Sub Panel

neutrals and grounding conductors can’t be under the same lug, then you are correct. :wink:

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.
