Continuity

[guschash]

I had to check some work being done at church, so I started at the lighting panel . It was being fed from QMB panel. So being fed from this QMB panel would make this a sub panel. So I had them remove the bar tiring together the neutral and ground bar. I check with my and I still had continuity between them. Is this right, I would expect them to be separate.

Assuming that the neutral was not bonded to the enclosure you will still read continuity between the EGC and the neutral because they're connected by the MBJ in the service.

If the neutral is bonded to enclosure , what problems will I run into. It was couple of days ago and I know checked but right now I can't remember what got. Why would they bond the neutral to the enclosure anyways.

How many conductors supplying the panel, and where is it located in relationship to the service,
Where is it being supplied from?

The neutral current will be travelling on the EGC. If there is a metallic raceway or cable used then the neutral current is present on them too.
