Ground and neutral on same bus?

[DanielVetpath]

Electrician recently installed new service and breaker panel in my shop. I asked him to initially install one 220 and one 110v circuit. Removed the cover the other day and noticed he had run the ground and neutral to the same bus in the box for the 110v circuit. Is this acceptable/normal practice? All of the references I have been reading indicate neutral and ground on separate bus terminals. Is this simply to keep things organized but not really necessary? Thanks for any input.

Yep, electrically all the neutral busses are the same. I've had inspectors request that they be on separate busses, just in case, but there really is no need.

NEC refers to the neutral as " a grounded conductor".

they are together at the main panel.seperate at the sub panel.bond ground buss to box,isolate neutral from box at sub panel.if this is grom a whole new service,as in from pole to panel,it is ok.if it is feed from a main panel some where not correct.

In the main service entrance panel they are the same, in a 4 wire fed "sub" N and G are separate.

Thanks for all your input. This is a main panel - power running from transformer directly to this panel, so it must be okay.

i see the bond screw in that buss, but wheres the feeder's neutral? and wheres the GEC? something doesnt seem right. can you post a pic of the whole panel?

I will gladly post a new picture of the whole panel. I asked the electrician to install the new service and hook up one 110v and one 220v outlet to get me started. The 220v outlet was hooked up wrong - I didn't know enough at the time to understand what was wrong, but it must have been at the receptacle. I just know that it was arcing inside the breaker panel (where the conduit entered) everytime I would throw the breaker on and there was no power at the receptacle. They came back, mumbled a bit and now it is fine. This experience is what lead me to consider running conduit (paneled pole building) and doing the rest of the wiring myself. I will be out there later today and take a new pic. Thanks again for any input.

There may be another N buss.
