That was one of the first things I saw, hopefully all the neutral on the right dont exceed the amp rating of that jumper...

Look close at the right side of picture. Underneath the 4th neutral from the

top. There is a flat bond strap. Hard to see on the left due to glare. Who

knows what his reason was for installing the 12 AWG ?? jumper was.

Yes the two neutral bars are connected by a flat piece of bus which is slightly obscured by the flash of the camera on the left side.

Yup Didnt see that...thanks Rob.. Whats with the No grounds, I m guessing he was one of those guys that thought they served no purpose.

Those are all AC cables, including the feeder, which have no wire type EGC's.

Yeah well I think it is a bad idea. You are now paralleling the neutral current from the right bar to the Grounded conductor, split between the buss and the wire. Beside this being, IMHO, a violation I think it very likely that the current on the little wire will exceed it's ampacity.

With the Flat Bonding strap being used, there could be current on the metal cabinet.

Thats a great point!!

Not could be, there is current flowing on the cabinet, on the cable sheaths, on anything else that is conductive and in contact with any of these, or connected to the equipment ground at outlets.

The current on the little wire will be net unbalance of circuits on the right side since they are all terminated on that side. (assuming no other parallel path, such as the bonding bar that is there) If all the circuits were the same amount of current the imbalance would be zero. It is pretty likely that the circuits are balanced in most cases, but we really do not know what the loads are either.
