Subject - NEUTRAL BAR NOT BONDED
GunbossCSG6 I am doing some addditional wiring on a house that a small fire from a Christmas tree.

The main distribution panel was undamaged and is a 200 amp Murray brand. The equipment grounding bar and the nuetral bar were not bonded together. Additionally the nuetral bar itself was mounted on plastic and isolated from the metal panel.

There was a MBJ installed which bonded the main distribution panel to the equipment grounding bar. There was an "L" shaped bar of copper mounted to the bonding strip that went to the equipment grounding bonding strap across the back of the panel. This bar can be positioned (rotated) to make contact with the nuetral bar and effectively bond it to the grounding bar through the bonding strip across the back of the panel.



With the nuetral bar not bonded to the grounding bar, what type of problems could occurr? The home owners complained of outside lights requiring frequent light bulb replacement and the GFCI in the garge constantly tripped while supplying outside loads.

Comments appreciated.
Electricman Is this panel the main point of disconnect? You have described a sub panel where the neutral and ground shall not be bonded together.

The panel I am referring to is the MAIN panel with the service entrance conductors.
Electricman Neutral and Ground should be bonded in main disconnect panelboard.
JimmyDee Trying to picture a Murry panel, if I remember correctly the ground bar is screwed to the metal panel box. That effectually would bond the ground terminal to the box and if the main bonding jumper is installed correctly, the neutral is effectually bonded to the panel. The two bars would meet the criteria for being bonded together. I think it is OK.
