I need the code article covering the following senario.
Customers home has a panel that is heating up and burning the plastic insulator on the neutral bus. When I checked it out I found that the neutral conductor on the service entrance cable was terminated on the ground bus attached to the can. the neutral bus was then bonded via bond screw to the can, thus useing the can as the neutral conductor. The bond screw was slightly loose so the screw was carrying the unbalance load and arcing to the point of heating and burning. I replaced the panel guts and terminated the neutral on the neutral lug as it should be. problem solved. The home owner wants to pursue this with the inspection department as this installation passed final inspection. (new home) I for some reason cannot find the appropriate code article for this.
Thanks
