I have a question about the smaller ground buss at the back. Wouldn't it have made for a "cleaner" installation if the ends of the ground wires were cut off close to the point where they extend past the buss screw? Wire ends are kinda sharp and could bite into the insulation of the black ungrounded conductors.
Since this panel has a separate ground buss, could this panel possibly be used in a mobile home?
Thanks for your kind words of welcome!!

Hi, Scott. I absolutely agree with you about using the lower buss first. I guess it's more a matter of courtesy than anything else.
It seems that an electrical panel is always a "work in progress".

Joe,
I have been failing jobs for this under 110-3. The job has to be installed as per the manufactures instructions. Most manufactures only allow 1 neutral wire per terminal. I am glad that it is finally written under another code section that can be written up for. I once looked inside an old service panel and wondered who left a small red light on inside this panel. Imagine my surprise when I found out that the red light was really a neutral conductor glowing red hot. It was doubled up under a scrw terminal and they were both very loose.

I dont buy that argument. One neutral could be just as loose as two. Many manufacturers now allow you two terminate two, and some three, conductors under one terminal. In my 15 years in the business I have not seen one problem caused by more than one conductor under a terminal. I challenge the powers that be to actually count the termination points in a panel.

Are you sure? Are you thinking about the equipment grounding conductors? Please open the door on a panelboard and see where not more than one "grounded conductor (neutral is permitted to be terminated under one screw on any grounded conductor terminal bar.
I agree with Harold 100%

Scott,
The UL product standard for panelborads has not permitted more than one neutral under a single screw for a long time. It does still permit in some cases more than one EGC under the same screw, but not neutrals. The rule has been enforcable under 110-3(B) but was added in Article 408 to make it very clear and to make sure that more installers are aware of the requirement.
