I am curious to know what bus material the panels you most frequently install have. Copper, Aluminum or plated Copper? I know that location plays in to this selection sometimes, but if it doesn't, why do you prefer what you prefer?

Copper, We use the CH Classic Loadcenters, We just use, good quality material on all our jobs, better contact with copper, and the breakers are better quality.
We tried other Loadcenters, and after problems, and expensive call backs we went back to CH.
SQ D is another good Loadcenter, but we can't use it on service upgrades where they are bottom feed, because SQ D has neutral bars all clustered next to Main Breaker, and all the neutral wires would have to be spliced to reach the bars.

LK, you could turn the SQ D panel upside down. Also there is no reason you can't splice the neutrals. I usually use Siemens for no special reason other than thats what my main supplier carries. I could not even tell you what the bus is made from.

We only have one supply house in town and they carry Siemens ITE. They have their stock loadcenters in either copper or aluminum bus. If you order tubs with interiors that take bolt-ins they are usually plated copper bus. I started dealing with a supply house in a neighboring town last year that carries GE Powerline Gold Series loadcenters. They come standard with tin plated copper bus, even the stab-in loadcenters. SQD QO loadcenters are all plated copper bus. SQD Homeline are aluminum only. I prefer copper and in situations where the loadcenter is in an unheated area, I prefer the plated copper bus.

When you turn the SQ D upside down, the neutral bars are at the bottom of the panel,
and yes there is a reason we can't splice the neutrals, the inspectors in this area, will accept, one or maby two splices, and that is it, all other splices they want in boxes outside the panel, also you can't get away with running the lines from bottom to top of loadcenter breaker, it will fail for loadcenter not to be used as raceway, we argued this was not in the code and the inspector said you are right, it is in the manufacture instructions, do it right and i will be back.

Say LK, I'm lost on how that inspector is calling the panel a raceway because you ran the conductors from the bottom of the panel to the terminations at the top. Seems to me the same would apply with branch circuits entering at the bottom and running to a top breaker. I would be willing to bet that the manuf meaning is to not allow conductors to run through the panel without terminating. As to limiting the number of splices in a panel, it must be an opinion of the local inspector. Do they have a written ordinance requiring this or does each electrician find out the hard way? Makes for a lot of extra work.

Norstarr,

Yes thst was my understanding of the manufacture, they say gutter and i belive they mean riser feeds, however more then one inspector has knocked this method down, good topic to bring to inspector site.
As for the splicing in the panel, most inspectors in my area will let one or two get by.

FYI, Square D has a "remodel" panel with a built-in splice block for splicing all those pesky wires that end up too short when you replace a panel. I wonder what your inspector whould think about that??

LK I'll count this as another misguided inspector. [Linked Image]
