branch conduit penetration location in service

[djbasl]

I am trying to find in the 05' or 08' NEC where it talks about branch conduit penetrations in the service panel. I have alway's understood that you could not enter the service panel anywhere on either side of the panel where the bussing is located. that you could pentrate only on the lowest few inches of either side where the concentric/eccentric k.o's already are, and obviously the usual top and bottom of the panel.

No such rule in the NEC.

Maybe you're thinking of 230.7 which prohibits conductors other than service cables from being installed in the same service raceway or service cable?

r are you talking about a 3 r panel?

If the panelboard is within a cabinet, could you be speaking to 312.2(A) ('o5 code) regarding raceways entering above the level of uninsulated live parts? :smile:

Generally speaking you just have to maintain sufficient wire bending space if you're coming in the side. Also if it's an outdoor panel if you come in at a level above the busbars you have to have a weatherproof connection, meyer's hub or equiv.
