main LVAC panelboard

[144x]

in a project the manufacturer of the LVAC panelboard has used continuous busbars in suite of 3 panels so the panels have to move together .he has also used cable in some part of the panel instead of busbars .is there any specific recommendation in standard to prohibit these design.
thanx.

Nope. NEC restricts you to a maximum 42 poles on branch circuit panels. That's about the only limit I'm aware of. On power distribution panels, the sky's the limit, and cable inside a panel is no problem.
