The main LT board. Everything downstream of the transformer starts here, so it carries the highest current and the tightest separation.

A PCC sits directly on the transformer or generator secondary and feeds every other board in the building. Because it carries full fault current, the busbar bracing and the compartment separation matter more than the feeder count.
Form 3b keeps busbars separated from functional units and terminals separated from each other. Form 4 goes further and separates each terminal from its neighbours, which is what lets an electrician work one feeder live.
The assembly is ours; the switchgear inside it is genuine, authorised-channel product from the makes you specify.
Built to the same standard, and able to share a lineup with this one.

MCC · 4000 A · Draw-out

PMCC · Combined

8000 A · Dual bus
A drawing, a load list or a BOQ is enough to start. You'll get the ratings checked against the actual fault level, a general-arrangement drawing to approve, and a fixed price.
