Need some help/guidance on 400A distribution board

[davesparks]

Yes the acti 9 boards are all built with 200A busbars (might even be 250A) you just select the relevant incomer for your needs.
Above 125A the incomers come with an extension enclosure and the necessary interconnect busbar.

I put in a 250A Dorman Smith board a few weeks ago, but I think the highest MCB is 63A

Yeah they are 250A and you can have a 250A switch disconnecte on an expansion box

Don't want to be using Acti9 or any other mcb board for distribution you need a mccb panelboard.
