Re: Huh?

Only if you'd asked the sparky to put them in the build.

Big 3-phase boxes I've worked with just have the output feed. Local power regulations generally decide what has to happen next. (with a splash of management penny pinching).

I've specced breakers per phase per rack with resulting impressively large power panels at the end of each row to allow for future maintenance.
