Hi all,

I do have a Distribution Panel With 8 branch circuit breakers (hree phase) whith rate 160 Ampere & 220/110 Volt so I would like to connect two circuit breakers from Distribution Panel to feed one panelboard with rate of 400 Ampere?
So is it possible to have two circuit breakers (6 pole) connect to one panel board?


thanks a lot
 
Not allowed. 240.8 limits circuit breakers from being connected in parallel other than listed factory assembled units.

Yes, it is possible. You can also step into the path of a freight train.

Should you? Absolutely not.

Ref: NEC 240.8
 
Is this a project at your own home, or something to do with a work-related installation?
