    I have been looking at a 320 amp pedistal main with 2 200 amp breakers.
    Can I get one that will take 4 breakers 2 200 amp 2 150 amp?
    Thnking of installing the pedistal on utiliity pole and then underground to branches. 3 buildings 1 corn drying station. No milking cows on farm. It is now and has been operating on 200 amp with a lot of 200 amp bugging going on. Not quality work!
    Any other sugestions are welcome. Little experence with branch curcuits like this.

    Cannot load a 320 amp service with 2-200 and 2-150 amp breakers, the max I have seen is 2- 200 amp.

    All feeders from the meter pedestal with main breakers need to be 4 wire.

    Ground rods are needed to ground the equipment ground bar at each separate building/panel. Keep neutrals separate from equipment grounding.
