the fuse box to power it if i up the amps of one breaker. the machine has a control box with a soft start in it.

this is a copy and paste of one of the machine specs
ONE - Floor standing, mild steel Rittal type IP54 enclosure having control circuits to feed a 160kW. Motor.
The approximate overall dimensions would be 1000m.m. Wide x 2100m.m. High
x 600m.m. Deep. The enclosure would have adequate ventilation fans
rated in line with the ABB requirements.
The following items are included:-
1 - Main incoming 160kW. fused switch type ABB complete with door
interlocked padlockable handle and high speed fuses.
1 - 160kW. Triple pole main contactor with 110V coil.
1 - 380/110V Control transformer.
1 - Set of control circuit breakers.
1 - Thermistor relay.
1 - Set of interface relays.

Yeah in short.
For things of that loading I use boards like this:
that take breakers that look similar to this:
Or feed direct off our 1600A busbar.
You will need the incomer to the building removed to do it so yeah it will prob cost a bit. Sorry I can't even guess at a price as I'm not
self employed/contracting.
