Tom, et al,
The service consists of a 320A disconnect (I think, maybe a 400A) feeding a 320A Meterbase (no CTs). This directly feeds a 75KVA Dry type Xformer that feeds a 225A 120/208 panel, which will be totally redone with the Xformer being fed from the new 480V power panel.
Not all the machines can run on 480V, the moulder will have to be 240V Three Phase with its own Xformer, I suppose.
Heck, just to run pipe and wire to these machines is going to be major, I really don't have the resources and he's offering "help"... (hoo boy -
smacking self in forehead)...
The layout will require a boom lift, sissors won't reach most of the places, specifically the switchgear area.
He'll be buying the materials, so I'll lose mark-up, and I'll end up doing the brain-work at an undetermined price (read > free)...
Yes this is beginning to smell of $1000 bills going up in smoke...
(post edit)
Oh yes, he claims very few, if any, machines will be running at the same time, but one good jolt of trying to meet some deadline will probably find the service to be inadequate. Then he'll be mad at me...
Conversely, if he never has a problem with my "over-designed" system, then this merely proves that it was unneccesary to make it so large...
I'm beginning to hate this business.
