Hey Guys...
I've got an upcoming project with a lumber mill (of sorts) that has moved to a building with an existing 480V Delta Service with three 50KVA cans, one per phase (obviously)...
The 480V goes Directly into a 75Kva Dry Type Xformer and gets converted to 120/208V Wye before going to a 225A three phase 120/208V panel.
There is no 480V Panelboard, of which I will have to add one...
Anyway...
In a nutshell, does three 50Kva cans give the same power as a single 150Kva can? In other words, can I get 180 Amperes at 480V outta this thing or just 60A?
The motor load is going to be HUGE.
Nameplates are largely unavailable, except on individual motors... Most are 460V or 230V, only a few are rated for 208V...
1> 40HP Blower
2> 10HP Blower
3> 5HP Tablesaw
4> 5HP Band Saw
5> 220V 3 Phase 145A Moulder
6> 5HP Router
7> 15HP Planer
8> 15HP Planer
9> 150HP Sander (not a typo) with 50HP Conveyor
10> 15HP Unknown Machine
11> 15HP Unknown Machine
12> 3HP Unknown Machine
13> 2HP Unknown Machine
14> Various Fractional HP tools and machines.
The Moulder will only operate on 220 3 phase... I asssume that 208 will not work and it will require a Xformer for 240V 3 Phase at 150A.
Just how big a service will they need?
Any and all help appreciated.
