I'm going to be wiring a small cabinet shop, with new 120/208 service. All of the big equipment is rated 230v....
CNC machine 3ph 30a + 1ph 20a
Edge bander 3ph 30a
Table saw 1 ph 30a
Shaper 3ph 20a
Belt sander 3ph 30a
Dust collector 3ph 30a
Vacuum pump 1ph 30a
Air compressor 1ph 30a
The CNC manufacturer has suggested buck boost transformer. They said their machine doesn't really like 208 volts. I know motors don't like under voltage, so my question is about all of the other equipment. Think it's best to run all of it at 230-240 volts?
Then that got me thinking. Rather than sprinkling 14 buck/boost transformers throughout the place, it would probably be better to just set a 50 kVA transformer on the floor and feed up to a separate panel for all of that equipment.
Buck/boost transformers look like about $400 each, which would total about $6,000
The 50 KVA transformer is about $7,500 but probably a lot less work and definitely a lot less clutter.
I feel like I may have written out the obvious answer. But what do you think?
