Hey guys, could use some help on a transformer question. I just picked up a Monarch series 62 Dyna-shift tracer lathe. While I was attaching the wiring to the disconnect I noticed there was no way the #4 wire I had run would fit in the connectors. I knew that was the correct size for the 20hp motor on the machine so was stumped for a second then realized the machine was set up for 480v.
Everything in the cabinet and the main motor are 240v/480v so I figured no big deal. Then I started looking at all the I believe they are called heaters and other stuff in the cabinet that had amp ratings and it was all ok for 480v but not rated high enough to switch to 240v. It was like 25hp at 480v but only 15hp at 240v.
So I have read on here that trying to over current those is obviously bad and all the wiring and everything is too small for 240v current.
So I am guessing the easiest thing to do is get a step up transformer from 240v to 480v. The rating on the motor is 24.7 amp at 480v and there is a little 1hp hydraulic pump for the tracer but that is about it for load. Not a lot of electrical stuff on this machine.
TLDR:
Any recommendations on what transformer to get to step 3 phase 240v to 480v with a 25 amp load (20hp motor).
Thanks guys.
