Hoist Data

[Alwayslearningelec]

Don't have hoist data sheet but I'm going to feed it with 200A at 480v. Have a 120/277v source so will need step up xfmr.

Seems pretty obvious but looks like need 225kva xfrm to deliver proper power to hoist, correct?

I think that your power source is 208Y/120 not 120/277?

That data sheet is for a step down transformer, and while you can reverse wire it, it would be better if you get a step up transformer. If you use the one on the sheet, you will have to run the 480 volt secondary as a ungrounded system requiring ground detectors or as a corner grounded system.

As Don stated you're better off using the correct Delta/Wye step up transformer. I believe that some of these hoists have a VFD which may not like the corner grounded system.
