I am considering buying a used BP 1993 series II manual mill that in
the ad lists it as being 480v 3 phase, but my building just has 208v 3
phase power. Do these BPs customarily come with transformers with taps
so I can wire it to run off 208v 3p, or am I stuck having to buy a step
up tranformer to create 480v 3p for it?
I checked and a suitable new step up Square D transformer costs $4k,
but I see one on ebay for $275, so I guess I can go that way if need
be. I see lots of step down transformers on ebay, for 480 to 208 3p.
Can I use one of those if I hook it up backwards? I've done that with
low voltage bf, but never with big 3p power, so I thought I should
will BP series II manual mill run on 208 3p?
