For you guys with equipment conversion experience..
E/C has a customer in an old facility with a 3 phase Oh O&H Crane.
The original service is long gone and a new 400 amp single phase 240/120 service was recently installed.
Now the customer wants to put the old Crane in service.
Largest motor is 10HP
Motor nameplates show 460/230 motors but from what little info was provided it looks like it was originally operated on 460.
POCO estimates cost for a new 460 service at $3 k
Best Route:
(a) Get 3 phase 480 service.
(b)Rotary Phase Converter
(c) Drive
(d) other ?
(e) run away
If he chooses (b)or (c) can either be obtained with 230 SP in and 460 3 phase out ?
