benwil lift model TPO#7
(OP)
this lift was wired for 440v I believe, it has a three wire
transform wired in on the control circuit (220v) with a toshiba motor for the hydraulic lift pump, the problem is the
motor data plate is written in a different language, and on the three wire transform the only thing I can think of is 440
on the two leg with a center tap for the 220V.
two reasons why I think it was wired for 440v 1. I pulled an air compressor out of the same building that was wired for 440v. 2. The motor is a 9 lead motor with three of the
leads 1.ea tied to the hot legs and two wire ea. wire nutted
for the other 6 leads. like a regular 9 lead motor with
1,2,3, tied to power and 1,7*2,8*3,9 tied together for high
voltage.
Thanks,

RE: benwil lift model TPO#7
Your assumptions sound reasonable.
When you try it on 440 volts, use fuses or a breaker close to the proper size.
Checking a motor when you are not sure of the voltage is NOT the time to use the great big spare breaker in the MCC because it's handy.

LOL
It's surprising how many people don't think that through very well before they try it.
