We are designing a machine for a customer who said they have:
240 vac / 120 vac
We need 3 phase for our machine.
I want to be sure they did not mean 208/120 wye so I went over to the plant.
3 Pole main / Nuetral bus / ground bus in panel OK
2nd pole had org tap OK probably center tap of delta but know high leg (208v)
239 V A-B
239 V B-C
239 V A-C
120 VAC A-N
120 VAC B-N
120 VAC C-N
Does anyone have experience with this type of system.
I left thinking we should be fine (not sure of how they were doing this) had 3 phases and 120 vac. I just had my Fluke meter and did not verify this was a true 3 phase system???
First post Thanks
