| The unit was put in 30 years ago for a hog operation and run
on single phase, even though the yard now is 3 phase. The yard is
split with 2- 200Amp services as I only have a 200 amp transfer.
All grain drying is on the other 200amp service. The unit is a AC
series 4 which means it has to be run up before load is applied.
At that time they also had a series 3 which had an added
permanent magnet stator so unit could start under load.
That unit was mounted outboard of the back bearing.
but wasn't very big
While I had the barn I would convert it to 480 3phase
to run a 15HP pit pump a couple of times a year.
The generator is now also Perkins powered. It started out
as gas, but about 4 years ago I changed it over to 354
Perkins. With the gas we now have, it as a constant battle
to keep the carb clean.
I attached some information on twist locks. If they where
properly installed , just looking at the plug will tell
you phases voltages and amps. pictures are not that good
as a got information a few years ago and keep record on
computer. It is a lot easier to find that the paper.
