120 VS 220 VAC
« on: May 21, 2008, 02:09:49 PM »
I have a Metro / indian made 4kVA generator head that came wired for 220 VAC split phase.  Since i only have 120 VAC loads on my backup load center (this is only for backup use not daily running)  i would like to re-wire the gen head for 120 so I don't have to deal with the issue of balancing the loads.  Does anyone here done this?  I do not have a wiring diagram for this head.

Thanks Carl

If you 4 slip rings its easy.
If you have 3 its not possible see transformer threads for other options

doug,

Thanks for the reply, the gen head only has 3 slip rings so it's not worth it for me to go the transformer route.  Since this is only for backup use and the load is never really that large anyway i will just keep it at 220 Vac.

Thanks
