hours on generator



You are correct you can use it in 120/208 3 phase mode to run your home. Using 2 legs of the 3 phase will supply you with 2, 120 volt to ground legs and a 208 volt phase to phase voltage.

However you will loose more than a "bit" or the available power of the set. Running it like that, you will loose probably close to 1/2 of the capacity of the set. Also, the unbalanced loading of the set and prolonged use like that could eventually damage the generator portion. As far as running your household appliances on 208, yes most are rated to run at either 208 or 240 volts. However, if your appliance has a control transformer in it, like your furnace or air conditioner, it will probably not work if you do not re-wire the control transformer for the new 208 voltage. You will not have enough voltage for the controls without re-wiring it. And if you do re-wire it and forget to put it back when utility power comes back you are asking for more troubles with over-voltage on the controls.

All of that being said, for the average homeowner, that is a bit much to SAFELY undertake. And with a price tag of just under $. I think I would not buy it and keep my eye out for a nice MEP-003a or MEP-002a. Unless like I said, he just want's if for the engine.

Just my


swbradley,

That is a good effective way to generate your own 3 phase...we always called it "pirating" 3 phase. You do get quite a lot of loss making a phase converter from a 3 phase motor. But is it cheap and effective; and you gotta love that especially if you can get a large 3 phase motor like that cheap, or better yet, free.
