Hi Bob and all,

Have you checked the frequency of the voltage that the generator is 
supplying? I have a reed meter that is plugged into my generator which is 
actually a Lincoln AC - DC Arc welder which is also a 6kw generator.  I set 
my speed to make the 60 cycle happy. The voltage is normally around 115 plus 
or minus a couple of volts.

I run our well, furnace and a couple of circuits in the house with it.

There are a number of power panels that will let you take selected circuits 
from your switch panel and make them available to be supplied from the 
generator. This is basically a two way switch that will let you select from 
the main power source or the generator. Before I installed this I asked the 
local power company to check it out. They gave it their blessing as there 
was no way to feed back power to the grid.
