I will the describe the generator in FULL detail. It is a 3500 watt electric start generator, with 3000w "normal" output, 3500W peak output. The details are as follows:
--it has a switch to run the gen in either 120v or 240v mode
--it has a plug/receptical labelled 120V, normal 3 prong plug, with a 20 amp breaker
--it has a plug/receptical labelled 120v/240, 4 prong twist plug, with a 30 am breaker
The manual is VERY poor on description other than saying this, "both plugs may be used simoultaneously. If you maximize the first 120v receptacle you may use the second".
THAT is exactly what I would like to do...BUT...it is a 4 prong plug and all my extension cords are 3 prong, 15amp cords..all I want to do is figure out a way to use the 2nd addition plug and get around the darn 4 prong requirement..and i'm not sure if when I use the second plug if my switch should be in 120v or 240v position...since if I use the second plug at 120v, in addition to the first plug as 120V this really is 240V total!.
