I just bought the Cosco "PowerWise" 3KW genset which schematic was posted by Alohatraveler on 05/02/06 09:21pm. So far it's working great! It has two independent windings as commented upon by Professor95 that are switch configured by a 4PDT (actually "3T" as it has a middle all off position) switch. I did some minor dissection of the wiring for inspection (pulled the outlet panel and pulled the generator back cover.)
One thing I noticed, and it is not shown in the schematic, is the bottom terminal of the top winding (white wire) is wired to chassis ground in the generator (not in the switch panel.) So neutral on the 120V outlets is shorted to chassis GND.
Also something that IS shown on the schematic is the "neutral" contact of the 240V twistlock connector is left unconnected. I found this a minor irritation.
One BIG irritation is I've not been able to find any real documentation of this product on the web. Not even a manual. And even though I bought it at Costco it is not listed on their web site. Even the PowerWise web site listed in the paper manual from the box has no information on this product!
