Ya know, you are correct. Making the earth ground and the neutral independent isn't really possible, unless you want a floating neutral. I like the 220 solution, no GFI no problem.

If the neutral conductor is connected to the ground bus, which is required by the National Electric Code I believe, it will cause the GFCI breaker in the generator to trip. In order for a GFCI to detect a ground fault the neutral conductor on the load side of the breaker must be independent of the ground conductor. I don't know a good (safe) way to get around this. I'll have to think about it.

This year hurricane season is here so I pulled out my "new" generator (a used 6K generator my father traded me for a 10K generator I bought for him) and fired it up. It is running fine so I killed my main breaker and all the other breakers and tried to back feed into the house through the two electrical outlets I have always used. Here is what I see: 1) As soon as I plug the generator into the house outlet the GFCI on the generator trips. 2) Plugging two refrigerators into one of my extension cords (without the double male patch) works fine. 3) Plugging the double male patch into my extension cord and back feeding a power strip works fine (power from the generator coming into one of the strip outlets - the male cord on the outlet just laying on the ground). Any ideas? It looks like to me that both my generator and extension cords with double male ends are working fine. I've tried to plug into a house outlet (all breakers still off) in several different rooms and it trips the GFCI every time. I am confused since this is something I have done many times before with another generator. -- Robert McElwee and Blue Flash "The 50 MPG Miata" www.lightweightmiata.com/mpg Lightweight Miata Forum: www.lightweightmiata.com/forum The Miata Trailer Project: www.lightweightmiata.com/trailer ---------------------------------------------------------------------------- _______________________________________________ Miatapower mailing list [email protected] http://list.miatapower.net/cgi-bin/mailman/listinfo/miatapower -------------------------------------------------------------------------- -- No virus found in this incoming message.
