Jan, I agree entirely but yes, it is for real. Keep in mind that when using an inverter the ground to neutral tie is not present from the mains as you are disconnected from the mains. When the inverter is connected to the home / appliances it becomes the source of the relationship between gnd, neut, hot. We have tested numerous product and all of the less expensive stuff has the center tap output. We needed to instruct our manufacturers that the neutral / gnd tie has to be there, it is more expensive to manufacture, not sure why.

This is rather hard to understand. It would be a clear violation of the electrical code, and would result in a breaker trip if anything was plugged in that had ground tied to neutral, which could very well happen. (Ground and neutral are supposed to be at the same potential.) :::: Entirely new ways of living are necessary, and if we don't adobt them voluntarily, we or our children will eventually adopt them involuntarily, and probably with great pain and difficulty in the process. -- Thom Hartmann :::: Jan Steinman, EcoReality Co-op :::: _______________________________________________ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org For EV drag racing discussion, please use NEDRA (http://groups.yahoo.com/group/NEDRA) _______________________________________________ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org For EV drag racing discussion, please use NEDRA (http://groups.yahoo.com/group/NEDRA)
