Thanks for the explanation, Dennis. Copper-clad aluminum is of course completely different than bare aluminum screwed to ordinary brass and steel outlets and switches, which quickly develop resistance and heat.

By using only species that do not grow too much or reproduce too freely, we ignore some of the most useful species. Thus the first priority in healthy broadacre farm landscapes, rangelands and forests must be vigorous and self-reproducing plants. -- David Holmgren :::: 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)
