Hi Lee, my point entirely because although most appliances are fully insulated from the end of the cable, a charger potentially has open cables which can track to earth when incorrectly handled.
Very high earth fault currents can be generated when there is a direct connection to the mains supply whereas an isolated supply is self limiting and ideally left floating in relation to earth. Switch mode (buck boost) power supplies reduce the isolating transformer to very compact sizes and I would seriously question the necessity for anyone to supply electronics which are not safe. -- View this message in context: http://electric-vehicle-discussion-list.413529.n4.nabble.com/100ah-pack-on-the-cheap-tp4663470p4663590.html Sent from the Electric Vehicle Discussion List mailing list archive at Nabble.com. _______________________________________________ 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)
