Common wisdom puts a pack fuse in the battery box before cables exit, so no matter where they are shorted, the fuse blows instead of creating a plasma ball. Not all DiY builders follow this practice - or even official converters. My EV that was converted around 1995 by a now defunct converter company, has no overcurrent protection on the battery pack (under the bed of the pickup) before it hits the dual breaker near the grille, in the very front of the car. Quality cable is used and it is routed and tightened well, but any event that would create a short anywhere along the many feet of pack cabling, would cause a current only limited by the battery pack itself. Indeed, I still need to buy and install a fuse inline in the pack.

I definitely agree that you want to keep positive and negative in the same conduit. My concern is that with thermoplastic insulation and no fuse, melting insulation could be a major disaster. But mechanical compromise (like high-centering) could be just as disastrous. Thus my suggestion to run wires together that were at similar potential, so you wouldn't have vast fault currents flowing in the event of insulation failure. :::: Traditional grass-based dairy farming was a highly egalitarian enterprise; anyone with initiative and a few acres could herd animals on any kind of land, and sell or barter the products to his neighbors. Societies that consume the products of pastured animals are much less likely to exhibit huge disparities in wealth compared to societies where the economics of food are based on grain. -- Ron Schmid :::: 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)
