Since the ground wire doesn't carry any current, there's no voltage drop, and any metal housings connected to it are truly at ground potential. The same cannot be said for the neutral wire, especailly at the end of a lengthy wiring run or long extension cord. -Phil ---------- End of Message ---------- You can view the post on-line at: http://forums.parallax.com/forums/default.aspx?f=7&p=1&m=268433#m268640 Need assistance?
