Odd Breaker Situation...
Odd Breaker Situation...
Changing out the cheapy light fixtures that came with the house, I turn the switch off, remove the old fixture, accidentally bump common (white) against frame (green) and breaker popped. Measure white with DMM... AC-level is a few hundred mV (noise?). Measure black with DMM... AC-level is even smaller. Likewise black to white. Touch black to green... nothing. Touch white to green... pop. Do these new breakers have the equivalent of GFCI built-in? ...Jim Thompson -- | James E.Thompson | mens | | Analog Innovations | et | | Analog/Mixed-Signal ASIC's and Discrete Systems | manus | | San Tan Valley, AZ 85142 Skype: skypeanalog | | | Voice480)460-2350 Fax: Available upon request | Brass Rat | | E-mail Icon at http://www.analog-innovations.com | 1962 | I love to cook with wine.

Sounds like something is wired wrong. It is also legal to use a white wire but mark it with black tape to use it as 'LINE' or HOT. CHeers |
