We had a power outage in the machine room at my shop. At first we thought it was a UPS failure. We rerouted all of the power around this UPS. Then we noticed this power connector which connects the UPS to a dedicated circuit providing power to the machine room: http://ultraviolet.org/photo-album/burned-power-connector Lucky we didn't burn the place down.
According to my quick research, the contact that burned up was the "White" lead, the power neutral. For what that is worth. < http://www.stayonline.com/detail.aspx?ID=6796 > Is this connected to an always-on-line UPS that continuously runs its inverter from the battery and charges the battery when AC line input is available? Just curious. That would make it a negative-resistance device, such that a reduction of input voltage (due to a bad connection) would cause more current to be drawn, to keep the power constant. Real positive feedback in the classical sense. carl -- carl lowenstein marine physical lab u.c. san diego [EMAIL PROTECTED] -- [email protected] http://www.kernel-panic.org/cgi-bin/mailman/listinfo/kplug-list
