The power into your house is on 2 different circuits. One is 180 degrees out of phase from the other thus creating your 220v circuits. It's possible for one phase to go out and not the other. Ever have a power failure where only half of the lights in your house go out? I was an operator once for a UNISYS 9030. One day the CPU stopped, but the lights and the disk drives kept working and the tape drives were out. We had lost half of our 220v circuit. Took a while to convince the DP manager that we had power problems. _______________________________________________ TCLUG Mailing List - Minneapolis/St. Paul, Minnesota http://www.mn-linux.org tclug-list at mn-linux.org https://mailman.real-time.com/mailman/listinfo/tclug-list
