I still remember the first compact fluorescent light bulbs I bought back in '95 or '96. I brought them home, screwed them in and found out that I didn't particularly like them because of the strobe effect that these lights created. In fact, I considered this effect so irritating ...

In the standard 60cycle 240V 3 wire feed from the pole to a house or small business I've noticed that the neutral wire is sometimes smaller than the two hot wires. Why is that? Has the assumption been made that 1/2 or more of the load will be from 240V devices that don't use the ...

Cross Country Faults?	26 Feb 2004 10:02 GMT	4
I have been exposed recently to a Schweitzer that provides protection for what is called "Cross-country Faults". If I've been told the truth, this would be for when there are two circuits on the same double circuit tower, and the wind gets high enough to let both conductors of ...
