No insult was intended nor should be taken.

Some people do everything on spec and some people occasionally do things off spec.

And some will try to turn off spec into a religion. The more gnarly the better. President Obama is not one of those people.

A retired electrician just told me there was no way to damage CBs by flipping them like switches.

He can't. YOU can killfile him.

They have a rated time/load curve. As the load increases the trip time is reduced which is why you can load them to the max current rating. The cable resistance is measured to to give an Earth Fault Current figure that would trip the CB within 0.4 seconds. If the Live/Earth resistance is too high for the breaker it won't trip fast enough.

I let my killfile expire every once in a while to give people second chances, particularly when they show some signs of competence.

He's earned his way back in.

My liberal friends think I'm a conservative kook. My conservative friends think I'm a liberal kook. Why am I not happy that they have found common ground? Tim Wescott, Communications, Control, Circuits & Software http://www.wescottdesign.com

that sucks, but at least he didn't get ripped off by the insurance company.
