Isn't "Jamie" trying to say, "I am so ignorant I might as well be dead" ?:-) ...Jim Thompson

Who do you think you are kidding, i can't create or handle a 70 megatesla field. But i bet jamie thinks he can.

So, you are not an engineer, and arrogantly stupid, and listen to arrogant stupids as well. Reread the portions of the NEC that have been pointed out to you by others.=20

Jamie is an electrician, and not a very good one.

Excuse Me?

Sorry, there is no excuse for you.

Thanks. :-)

I have worked with engineers, technicians, electricians and many other trades people of all grades for some decades. I calls 'em as i sees 'em.

Because it interrupts the circuit when there is a ground fault, namely a path to ground that shouldn't be there and might be somebody's body.

No. The hot and neutral both run through a torroidal current transformer. If the outgoing and return currents don't cancel to within some small number of mA, there must be current leaking from one or the other conductor to ground, a voltage is induced into the CT sense circuit, and it trips.

A GFCI will work fine when a 2-wire appliance, like a lamp, is plugged into it. You can also install a GFCI-type outlet in an old box that has no ground available.

John

yes, arc fault, that is not ground fault..

Are you competing with AlwaysWrong in being always wrong?

John

John, you are arguing with an ignorant troll. In another thread he bragged about reusing so NEMA rated outlets at higher voltages where he supposedly works, then laughed and claimed they wouldn't pay for damages when some contractor's equipment would get damaged. He won't even post under his real name of Maynard A. Philbrook. He lives in Willimantic, CT. This information is available on line, in the public record. I wonder if he really has a job, and if so, what his employer would have to say about the way he acts on line? he has bragged about all the non compliant wiring and that they are grandfathered by the EPA to use banned chemicals. The place sounds like something the fire department, EPA, and IRS should investigate, along with the GAO, since he claims they do work for the federal government.

I posted the relevant reference in the NEC, and information from Leviton about their GFCI products. He ignored it, just like I expected.

Just call him "Junior", as in the JAW.
