Ever done a real life GFCI test?

I always wanted to find out if the GFCI really worked but never got around to actually sticking my fingers in there to find out.


I was sitting on a concrete slab with a demo hammer between my legs and shorts on. The cord was frayed a bit by the handle (yeah yeah...I know) and touched my inner thigh. I felt a very slight sting....and it tripped the GFCI.
 
I thought I got stung by a bee one time on a cord. But when I went to use it there was no power. The GFCI had tripped on the breaker an on the plug.

Yes I did check the cord at the beginning on the day like I did every day. With my new work I check all my cords between each job. All cords are checked before I put away a tool and at the beginning of the day.

On thing I do keep thinking about is putting a GFCI outlet on my tool box and using a cord to go to an outlet. A lot of the outlets aren?t GFCI though the buildings. I like the thought of having GFCI on the tool box because of stuff like my shop lights don?t have it. A spend a lot of time inside of a machine working on them.

Get yourself one of these. Cd & radi---You can have music and it has 2 duplex GFI recep., a charger for bosch batteries and a dc supply for your cell phone. The new ones are Ipod ready.

As much as I like a radio (By the way that Bosch has great bass :) ) you may want to get one of these...

...for your tool box for those places that do not allow radios. :)
 
Yes that’s what I need. Just need to mount it to my tool box.

I can see it now getting the cord run over by a fork lift.


now to get my boss to buy me one… and then replace it when it gets trashed.

My take on 527.6, is that you should have GFCI protection anytime you are using your plug in tools.

No I don't really enforce it except in commercial remodels, but that's only because I don't really inspect that much residential any more.

my take on 527.6 is that is does not exist in my code book.

Then you should get the same code book that I'm using. Makes it easier for you to agree with me that way.

In your code book it would be 590.6

Our small high current test sets (0-2000 amps depending upon the impedance of the equipment under test) trips GFCI's. We either have to bypass the GFCI's or use our inverters.

Yo quiero!

It's a shame I don't need any more cordless tools. Anyone know if Bosch batteries have the same mating gadgetry as anyone else?

I have an adjustable gfci tester. It has settings of 3, 4,5,and 6 milliamps fault current. It allows me to spin thru the cycle and test where a given gfci protected receptacle will trip at. Almost all are right on 5, I have had some 4s go off, and I returned the sixes to the wholesaler. I have not calibrated it since I bought it many moons back, but the repeated 5 milliamp trips tend to make me think it is working right.

Milwaukee has this made by Rockford Fosgate. No CD player, but it has an input jack to accomodate the apprentice's iPods.

This has a CD player, a Input for Ipod, and a 12v output for charging the Ipod while listening... and great bass...:grin:

Oh yea well... this also has the 12v output, and since there's no Mp3 version, and CDs are going the way of 8-track tapes, I figured this was more than adequate. Don't find other trades plugged into my spider box, it's bass is OSHA compliant, and everyone has batteries for it.

I actually accidentally touched a live wire in a switch box saturday and tripped the gfci it was on (they were outdoor lights). Got a tingle from it but not much.

GFCI test

GFCI test

This will show my age, but perhaps some other "old timers" remember it. I don't recall which manufacturer, I believe it was Cutler-Hammer, supplied their
distributors with a demo board when GFCI's first came out. It had a GFCI on a plexiglass board, and a "paper clip" (with retaining chain--like a bank pen--so customers could test and see how well the GFCI worked.
That was long before we worried much about such things a pace makers, lawsuits, etc.
The "try this" boards didn't stay around long..not sure if the manufacturer had anything to do with their disappearance or not.
