You remind me of me... If I'm thinking of something, I've got to try it!

And you're correct with everything you are saying!

GFCI troubleshooting


You caught me red-handed Billy-Bob! I am guilty as charged !!!

I am not sure what I did wrong during registration to this forum but my message that appears "today on 04:48 am" was actually posted on Central US Time at 11:48 pm on Saturday night.

And yes, indeed I was in bed 15 minutes later.

But guess what, by 00:15 AM I was up again and in my pajamas I went back at it!!!

Actually, I was lucky I had a spool with about 50 ft. of 12 gauge wire and run it from the garage receptacle to an outlet in the house and stuck it into the ground hole. Then did my testing again with the aforementioned results. It all happened in about 10 minutes. I was actually disappointed this was so easy and did not think of it earlier. As you can see my next post, the one declaring victory over the GFCI mystery, was posted at 05:41 which in reality was 00:41 on Sunday "morning".

I was back in bed by 01:00 am and my wife was so happy that she did not complain to me for -momentarily- preferring the company of wires and GFCIs to her (lol)

Today, I run the green wire and everything is good and safe!

Thank you for your feedback and schematics (wow, what book/website is that) and thank you all for helping as well.

You all have a great day now!

GFCI troubleshooting


So far as the correct time. Click on "User CP" above, then under Settings & Options, click on Edit Options. Then about 3/4 the way down that page you can set your time zone.

So far the schematics, just go to google.com, click on "Images" at the top, then search for something like GFCI or GFCI schematic.

The parallel wiring is more difficult to find because you first need to know what the word "parallel" means as applied to wiring. But I searched google.com images for GFCI parallel to find that.

I don't know what you want to be "when you grow up", but you are exceptionally bright and learn very quickly...

If you are interested in electrical wiring or other home projects, the following bookstore has a TON of books on all subjects ranging from beginner to far advanced above your typical worker in the particular trade...
http://www.buildersbook.com

Then if you are interested in electronics and programming, there is a kit to learn about microcontrollers sold at Radio Shack called "What's a Microcontroller BASIC Stamp Kit". Microcontrollers are the "computer chips" which just about every appliance uses these days for control. That is here and link to free book 2nd link...
http://www.radioshack.com/product/in...ductId=2117994

Free book...
http://www.parallax.com/Portals/0/Do...3-WAM-v3.0.pdf

The you can search google.com for the words...
basic electricity
basic electronics
home wiring
basic wiring
Etc.

All sorts of stuff out there!

For exceptionally bright people, there is an organization called "Mensa". That is here...

GFCI troubleshooting


Τhanks Billy_Bob, I am flattered but I am only another regular person with an average IQ. I also think that at the age of -almost- 50, I am as normal as one can be in this crazy world.

I am an IT Manager so I am comfortable around schematics, electricity and computer gadgets, etc, that refuse -occasionally- to cooperate. I am also an amateur musician, I play the guitar, bass, some piano etc but -on my spare time- I am also into building solid state or simple tube amplifiers.

Actually, I do not feel very proud about my troubleshooting skills yesterday, I should have suspected the inadequate grounding from the get-go, but I was thrown-off by the Sperry tester. Actually, I will contact them for sure on Monday, it is a real hazard if they sell a tester that says your ground is OK but as far as a GFCI goes it is n't. I mean using this outlet with a wet tool could have killed me, right?

My wife and I inherited this old (built in the late '40s) house from a relative so we are trying to fix it and rent or sell it. It is not very inhabitable but we do stay there over the weekends while we are working on it. Actually, I like home remodelling very much and I can do a lot by myself, only I am a perfectionist and it takes me too long to be efficient. But there is not much electrical work this house needs, apparently it was rewired and upgraded recently, I mean it has conduit all over, very little flexible armored cable and no romex at all. The wires look in decent shape and the board is a 100A so we are OK by code for this area. All I did is replace some broken covers and some older outlets plus installed GFCIs where code mandates it. I was able to pull a green (G) cable from the house to the garage but only after I used one of the existing two wires to pull it through. Actually, I used the white (N) to pull 3 wires, a green (G), a white (N) and another black (H) in case I want to run a second line or even install 220V in the garage.

But staying up 'till 1AM to figure out a GFCI grounding problem is not exactly what I would call exceptionally bright, but -again- I thank you for your kind words, your help and the very interesting link (mensa.org) you supplied me.

I am sure we will talk again soon.

Thank you (an all others) so very much !!!

BTW, if you have a GFCI where fused relay contacts are the only problem you can use it as a ground fault detector that will give you a numerical readout, without paying Fluke many bucks for their special meter.
To do this you first need to post the numbers off of the IC that is inside this thing.
