Hi all
am looking for a hopefully easy to obtain, not too expensive method of demonstrating that a receptacle is GFCI protected... long story short. Am selling house, got offer. Home inspector came through and wrote up two receptacles as being "ungrounded" despite them actually having the blue stickers on them that said "GFCI Protected - No Equipment Ground" (duh) before you ask, it would be fairly difficult to pull grounds to these boxes, otherwise I'd not be fighting. Also there are a approximately 5 or 6 other receps throughout the house that I haven't grounded yet that are in a similar situation, and I don't want to open that can of worms whereby accepting that the lack of a ground at these receps is a fault that needs to be corrected leads to the request to ground *everything.* (house was built in 1948, before you ask. I did update a good bit of the wiring already, just not all of it. Everything is to the best of my knowledge code compliant at this time, and in fact I got a permit for the rewiring I did on the 2nd floor a while back.)
SO.
I scanned the page of the NEC (2008 edition, which is what my AHJ is using these days) addressing the replacement of ungrounded receptacles; called the head inspector to confirm that there were no local addendums to the code (he said no) and so I have a case, right? I just need to demonstrate that the receps are in fact downstream of a GFCI.
Here's where I had a moment of dumbass. I figured I would just stop by the Local Hardware Sellin' Emporium and get one of those plug in cube testers - kind of like the one I already have but this time the fancy one with the little button on the top to test a GFCI. That should do it, right? Well I get it home (not the house for sale, my current temporary residence) and plug it in to a kitchen recep, push the button, GFCI pops. Then I read the instructions - says it may not work on ungrounded receps. Of course it wouldn't - it probably just has a resistor that the button inserts between hot and ground so that it allows a current slightly higher than 5 mA @ 120V. duh!
So the question is - is there a tester available that I could use to demonstrate the principle to someone who's not really clueful about such things that the GFCI really works? I could use a test lead to connect the ground pin to a faucet or something, but I have a feeling that that wouldn't really help the case that I know what I'm talking about and did a proper job in front of people who aren't really clueful about electricity and have never heard of the NEC...
any ideas?
thanks
