According to the 1999 Code book, replacing a two prong recepticle with a GFCI recepticle is acceptable if labled GFI protected with no equipment ground. Is this code still acceptable or has it been updated?

It is still acceptable.

Ken, when you post you need to specify 1902, 1905, 1908, or 2002, 2005 ect.

Thanks.

Well, there was no 1902 or 1908.

Or more to your point, are we talking AD or BCE? :D

You can be #1 if you want just fill out the 10 pages forms and submit to the chief mod and ask him to change the order. I give you my spot. :wink:
 
when replacing the two wire receps with gfi's can you load out to other receps changed to grounded type if the e.g. is the conduit? Or do you have to change each recep with it's own gfi?

Yes you can but they must be marked as having no equipment ground. The labels are in the GFCI recep. boxes.

I think this is a bad fix myself esp. since the labels won't go on in most cases and will often fall off. The fact that the tester doesn't trip is not an issue since the only approved method for testing a GFCI is the button on the receptacle or breaker.

How stuff works said:
A GFCI monitors the amount of current flowing from hot to neutral. If there is any imbalance, it trips the circuit. It is able to sense a mismatch as small as 4 or 5 milliamps, and it can react as quickly as one-thirtieth of a second.

The labels are usually taken off by the HOs before you get to the bank with their check anyway.

You can indeed use the feed-through terminals, but there is a catch: You are not supposed to inter-connect EGC's on GFCI-protected unbonded grounding receptacles, so the existence of the conduit would render this exception non-compliant for your use.

The GFCI will not trip with a plug-in tester, because it does not have access to any grounded condcutor ahead of the current sensor. However, the built-in tester functions fine.

That a plug-in tester does not work is of no consequence, and is not required to work.

Like the others have said it is legal. But I suggest taking a look at 250.114 for a list of equipment that we are not allowed to supply from an ungrounded receptacle.

Basically any appliance that has a three wire cord would create an NEC violation if plugged into the ungrounded GFCI.

Of course homeowners will plug those things in, they really will not have read 250.114.

It might be a better if you simply provide a circuit with a grounding means. Good luck either way. :smile:

If the job is steel conduit or tubing there is an EGC, there would be no requirement to use GFCIs for receptacle replacement.

Good call, Bob. You've earned your points for today.
 
Here is a little diagram that may help but as Bob suggested if that metal conduit is grounded back at the service then there is no need for a GFCI recep. Just replace the 2 wire receptacle with a 3 wire and connect the ground to the box. I find the last diagram quite amusing as I cannot imagine a situation like that. Enlighten me please...
