except you have an equal chance of tripping either the near one or the far one. And a good chance of tripping both... You won't be saving any walking. And like i said, you shouldn't be tripping them that often, if you do, then you need to fix the problem and not depend on the safety device.

I have found working in the field that when using the corded GFCIs plugged into a GCI circuit that I got nusance triping of the GFCI circuit. I can't tell you why unless it is the added capacitor affect of the extension cords, If a boost transformers at the end of the run is used it trips them quite often.
I wouldn't add one if it was me but that is only opinion.Art

The addition on my house has two GFCI in series. One is in the laundry room with the washer plugged into it. After it, 2 interior outlets and then an exterior GFCI outlet. The exterior I believe is the end of the series. If it isn't then there is only one additional interior outlet that may be on down the line.
I went several rounds with the contractor and electrician over this setup, but since I rent the house and don't own it (in-laws own it), I couldn't really put my foot down. On the exterior outlet, I told them I wanted it in a waterproofed exterior box. "It's under the carport where water will never get to it. You don't need the box because its GFCI."
Wrong. Had some water on the slab splash up on it (slab slopes down towards the house!!!!). The water tripped the outlet, plus the one inside. A little while later, I tried to reset the exterior outlet and smelled burning plastic. The upstream GFCI tripped again, thankfully.
So, $40 later and a trip to Lowe's, I now have a new GFCI outlet INSIDE a color matched waterproofed box for the carport. Now to get FIL to caulk around it to make sure it is watertight. He's better at caulking than I am.
Long story short, you can put GFCI in series, and in my situation it is a very good thing that I am set up that way. In my shop, when I add the GFCI's, I'm going to put them first in series as close to the breaker panel as possible.
Also, since I get water in my shop so frequently, I trip all the breakers in the shop panel when I lock up for the day."It's a dog eat dog world out there, and I'm wearing Milk-Bone underwear."- Norm (from Cheers)

GFIs in series
Most of the inspectors Ive delt with will fail a job with 2 or more GFIs in a series.It creats more problems than it helps,also looks like you dont know what you are doing.The bitterness of poor quality lingers long after the sweetness of low cost is forgotten!Comment

GFCI is required by code for garages in California. Remember that one GFCI when properly wired will protect downstream outlets as well. Most GFCI outlets have a line and a load connection that can be used to protect other outlets.RAGS

Generally anyplace where you may be standing on a grounded surface, or have any part of your body touching a grounded surface even though the path is through water or dampness, you should have a GFI. I am an electrical engineer, not an electrician, and I don't have access to the latest NEC (as modified by local code), so take that into account. GFI's work by sensing the difference between the hot wire and neutral wire current, and if different, assumes that you are carrying the difference through your body and trips before you have enough current through you to do harm.
I grew up in the days of knob and tube wiring. These niceties were not required or available then.
If you want to make sure it's right, use a licensed electrician.

With the idiots I was dealing with, I'd believe it. However, given that both plug location are where I could be standing in water, I like the idea of the GFCI close by."It's a dog eat dog world out there, and I'm wearing Milk-Bone underwear."- Norm (from Cheers)

If it weren't for the cardboard box they came in saying 15 they were exactly alike.
If I had had the time I woulda returned the 20's for 15's and saved like 3 or 4 bucks a piece.Comment

Here's an interesting one- bought a handful of P&S GFCI's a few weeks ago. Mostly 15a but a few 20a. Get home and as I'm installing them I notice that the faces on the 15 are the same as the 20 (that extra slot thing) and that the UL sticker says 20, and that the model number molded into the plastic is the same on the 15 and 20.

and that the face was exactly the same as the ones in the 20-A labelled package which to me means the slot pattern is identical.
Probably marketing finds that tehey can charge a few bucks ($3?) for the 20A, and industrial customers placing large orders will order to specification.
Then manufacturing said, if we make all one style intsead of two styles, we can make them for mcuh cheaper (large volume pricing) so they just decided to lose a couple of profit bucks to those who figured it out and pack the same items in both packages.Last edited by LCHIEN; 10-08-2009, 05:59 PM.Loring in Katy, TX USA
