gfci breaker in lieu of gfci receptacles?
Comments (11)Remember a GFCI does not trip due to an excess of current, it trips when it detects current (what's a standard one here, around 50ma?) going to ground, so it doesn't carry a 'load' per se. I also like the receptacles because you see and KNOW that circuit's protected, when I first bought my house and saw a regular receptacle in the main bathroom, I assumed it was unprotected (former owners had done so many dumb things already) and bought a protected outlet...now I'm trying to decide where I'll put it, probably in my kitchen where I have outlets near the sink that don't comply with the current BC electrical code - I've assumed it's a 'grandfather clause' but I'd still prefer the protection....See Moreretro fitting non grounded receptacles
Comments (4)You can obtain nearly the same level of protection by using GFCI receptacles. This is a code approved way to put 3-hole receptacles on a circuit without a grounding conductor. Every GFCI receptacle comes with the required stickers. The 'No equipment ground sticker' goes on the GFCI receptacle, while any downstream (load side of the GFCI) 3-hole duplex receptacles get the 'GFCI protected' AND a 'No equipment ground' stickers....See MoreGFCI Receptacle Trips When 3-Way Light Switches Are Turned On
Comments (6)I'll be investigating all of these options today. The one that sounds like a definite possibility is the third option where the neutral for the lights is connected before my GFCI receptacle. After finding out that the GFCI was tripping when I'd turn the sconces on, I took the fuse out for that circuit. (I have a Federal Pacific Fuse Panel, by the way) I had to leave, and left the fuse out overnight. I went back the next day and realized that the front hallway light and the outside lights beside the front door weren't working. They are on the same circuit as the living room. But, when I put the fuse back in, they weren't affected by my tripping of the GFI. So, while I thought the living room outlet where I installed the GFI was the first device on the circuit, it's actually the front hall light or exterior lights. Perhaps the sconces are getting neutral from the front hall light? I did notice that inside the box for the first sconce, I had a set of wires coming DOWN inside the box... This was odd to me because I have no overhead light in the living room. For a little bit of reference, I uploaded the floor plans I made of the house. The fuse box is in the basement, located in the SW corner in the plans. The circuit we are talking about covers the Front Entry Lighting, Living Room Receptacles, Living Room Sconces, Dining Room Outlet, and Dining Room Overhead Light.

Comments (4)You must use wet rated conductors here. THHN is not wet rated. Fortunately most stuff sold as THHN is also rated THWN (which is wet rated). You can not use 20A receptacles on a circuit protected by a 25A breaker. Use a 20A. Why are we using #8 here? Are the lengths such that we are concerned about voltage drop? If you are determined to use GFCI receptacles and you're going to use conduit, there is no need for a GFCI breaker. If you want both circuits to show up in each set of receptacles, then you can just wire it up as a MWBC. As you probably know (based on the choices you offered), once you are on a protected side of a GFCI, you many not share the current carrying wires (hot and neutral) with any other circuit. Make sure you use in-use style covers on these boxes. They make double ones....See Morecobraguy
