GFCI and a junction box
I have a quick question. Hard to explain, but I'll give it a shot. Imagine you have two rooms, each with outlets in it as per usual. In room 1, you have a GFCI and from it's load side you run the rest of the outlets in the room. From the GFCI line, you go into a junction box, which joins that room with room 2's outlets.
The GFCI should still protect the outlets in room 1 right? And joining other outlets from room 2 at the junction box off the GFCI's line, should be fine right? Basically, anything after the GFCI (load) will be protected, but anything on the line side will not, and should not effect the load side right? Just want to make sure. And theoretically, you could put one only GFCI outside the junction box, run your circuit to the line, and from load go into the junction box, and therefore protect both rooms, correct? |

A better way to describe it would be like this, you've got your circuit connected to the GFCI line, and from there you go from the load on the GFCI to the junction box. And from there you wire which ever rooms or outlets to the junction box. Basically I mean, can you protect two rooms with one gfci by connecting the two rooms to the junction box, which comes from the load side of the gfci. I'm having trouble expressing this in words :)

Yep.
Alternatively, You could use a GFCI breaker in the fuse box. There is no real difference. The primary function of a GFCI is to measure the difference of currents lowing in L1 and N. This subtraction is done directly by a transformer. It doesn't matter if the outlets are series connected after the GFCI or a combination of series and parallel after the GFCI. They will all be protected. |

I was just curious, because I have a room in the basement that I want to protect with a gfci, but I have a couple of other outlets in a different room that goes to the junction box. But they don't really need to be protected. But then I thought, why not protect them all since I'm at it anyway? And since I've got fuses, the gfci outlet is probably my only option right now. At least until I start the upgrade. Thanks again!

Again, thanks to everyone for all their valuable information as I wire up my Recording Studio addition. :) You guys are great! ;) I have another question reference the use of Junction boxes. On a couple of my framed walls, where I wired in outlets, some of the outlets (for like Exit Signs) are...
The house I bought has an GFI outlet in the middle of the back yard (they had a pool). I want to remove that outlet and place it further at the back of the property. Is there a issue with splicing the old wires to new ones w/wire nuts, putting them in a small junction box & burring it?
Can I connect a "constant" power source to a "switch controlled" power source in the same junction box? I am putting power to the deck at the rear of my house. One line ( "switch controlled " ) is for the lights, and the " constant power ", is for a GFI, as I don't want to have the GFI tied...
Is it OK to take a single 15A line off a 20A branch circuit. Specifically, I have a new 20A kitchen wall circuit which will exist only of two 20A counter GFCI outlets. I have had to rework that wall for the gas stove and want to run a 15A outlet for the gas stove electrics. Can I just take a 15A...
Hello. I have a quick junction box question. Is there a limitation to the amount of wires I can safely join in a junction box? If so, what is it and are there regulations to what size box I can use? Thank you. I would like the have 8 wires (neglecting ground) in one junction box (1 in / 3 out)....
