Hey /diy/kes, I'm trudging along replacing a lot of shitty crumbling K+T in my house, encountered something a bit tricky (for me). Previously, there was one feed running up to this junction, solder-jointed together and splitting one line into the 1st room (duplex outlet-->single pole switch-->light/fan. The other joint ran to the ~~closet in a different room~~ and is just a light fixture with a pull string. Would wiring like picrel be insane? Seems like it's essentially the same thing as the previous solder-joint setup. Welcoming all the due criticism and will post some of the nasty K+T pieces tomorrow for your viewing pleasure.
>>2874959What's the purpose of the green wire? Isn't the black wire already ground? Why does it need 2 grounds?
>>2874962for safety
>>2874962>Isn't the black wire already ground?It is, until it's not.It's a dedicated path in case of a fuckup. It's not needed if there is no fuckup, until fuckup happens. Also GFCI
>>2874959Do you want the right light to be turned on constantly?
>>2874962>Isn't the black wire already ground?The green wire is a circuit protective conductor which allows a low impedance return to operate an overcurrent protective device in case of fault in a metal or class 1 accessory or fitting and a bypass path for operating a current imbalance prote tive device.The other wire is a neutral for normal condition current return.Under normal conditions both wires should have insignificant potential difference to local ground, which may be where the confusion arises.Also americans will call the negative terminal of a battery a ground despite it being a completely isolated system. They are obsessed with the word.
>>2875271>a light fixture with a pull string.LEARN. TO. READ.
>>2875205OP here, thank you. So, I installed a standard 20A duplex outlet due to the size of the cavity and what space was available in said cavity. Really old house with about 3 inches(being generous) in between walls. I was able to just barely fit an old work single-outlet box in, but it was a squeeze.All lines will have a dedicated ground to the main electrical panel, would the GFCI in this case just be an additional safety function?I had considered putting one of those 1 inch on-wall outlet boxes, but the box fixtures wouldn't have anywhere to mount to. If the GFCI is absolutely necessary, I'll have to get creative and rig something up in the wall cavity for the on-wall box to mount to.

Unnecessarily complicated, unless you don't have walls open or attic access for a complete rewire. I suppose it will work, but I would do it differently.T. Sparky
I'm am here for the knob and tube.
I would use wagos instead of those dodgy wire nuts
>>2874959Why the 12/3 after the switch box? Is there a wire for something that’s not in the pic? Also it looks ok but I’m retarded and this is 4chan so…
>>2875434I don't have walls open or attic access. Agreed it's complicated, and I would rather have run a straight line down to the junction box in the basement. >>2875423>>2875454This was a stock image that I tweaked for my own display purposes, since my issue was a bit more novel than most issues. It's standard Romex Hot/Neutral/Ground wire. >>2875440I did! and they worked a bit better for this, made it easier to keep my brain straight if nothing else>>2875439It's coming brother, check back this evening, I'll have an ugly junction box and the wires I pulled out.
>>2874959Does the other room closed have an unswitched phase already? Otherwise if you ever want an outlet or a switched light or whatever in that room you’ll have to change it up again>>2875272> Also americans will call the negative terminal of a battery a ground In automotive the vehicle frame is considered ‘ground’. Positive ground means plus is wired to frame, negative ground means minus is wired to frame which is obviously more common. Ground just means ‘reference point for voltages in the system’
>>2875534This is a great point, and I know I'll probably get a lot of hate for it, but in that closet I'm running raceway to the light. The outlet happened to be directly opposite the floor of the closet in the other room, so I poked a small enough hole through to run the romex in. I suppose if the next sucker wants to install a switch instead, they could easily cut the run where they need to and install a raceway switch box. >>oildowndrain.bmpPics as promised
>>2875550ugly ugly stacked(why?)junction boxes. Thursday I'll upload the interior pics, sure to be a laugh. Check out the solder joint.
>>2875552FUUUUUUUUUUu
>>2875553'nother solder joint and crumbled tube
how bad is it? i know, open ground, but the 36mA should be at most 30mA, as well, right?
>>2875846That's a nice little outlet tester, I just can't justify buying any more sparky peripherals. We only get 120V in the states but since mine isn't going to be open ground, I'm not very worried. Additionally, This circuit is only running 3 outlets and a fridge (old houses love to crowd a circuit), plus a few led bulbs, would be hard pressed to hit 20A with my usage. I do have an open breaker slot though, and if I'm feeling really confident I may split 2 of those outlets and the fridge to their own circuit. Will post more pics after the holiday.
>>2874959Put the outlet in a separate box near the floor. Put a switch on the second light, you can still use a pull string if you want. Your 12/3 is really 12/2. You do not need 12 gauge for the lighting. You need a ground to the switch.
>>2875938It cost me some 5€ €, i think, on AliExpress. Open ground is from a supposedly grounded socket, though, so all in all a good investment, which I can always sell later at a profit...Euro RCD should be 30mA btw.
I currently have a 4 gang switch on my wall that I want to build a bookcase over. I plan on cutting out a square in the back of the bookcase to allow access to the switches, but I only want to use 2 of them. One switch is for the ceiling fan light which I don't have and the other is a 2 way switch for the kitchen which never gets used.Am I able to just remove the 2 useless switches and cap the wires and leave them buried in the wall box behind my bookcase? Or do I need to completely remove these circuits to be up to code.
>>2876354Leave the switches you don't want to use. they are not hurting anything. Otherwise your wall box becomes an unwanted junction box. Buy a box extender to go through the shelf back. Put the switch plate onto that after finishing the shelf.
