Is that existing box on a light switch or dimmer? Back in the 80s, they loved their switched lamps. There's no issue extending a circuit from an existing box. You could probably just hook up the new NM to the spare set of screws in that box. TR outlets are a nice upgrade, plus your new box would need one as well. GFCI is overkill though. Ground wires were standard by the 80s, so you shouldn't need GFCIs to do the 3-prong upgrades. Perhaps you're confusing that with AFCI upgrades? Because those are different. Still, that would be easier to accomplish by swapping out for AFCI breakers.

wolrah posted:In the better part of 20 years of IT work the only times I've ever seen actual interference problems caused by ethernet cables being run too close to power they were either draped directly over a fluorescent light fixture or we're talking about industrial levels of power. Mostly workshops with big motors, one time a massive arc furnace where the power wires literally jumped when it was turned on. Even those interfering was due to the older magnetic ballasts having, well, big magnets in them. Newer electronic ballasts aren't anywhere near as bad as the old ones. Also, they do make cat5 and 6 rated for direct burial. kid sinister fucked around with this message at 19:47 on Mar 17, 2023 |

Super-NintendoUser posted:I built a decent sized pergola on my patio, and I'm looking to get power to it. In the past, I had some twinkle lights and a fan, and I just ran an extension cord from an outside outlet to it. I'd like to do a little better. I'm thinking this: Extension cords aren't allowed for permanent use. There's only one exception for this, and it's intended for indoor wall-mounted TVs. If you're going to the trouble of conduit, why not just wire it up permanently? If you already had an outdoor outlet on your house, they make Weather Resistant extension boxes. You could take out your existing outlet, put on one of those boxes, put the outlet back into it and you'd have a starting point for conduit out the side or bottom of that box.

First thing I did when I moved into my house was to label the panel correctly. Made it easier to split a circuit in half when my PC and TV would trip the breaker if they were both on at the same time.

TooMuchAbstraction posted:I need to splice together some ground wires for a low-voltage device (a game controller; I'm wiring up the buttons). We do have an electronics thread here in DIY. I'm on mobile otherwise I'd link it. We love helping newbies! That being said, since this is a ground wire that won't be exposed, you could just run a bare wire and solder to it where needed. You can make any wire bare with a razor blade. You don't even have to make the entire wire bare, just cut back spots to solder to along the length. Most electronics grade solder now is rosin core, so it has the flux inside it already. Just use an electronics grade solder. You can't use the stuff from plumbing. kid sinister fucked around with this message at 00:42 on Jun 25, 2023 |

obi_ant posted:I rent a really old apartment that was built in the 1930s. Some of the outlets are able to accept three prongs, but when I opened them up, there isn't a ground. I opened a few other ones and it's a mix of metal and plastic electrical boxes. Here is a picture of the metal electrical box. Cloth wire never came with a ground wire. Well... ground wire first appeared in the 1950s inside NM wire that had an outer sheath that was woven, but the inner conductors had plastic insulation. 1. Yes, all but the oldest surge protectors will offer some neutral protection. 2. This is only allowed if the box itself was grounded. You'll need an old fashioned 2 probe circuit tester to see if the box is even hooked up to anything. GFCI outlets are most likely what the LANDLORD would have to do. Don't do anything if you're just renting.

Motronic is right. If that has cloth wire insulation, then it predates the 1950s.

Also, keep in mind that only dates when it was made, not necessarily when it was installed. Someone could have spotted it at a flea market when it wasn't so old 20 or so years later, fell in love with it and installed it. If you're wondering, reproduction cloth covered plastic insulated wire is available today. Plugs too. I've used them before when restoring a radio from 1940.

That isn't to code. It will need to be replaced. Did they do that to fit the depth of the wall cavity? There are other choices for old work boxes. You have more choices for depth with steel boxes with plaster ears and those bendy side brackets.

gonadic io posted:(x-posted from the general DIY thread) In the US, we call the frame of the outlet itself the "yoke". They're grounded, which means the face plate screws are grounded. Do you have a 2 prong circuit tester? See if there's a circuit between the hot hole and the faceplate screw. If so, just screw that spade terminal to the faceplate screw. edit: another option would be to buy a repair outlet and just run that green wire to the ground prong. kid sinister fucked around with this message at 22:18 on Oct 18, 2023 |

Epitope posted:My garage has two man-doors. The light switch is by one door. I want another switch by the other door. Does it work to run the wire on top of the drywall, in conduit or whatever? The existing switch is in a behind-the-drywall box. Can I mount the surface box over that box, or is there a box extention or something? Will this be hard, should I just call an electrician? That wireless solution would be quick, but to answer your question, yes, there are surface mount extension boxes that you mount on existing in wall boxes that allow for a starting point for conduit. Your two hard wired options would be plain old conduit or wire molding.

Steve French posted:Is there any way to tell from the breaker itself (or does it depend on the model) if it’s tripping due to a ground fault or an overload? Take the breaker cover off. Undo that circuit's neutral and ground wires. Use a multimeter continuity test and see if there's continuity between that circuit's ground and neutral. Now those wires are only supposed to be joined in the main breaker panel. If they have continuity, then those wires are touching in the wall somewhere and you have an arc fault. Now try for a circuit between hot and ground. Those 2 touching would trip a regular breaker. If after those 2 tests you got nothing, it's probably an overloaded circuit. Note that these tests can't tell you where the trip is occurring, only that it has occurred. Finding where is a bunch of legwork.

If you do have to put a fridge on a GFCI outlet, they do make GFCIs with alarms so you at least have a chance at saving your food. I recommend them for deep freezers too.

Rat Poisson posted:In my 1960’s house I have an outlet in the kitchen where it looks like someone strung a bare ground wire from one more-recent circuit (80’s?) through a couple stud bays to another outlet that only has the original 1960’s 12/2 (with no ground) NM cable in it. The outlets are on separate breakers. So the PO seems to have effectively provided a ground to the original 60’s outlet using this jumper wire from the newer circuit. The newer 80’s outlet uses what I’d call “modern” NM 12/2 w/ ground wire as far as I can trace it from the kitchen though the attic and back to where it enters the wall for the final run to the main panel, so it looks like that part of the 80’s wiring is done correctly. Believe it or not, that's actually a code legal 3 prong upgrade method. You can run bare or green jacketed grounds to ungrounded outlets to upgrade them to 3 prong ones. Note: it has to be of appropriate size for that circuit: 14# for 15 amp circuits and 12# for 20 amp circuits.
