Unknown Wire

We had to cut into our drywall because of a leak in our shower and found this random wire hanging in the wall. It’s somewhat near an outlet, but the wires going to that outlet are all enclosed in another casing. We have no idea what this is - any suggestions/ideas on what it might be?

How to fix this junction box

So I'm smart enough to know how to not get myself hurt, but I always seem to get tied up on the little things. I have junction box. It has 3 sets of wires going through it. 3 black, 3 white, and 3 ground. None of them are connected to anything. The reason is because there used to be a light that went there, but it was removed, which coincided with our house intermittently losing a whole phase, and just a lot of things happened.

We have since gotten everything else fixed, but the one who pulled down the light (I moved in in the middle of all this) doesnt know where that light is, we don't really have the money to buy another one, and we re missing a bunch of power and such from a number of outlets in the room this lilght was in.

I want to just join the wires together to complete the circuit. Do I put all the whites together, all the blacks together, and all the grounds together, or do I figure out the pairs and go from there?

Relocating Wall Outlet

Hey everyone, I have one of those dumb TV nooks above a gas fireplace. I want to close it off, but since the wall outlet is in there, I need to relocate it to the front when I close this off due to code.

I'm curious what the best way to essentially extend the wire out to the new outlet would be. Would I just get a length of romex and wire nut / crimp to the ends of the existing run going to that old outlet?

Thanks!

Electrical/mounting components for ceramic wall sconce

Hi Electricians of Reddit!

I’m in the process of building a house and would love to create some custom ceramic wall lights/sconces that our electrician will install. To make sure I design the ceramic parts correctly, I’d like to buy the necessary electrical and mounting components in advance, so everything fits together seamlessly.

This is outside my usual area of expertise, so I’m not entirely sure what I should be searching for online to find the right components. I’m envisioning both vertical and circular sconces, similar to the example images attached. I’ve also found an installation guide for a similar vertical sconce, which includes a diagram of its components.

Are there specific terms or names I should be using to find compatible mounts/brackets? And does anyone have advice on mounting these securely to the wall?

Thanks in advance!

Feeder wire to detached garage sub panel

I’ve tried doing some research on this. It seems opinions are mixed and I can’t get a straight answer. I’m in Ohio and would like to only pull/buy this wire 1 time. It will be entering the house and be in ground.

What type of wire should I be running for 100A service to a sub panel with? It will be going from the main panel (200A) into the crawl space, out into a trench and then in the side of the garage to sub panel.

Prefer aluminum do to cost. It’s a 75ft run. Any help would be greatly appreciated!

Can I run UF wire outside in flexible conduit?

I want to add a second motion detector floodlight - about 10ft from the first floodlight, and about 12ft off the ground.

I will run 14/2 UF wire outside from the old box to a new box.

  • For cosmetic reasons, can I run the wire in flex conduit?

  • I saw 53% capacity for NM in conduit? Does this also apply to UF? Are there other restrictions for UF in conduit?

I’m probably over thinking this.

Thanks

Looking for recommendations for outdoor, battery operated string lights!

I am part of a community group that decorates our local area for Christmas and other festivals. Last year we wasted a lot of money on what turned out to be terrible quality batter operated outdoor string lights for little string tress along the roadside. They all stopped working within a few days. Water got into the battery box despite us cover them in plastic bags and tapping them shut, others just died from the cold (Ireland in December). I am hoping someone here might have a suggestion that would help us out, thanks!

Vents heat recovery ventilator beeps, turns off

I bought an older house and it had one of these installed (I don't know if it's the same just looks the same) it had a remote but not anymore (would be nice to find the IR codes for it tho).

It used to work, but one day when I used the switches on the side it ran for a few seconds, started beeping, the fan turned off, and then continued beeping until it was turned off (checked it on my workbench and it did the same).

So now I don't know what to do. It is quite an expensive device and it seemed to work fine, with no water damage or loose cables on the inside.

Feel free to ask for any more specific information (the only thing I couldn't find were model numbers).

Any recessed 20 amp GFCI receptacles?

We’re redoing our kitchen backsplash and while we’re at it, we would like to recess the receptacles behind the microwave and air fryer. That way there isn’t a huge app behind them due to the plug sticking out of the receptacle.

We don’t want to move the receptacles beside the appliances because we’d rather not see the plugs and we also already have plenty of accessible outlets on the wall.

The wall is 2x4 construction so I don’t have a lot of extra depth to work with.

Do I have any good options here?

Is it legal to have the internet equipment and smart home panel in the electrical closet/room ? What about a server and UPS ? Would that count as using the room for "storage"?

DIY mistakes

Hello all, going at it alone while replacing some rodent chewed wire. The rodents chewed through two wires which were part of a lights and switches circuit.

I was under the assumption that the wire would lead to more than just lights and switches, so, I used 12 guage wire, thinking I would possibly upgrade the circuit to a 20 Amp at a later time (thinking outlets would be on the circuit as well, once again I'm not an electrician)

Well I've now found out usually 14 guage is used for switches and lighting. I haven't connected anything yet, just ran the wire with a fish tape to the boxes. Is it against code or some sort of violation to use 12 guage wire on lighting and switches? The rest of the circuit is 14 guage old cloth wrapped wire with no ground. Thanks!

A brother (or sister) wishes he (or she) Could.

What are the most frustrating paper-work or communication related parts of being an electrician? I want to understand the most common tasks associated with the electrical industry outside of doing physical electrical work :)

Dimmable lamp to none dimmable lamp conversion

Hi, absolute amateur here, I have a floor lamp that has a dimmer slider switch on the power cord, the other day it stopped working after 10 years, I think the dimmer is the problem.

We never use the dimmer and I wanted to know if I could simply cut the dimmer out and wire a standard on/off into it instead?

The lamp matched all the light fittings in the room and is discontinued now, hence the need to fix it.

This is UK electrics and the lamp takes G4 bulbs if that makes any difference. Ask if you need more info?

Thanks

Our home is from 1947- is the wiring running horizontal or vertical through the wall? Asking due to concerns about drilling

As the title states- though I'm also wondering if there's any way to tell apart from going into the wall ourselves and looking.

I'm just trying to figure out if the wires are running up through the walls or across, as we're drilling for shelves

I have a general technical question about how the main breaker in electrical panel is wired

I understand the basic workings of a single pole 120v breaker in the electrical panel. if too much current flows from the 120 supply side (either L1 or L2) to your branch circuit, the breaker trips.

but how does that big 100A main breaker at the top work? dont the L1 and L2 feeds from the pole flow thru that main breaker and then L1 goes down one bus bar and L2 goes down the other? so dont you really need 2 main breakers, one for L1 supply to bus bar 1 and other for L2 supply to bus bar 2?

the diagrams i see online seem to show a breaker with L1 supply on one side and L2 supply on the other side..but that would basically be a short circuit right?

Should I call someone?

Currently 1:15 am and I was attempting to install a bar above a window to hang plants (Great timing)

As I was drilling the holes I saw a bright flash and immediately stopped. I'm fairly certain it was the lamp behind me that got super bright. It was only for a second and I never heard a pop or tripped a breaker and I don't smell anything strange.

I'm wondering how serious this is and if I need to get someone here. With it being so late at night, it'll have to wait at least till morning and I'm a little scared to fall asleep if it can start a fire later.

Any and all advice is appreciated, thanks in advance!
