Inspection went well. Just need to add grounding screws to some metal boxes, and some steel plate behind two of the plastic boxes.

The listed product for this type of thing is cat poo poo (duct sealant) but a silicone sealant that doesn't produce (butyl?) Acid when curing should be fine too.

I've been trying to get an electrician out to open up one of our walls (it's sheet rock) and install some new boxes and outlets lately. For some reason every time one of them hears "open the wall" they ghost me or act like it's never been done before. I don't get it...is this an uncommon request?

Normally you just fish wires in from above or below and use old work boxes, you shouldn’t need more than a couple small holes to get the wire where it needs to be. Open the wall implies major work and/or some idiot used expanding foam insulation that needs to be dug out to make it possible for a cable to be pulled.

Can anyone throw some suggestions at me for wire runs for my overhead lights? I’m a bit confused. Wanting two circuits - one with living room, dining room, office and one with bedroom, hallway, utility room. Kitchen and bath are separate and wired already. Living room, dining, and utility will have to be three way switches. I have attic access to all of them but the hallway - it’ll take some fishing to get to the fixture but I think I can get to the existing switch easily enough.

skylined! posted:Can anyone throw some suggestions at me for wire runs for my overhead lights? I’m a bit confused. It's possible to both drill down from the attic and drill up from the wall boxes. It takes a bit of measuring the walls and making a map in your head, but you can drill down through the top plate to the existing boxes. Drilling up from below requires the long bendy drill bit. Fishing cable into an existing box when the walls are closed is technically possible, but extremely difficult. It might be easier to remove the boxes from the walls. Drilling up from below requires removing the wall boxes. Now it is possible to remove the existing boxes out of the wall through their existing holes in the drywall/plaster. In normal home construction, boxes are fastened to the studs with 2 nails: one on top, one on bottom. What you'd want to do is stick a saw in the gap in the drywall between the box and stud and cut through those nails. A pocket hacksaw can work for this, but if you're doing several boxes, I'd recommend an oscillating tool. Release the cable clamps in the old box and maneuver it out of the wall. Once you got the old boxes out, an old work box can take their place. You may have to enlarge the hole in the drywall/plaster slightly. Protip: before you start, take the face plates off of the wall boxes. Stick a piece of painter's/masking tape beside the box. Mark the level of the box's top or bottom screw on the tape. You now have a reference for how high to mount the new box so it matches the old one while having a mark that's easy to remove when done.

Thanks for all this but I’m more stuck on the wire topology. Physical access isn’t a problem - my house is plaster and lathe with no fire breaks and I can mostly follow the old runs for pre drilled holes to run through. Wondering if this is a good use case for a star topology, running power to a junction and then branching off from there to switches or if there’s a better way to do it.

Stop overthinking it, just run power from box to box, if it makes it easier put a junction box above/below each switch.

Yeah the space I'm trying to wire has no attic and is built directly on the slab - so there's no space to fish from.

Normally I hate Twitter, but that's a good read. I worked as a telephone lineman in college and was amazed at how old poles, connectors, and hardware are. Demo'ing old lines was fun, you'd cut the 3/8" steel strand on one end and watch 20 telephone poles fall down like dominos. The only thing supporting some sections was the fact that they were still standing and anchored on either end.

Star topology doesn't really work with NM. You run into issues with box fill at the star centers. When it comes to NM, it's mostly shortest route daisy chaining, running /3 as necessary.

If you're coming up from the basement or down from the attic where you can fit accessible junction boxes and not doing any wall demo, trunk it and branch off for each individual outlet. You'll only ever have 6 current carrying conductors in a box at a time that way and you won't have to gently caress around with daisy chaining through existing walls, which loving sucks at the best of times.

So I know the code requirements for panel space inside but what is required outside around the meter and service panel? Same? We’re maybe looking at building a deck on the same wall our panel is on that would come up to the siding and the panel is about a foot above the siding - starting to wonder if that would violate code. Nothing would permanently be in front of it but it’d only be a foot or two above the hypothetical deck, and I’m not sure what is required for outside.

I think the deck would be considered the floor, and there's no minimum height requirement for the panel, so you should be fine so long as nothing is covered up.

Hey guys, dumb question. I'm switching out a switch for a z-wave switch. The line power goes into the light box in the ceiling, and a 14/2 runs from the bow to the switch. The switch just breaks the hot, like this: With this setup, I can't use a Z-wave switch. I can easily repull the wire between the switch and the light and replace it with 14/3. Then I can just connect it like this: This way, in the 14/3 - black is line - blue is load - white is neutral - ground is ground EDIT: Actually, it looks like this will work, and it's code for this reason. https://mrelectrician.tv/light-switch-wiring-diagrams/ Super-NintendoUser fucked around with this message at 15:15 on Sep 18, 2020 |

Yep, that will work. The code changed for switch legs a couple decades ago. You can't repurpose the white wire for light switches anymore, every switch box now needs a dedicated neutral, even if it's capped off. That's for future support for fancy switches that require neutrals, like motion sensors.

I have some work being done in my house so there's a bunch of removed dry wall, I'm using the chance to replace a bunch of old switches/wires that don't have ground with their grounded buddies. Just a question, some of my house is old armored cable, I can use that as the ground for smart devices, since they require hot, neutral and ground, right? Googling shows it's ok and it's not ok, so I'm not sure specifically. Electrically it works, though right?
