The kicker to slats is that at some point, they started making these plaster backing boards that replaced wooden slats, and then the installers had to plaster over those backing boards for the finishing coats. Those plaster backing boards are what eventually led to development of the gypsum/Sheetrock walls used in homes since the mid-60s. I think I have those plaster backing boards because I never meet the change in resistance you get when drilling into wood.The slats suck too. Depending on how pointy your anchor is you may need to get creative when installing it.
Ok electricians, I think I know the answer to these questions, but I'm curious.
Mid-90s house. Looks like some (all? TBD) of the light switches are not grounded. All of the ground wires from the romex are nutted together, so outlets and the lights appear to be grounded. But nothing is grounding the actual switches. All switches are in plastic JBs, so they're not grounded via the JB. This looks to be original to construction so it had to have passed inspection.
1. Was this indeed standard practice?
2. Is this generally safe? Or should I open up all the switches and ground them ASAP?
3. Is it required by code now? I assume so.
(Notes: we're replacing all of the outlets and switches, so I'll eventually get around to it. All of the actually outlets appear to be grounded, but I'll be inspecting and testing every one of them as we replace them.)
Friend on FB talked to a master electrician. He said 1999 was the last year you could have it not grounded. 2000 NEC changed that.
Now it's touch it, bring it up to code.
And I'm not concerned about the outlets in general. Home inspection said they were all grounded. One had reversed polarity but it's not a super huge concern IIRC.
The big concern for me is AFCIs. When those come down in price, I'd like to swap everything in the breaker panel.
yeah, check it with a meter. Non contact testers can make you believe there is power when there isn’t.Ok, new problem.
I have a hallway light switch that has 1X/3 (don't know if it's 12 or 14) Romex plus ground. Operates normally with what I assume should have just been a simple two-wire cable with ground.
This isn't a three way light circuit as far as I know, HOWEVER, this was a three way switch with all four wires attached. One hot, one traveler hot, and a switched line that only goes hot when the switch is on.
So here's where it gets bizarre and a bit scary. The other end of the hallway has a light switch that I was told used to control an attic circulator. But when I opened up the switch, it too was a three way switch with all four wires landed. But all three wires behind this switch are always hot no matter if I turn that switch on or off, or if I turn the other hallways switch on or off. No matter the configuration.
now, I've come to the conclusion that this is indeed NOT a three way circuit, fine. However, why would you have 12/3 romex run to a hallway light switch? This isn't connected to any other load other than a single light fixture as far as I know.
And why would all three wires in the other switch be hot? That doesn't make a lick of sense. I underhand that neutral isn't necessarily zero electricity, especially if it was a shared neutral somewhere up or downstream. I just don't understand why the red and black would also shot hot using a non-contact sensor.
Any ideas?

Yeah my house had a lot of work done when those tamper resistant outlets were first mandated and... they become adult-proof as much as child-proof. Supposedly the newer ones are much better?
I assume no permit for the work you are doing? Why would you put in tamper proof recepts?
Update:
New outlets and switches are starting to go into the kitchen. My god what a difference the Leviton Decoras make. I'm sure 99% of it is just the switch from almond to white, but they look fantastic. I really like the screwless faceplates. I still haven't swapped the disposal/dishwasher circuit out yet, but having the switch for the disposal next to an upgraded outlet makes the difference even more stark. Million dollar upgrade.
Also replaced the GFCI on that first circuit and really like the newer style that self tests regularly and has led indication. It's a couple bucks more but whatever.
I also found an outlet that had the line and load crossed across the outlet (hot line + neutral load on one set of posts and vice versa). Yikes. I'm not entirely sure it was something that would result in a burn the house down situation, but glad I fixed it. Now everything tests correctly. Plus now I know which outlets go to which circuit so I can update the labeling in the panel. I wouldn't have done it this way, but it still makes sense in the end.
My only gripe about all of this is that the new tamper resistant outlets can't be tested with a traditional single prong contact tester. Didn't think of that when I bought it :-/
Well done!
