Hello, I’m back again. A couple small questions this time, nothing major. But I do have a fun story to tell to explain one of the questions. I’ll put all the questions in bulk at the end though for those who don’t care.

For the story, I ran a new circuit for the lights in my basement. I got that project done fine and it works exactly as expected. But on the last step, when I hooked up the breaker I noticed the 15 amp single pole breaker above it had a white wire, not a black. Ok, not the biggest issue. I just need to figure out where it goes and reverse the wires on the circuit because I thought they had the black on the ground bar instead of the neutral. Instead the black wire went to a 20 amp single pole breaker. But it gets worse.

That side of the house has a lot of electrical stuff that doesn’t work. Several outlets, outside lights etc. it really could’ve gone to anything. But what it went to I wasn’t expecting. We have an electric radiator in our bathroom that hasn’t worked since moving in. I never payed attention because even on the really cold days the bathroom stayed warm since the rest of the house is fine with heating. Turns out the radiator, which requires a 220v circuit on a double pole breaker, was wired with a 12/2 romex NM wire and wired to 2 single pole breakers…. So that’s disconnected now.

My question is, since the slots are pulled out of the panel can I leave these breakers in there not wired to anything? What is the proper way to close those up?

Also, I took out some fluorescent lights and moved them from the window to the center of the room. In doing so I have a good bit of extra cable. It’s not Romex, but it is 600v NM cable. It’s the black rubbery coating. Is it worth saving this in case I need wire for a spare project or is there some kind of risk to using the old cable?

Hello, I’m back with another question. Everything a read is telling me yes I can, but it really does not feel right so I’m gonna ask here for good measure. Can I run electrical wire through fiberglass insulation?

In several rooms upstairs the wire comes out of the center of the ceiling then goes across to the window where a fluorescent tube light is installed. Below all that is a drop ceiling tile with insulation packed on top of it. I want to take the fluorescent light out and put a normal light back in which is easy enough. My concern is running the wiring through the insulation. Everything says running it through insulated walls is fine and the insulation itself says it’s non-combustible. But can someone confirm that I’m reading the right stuff?

There’s a gap between two pieces of insulation that I want to run the wire between. Picture attached. Not sure how old the insulation is if that is important.

I posted on here the other day about some suspicious 240v cable and followed the recommendations to replace it. I was already leaning that way but was kind of hoping to be told I was overthinking it. But you all confirmed what I thought. I ran close to 25’ of 10/2 cable from the second story to the basement. Nothing is wired yet because it is late and I don’t want to turn on the main breaker.

My step dad let me borrow a 50’ fishing tape and 10’ endoscope which were really helpful. I did not have to cut any walls!

Hello,

I have been doing a lot of work remodeling a house I bought. The house was in really rough shape so I was expecting a good bit of work but the last owners laziness and incompetence has really made things worse.

They had the house split into two apartments and we are converting it back to a single home unit. We knocked out a wall and installed new stairs to connect the top and bottom floors. Next we are converting the upstairs kitchen to a laundry room. We have been using the makeshift room for a few months, but we are getting a new washer and dryer. Our current dryer is a compact electric dryer that runs on a 120v outlet. The new will be a standard electric dryer and need a 240v outlet. There is 240v outlet in the room for a range. I am going to pick up a new breaker from lowes with the proper amperage but wanted to check everything else first and I think I ran into an issue with the wire itself.

There are 3 wires, which matches the outlet so I am assuming it is supposed to be 2 hots and a neutral. However, upon closer inspection there is no insulation on the neutral. I peeled back more of the larger insulation around all 3 wires but the neutral wire is uninsulated like it was a ground. Now, I have encountered this in the house elsewhere. Most of the outlets have grounds cut off, but a 3 way switch didn't have the second hot wire so they used the ground as the second hot. I got that "fixed" (I unhooked everything and made it a single switch/light circuit and eliminated the second switch). But I don't know of any 240v wire combinations that would only be 3 wires and include a ground. The wire is definitely thick enough to be 240v wire and each individual wire has multiple "threads" like a 240 wire would. But it is older wire as well so I am not sure if it is just that old that they didn't insulate neutrals when they did this. Is this wire safe to use?

A second, and more minor question, deals with a separate circuit. The house electric is still split and I pay 2 bills, one for upstairs and 1 for downstairs. The upstairs does have an outdoor AC unit on it as well that was installed after we moved in by an HVAC tech so I am trusting that to be installed right. But the entire box for the "upstairs" has 4 breakers. There is a 50amp, 40amp, and 20amp double pole breakers and a 10amp single pole. The 10amp controls a single light and one of the 240v breakers controls the AC. Another controls the range/future dryer outlet. The The 20amp double pole controls everything else upstairs which is ALL 120v. There are a few lights and all of the outlets. Is that safe? Is there a reason to do that? The upstairs is pretty small if that makes a difference, I have just never seen a double pole breaker used for a 120v circuit even if it is pretty large.

Edit: I made the original post on my PC due to the size but I’m adding some pictures from my phone

Edit 2: I am going to buy and run new wire with the new breaker. I showed a picture to my dad and he said nothing matters because that’s an aluminum ground which means the wire needs replaced due to its age regardless. So even if it’s wired wrong now, I am stripping the wire out and putting a new wire and breaker in so it should be done right

Reverse image search says Russian Leather Beetle but I live in Western Pennsylvania of the USA which it says they aren’t native to. Any ideas?

Hello,

I am looking to buy a house with a lot of work that needs done. I am hoping to learn a lot from the experience so when I am living in it I can fix more myself rather than pay someone else to get it done. One of the first projects is going to be adding an internal staircase. The home used to be single family, but was converted a few owners ago to a duplex. When they did this they removed the stairs connecting the top and bottom floors. I plan to add that back in and make it single family again.

For the project itself, my step dad will be there to help install the stairs. But I don't want to fully rely on him, even though he does know what he's doing. We have done multiple, simple, project together before including installing multiple decks. The stairs for those were only 4-5 steps and pre-cut at Lowes though so I don't think there is much to take away.

The plan is to install the stairs where the old staircase used to be as I think that will make the most sense, but if I am wrong about that please explain why so I can consider that when viewing the house this week.

What I would like to know is when I am at the house next is what should I look for, how do I calculate what all I will need, what I will need, and if there are any good sources online for this kind of project.

What should I look for:

I am pretty sure the best place to build the stairs is going to be where they already were, but what should I look for that will tell me there is a problem that will arise?

How do I calculate what all I will need and what I will need:

I know I need wood, screws and brackets. I am sure 2 boxes of screws will probably be enough, and a trip to the hardware store will be easy for that. Same with the brackets. But how do I calculate how much wood I will need? What size boards do I use for each component? Will I need anything else?

Are the any good sources online:

My step dad is really handy with this stuff and I know he isn't going to let it get done wrong, but it's a struggle planning stuff ahead with him. When I ask him what I will need, he gives answers like "it depends" or "a lot" but he doesn't go into specifics. I would like to research a good bit on my own so when we do actually get together to do this he just needs to come over and help build it which is what he is great at.

I tried looking at YouTube and some google searches, but not much luck other than this wikihow (https://www.wikihow.com/Build-Stairs) which seems pretty comprehensive but I would like more than one article for a project this big. As for YT, it was videos on building prefab stairs and adding them to a home, or refinishing a current stairway, neither or which apply. If someone could supply a good website, or even a YouTube channel that I did not see I would greatly appreciate it.
