Insulation is not a problem at all. My ceiling is brand new, sealed, with plenty of fresh insulation, and the house stays perfect temperature in all conditions. The topic is about attic temperatures and if there is any way to manage them. If I knew that putting in a fan would drop temperatures...

This is intriguing to somebody who wants to keep attic temperatures more reasonable. There's a lot of things that are safe to 120F, and lot of things that could cause trouble at 150F if they accidentally get put in attic storage. Are you talking about the foil-faced bubble wrap stuff? Did you...

A metallic raceway can often serve as a equipment grounding conductor, such that a dedicated ground wire is not required. Common cases include a 240v circuit in EMT, which requires only two wires. I am not an electrician I just play one on the Internet. Consult your local AHJ.

Many types of metallic conduit can be used as EGC. A low resistance ground is required. A ground wire is not. NEC 250.118

I'm in Southern Idaho, Climate zone 5B. We have dry summers over 100F, cold winters down into the teens, low humidity, and less than 12 inches per year of precipitation. Lots of sun, pretty big temperature swings between day and night. I built an addition, and I'm not sure the attic venting is...

I don't think any EVSEs require neutral. The 14-50 receptacle just became the convention for EV charging because it was the most common 50A receptacle used in North America by far. A 6-50 would have done just as well for EVs, but residential electricians don't just carry 6-50 receptacles around...

Where do you get incandescents nowadays? My inspector said pull-chain was not code compliant anymore, and made me put a switch in the hallway to turn on the attic light. I have a pantry closet with a switch like that, and I know from experience the switch gets left on all the time. At least in...

NEC allows you to use metallic conduit as ground, so it's true that you only need 2. My lathe run consists of two 12ga THHN wires in 3/4 EMT. Perfectly safe and code compliant.

Building code requires lights in accessible attics. But my attic gets literally 150F during the day (I've checked). All the LED light bulbs I can find are rated at 40C ambient max temperature, a far cry from the 70+C in my attic. The last thing I want is a light bulb melting down or catching...

I'm a big fan of drywall. It's cheap, relatively fire safe, infinitely patchable, and you can hang things anywhere on it. They key for a garage drywall is not to be sentimental about it and consider it an expendable surface to be consumed. The problem with drywall anchors is they aren't...

That's a duct boot. What you are looking at is the side inside the AC closet, where the AC air handler will be. There will be flex duct connected between the air handler and the duct boot. The other side of the wall is the living space where the air will blow out, and it will have a...

This is what the drywall looks like around my ducts. I think it should be better, both for looks, and to keep leaks out, but I don't know what to use. Caulk? Duct sealant? Drywall mud? The ducts are odd shape, so a round trim plate won't really fit.

No, and what's more, the same roofer ripped the peak open all the way to the end, as if he was going to run the vent the whole way, but then didn't install ridge vent all the way to the end. Further supporting the "ran out of material" hypothesis. You sound like a good builder that uses common...

My plans specify "Continuous ridge and soffit vents", but the builder didn't extend the vent all the way across the ridge. Before I push back on the builder for this, is there a legitimate reason to do this? If not the full length, how did he decide what length to install?

The beginning points are various locations I thought I might want speakers in the future. The end points are all in a central closet. I didn't do a lot of planning nor did I want to break the bank... just told them to put in speaker wire and run them to the closet just in case. Looks like I got...

This is how the contractor ran the wiring in my addition. The grey wires are all the speaker wires for what may become a home theater some day, and the blue is CAT6 ethernet cable. I don't think there's any problem bundling CAT6 cable, because I see it done all the time. I'm not sure about...

Can't expect any floor to stay looking new. A well-used floor is just a sign that you do work in your garage.

During construction of my addition, we had a downpour before the roof was on. Water was pooling in the second floor with nowhere to go, and it was starting to run into the house. The contractors drilled several holes to allow water to drain down into into trash cans on the first floor. It was...

The setup is still basically working perfectly. Shed lights work, my mower and tools stay charged no problem. The single flaw is the ecoflows won't solar charge during cold winter periods. I'm barely using power in the winter so it's actually a non-problem. But just to prove a solution, I put...
