I feel your pain. The simple truth is that having a degree in Electrical Engineering is actually a detriment in this case. The NEC, and permits and inspections are a part of civilization. In engineering speak, most of the NEC is orthogonal to electronics. The NEC prevents electrical anarchy. That's all it is for and that's what it does. Anarchy in ...

The normal rule in the USA is: You can work on your own home without an electrician's licence, but you can't hire yourself out to others. Permit requirements don't change. So sketch out what you want to do and take it down to your local building authority. The permit may take some time to get, but won't be expensive compared to your salary. Given that ...

It's not a "roof frame"; it's a truss. Its purpose is to keep the beam below it straight.

It's your house, do what you want. This isn't England/Soviet Russia/Germany (yet). You should see the "professional" electrical work in my house. Octopuses, bare wires on insulators, nails and romex. Every time I do anything I reduce the chance of a fire by 10%.

I wouldn't call the building department. I'd call your neighbor. Find out what the locals do. You can do what you want in your own house. Something as simple as a couple lights and a switch should be done before you've finished reading this post.

Contact your local building department, and ask them if this would require a permit, and if you can do the work yourself. That's the only way to know for sure, as different areas have different rules. You'll likely have to pay a small fee for the permit, and have the work inspected at different stages of the job (or maybe only once it's done). Most areas ...

NEC Article 362 I've copied the NEC portions that cover corrugated HDPE (High Density Polyethylene) conduit for your reading pleasure. The NEC differentiates between corrugated and non corrugated HDPE conduits by referring to corrugated HDPE as ENT and non corrugated as just HDPE. Non corrugated HDPE is not allowed at all in any buildings, whereas ...

It is okay to drill from below as long as you know, for a fact that you are not going to hit ANYTHING, otherwise go into the attic. The conduit can run on the floor of the attic but I would use a two hole strap and get it above the insulation . I would use a plastic pull box with a plastic cover, the backless may not give you the support that you need when ...

How much insulation? What size are the framing members in the floor? 1953 house, unless it has already been updated, is probably in desperate need of more attic insulation. That will cost you money all year, every year until it's done. Any house, plywood on top of the insulation will compress the insulation and cause it to lose effectiveness if the ...
