Comment on The clueless people are out there among us
slingstone@lemmy.world 3 weeks agoWhat’s a good resource for learning about electrical engineering for people starting from nearly zero knowledge? I’d love to learn more so I don’t burn my house down if I want to, say, replace a light fixture in my house.

I’m not an EE. I apologize if I gave that impression. I just have an obsession with understanding anything I use on a regular basis, whether computers, smartphones, electricity, vehicles… Anything that does stuff, and I use it, I want to know how it does the thing that it does.
I’m weird like that.
I learned a lot from “Electrician U” on YouTube, along with a few others. Maybe worth a look. The scientific/physics side of things was more from watching other YouTubers (as to why it behaves the way it does), along with a fundamental knowledge that I learned from doing amateur radio stuff. Working in IT and having to deal with the power requirements of systems and making sure that we won’t blow a breaker under load… That helped motivate me to learn.
It all came to a head when we were deploying a network and server for a business that was still in construction of the facility. The electrician was going to run a temp line for our stuff so we could set up and be ready for opening day, and he asked how many amps we needed… I did a bit of a deep dive to figure out an answer for him, and I’ve been learning more and more since then.

Cool. Thanks for the direction. I’m curious about electrical stuff, and I’d like to be able to do some things around my house. There’s some DIY stuff online, too, involving building projects from old parts of appliances that interest me, but I realized quickly that I’d need some very good knowledge about electrical work to stay safe. It’s unlikely I’ll actually pursue the latter, but I’d like to at least know the how and why of my home wiring.

My recommendation is to maybe get some electrical safe tools, possibly some gloves that insulate against shocks, but definitely a good non-contact voltage detector, or NCV.
Check the circuit with your NCV before turning off the power, before working on the things on the circuit, and after turning on the power when you’re done (before you switch anything on). It helps keep you and your house from halting or catching fire.
… And always connect ground wires first.
Good luck.
