I have zero formal training. My dad showed me how to wire a circuit when I was 12. A wall outlet when I was 15. Other than that all other information I needed was found online. I didn't have anyone to guide me through my sub panel installation, but after reading here and other places I felt confident I could pull it off.
Electrical work such as this is very simple. As long as people use wire/outlets/etc rated for the current they will be using, which is very easy to determine most of the time its on the packaging... It is literally connecting wires together with a screw driver.
There is no crazy logic like a computer. We aren't even talking about wiring relay circuits.
120v has 3 wires. 240v has 3 or 4. They are color coded...
If this is over your head please dont proceed. im done
No doubt, I've done all my own electrical with backwoods training. I just thought the option I presented was a safe alternative to that. Rives made it clear I was wrong and I'm glad he stepped in and flexed his electrical prowess!
