And more generally, the difficult part about building electricity is code. Codebooks are absolutely huge, difficult to read, and can vary by locality (not just by country or state but actually at the municipal level). I just don't have it in me to try and memorize a huge code book just so I can do a bit of wiring around the house (already need to memorize a bunch of standards in my day job as a mechanical engineer).

- deepspace 4y agoThe way 3-way switch wiring is presented in codebooks and electricians' manuals is 'weird' in a way that makes it very hard (for me) to understand. I am a qualified electronics engineer and I would much rather analyze some obscure analog circuit than try to understand someone's 3-way switch diagram.
