Reading an old code book from the 80s and one rule blew my mind

Found my grandpa's NEC book from 1984. The ampacity for 12-gauge NM cable was 20 amps back then, not 15. That changes how you look at a lot of old wiring. Anyone else run into old codes that would fail today?

Guess grandpa's house was running on pure optimism.

That old house probably thought positive thoughts were a valid energy source. The wiring was held together by duct tape and hope. Honestly, it's a miracle the place didn't just politely catch fire one day. Some real "if we don't look at it, it's fine" logic going on there.
