what get's me ,is some of this books were sold back as far as 1975 and they are just being recalled now? I am a retired electrician so I never had a reason to read any of these books but I found another post on this some time back (can't remember where.....CRS!)but by the illustrations they had I thought this was just isolated time someone did not double check what was being printed not something that had being going on for 30 -35 years!!
Makes you wonder how much DIY wiring that is out there that is not wired right that has the potential to hurt/kill someone or burn the house down. Scarey ......
