Residentcur writes: The popular press is full of stories about a recall of Sunset DIY books on home wiring. The recall is based on supposed bad advice contained in these books and going back three decades, but neither the government body responsible for it nor the publisher is willing to say what the problem is. In my view, it defies logic that this should be kept secret, since presumably many will fail to turn in these dangerous books and may well continue to follow their guidance going forward. No doubt someone in possession of such a book could scour it for at least a likely explanation for the recall. So far I have been unable to find even a speculation about the nature of the bad advice, amongst all the "this will teach you not to try to do it yourself" drivel. Can anyone enlighten this avid home electrician what to look out for in these books?
