I notice that Frank has produced a nice article about Electrical Safety Testing (with emphasis on the type of situations sometimes encountered in so-called "developing nations").

See here. smile

Frank has also added two more pages on related topics:-

1) Earthing System and RCD
2) How to Connect a Mains Plug

I haven't got around to studying them yet, except a quick look at the pictures in the last mentioned. I (and no doubt, Frank as well) would be interested to hear opinions on that one (especially the merit of tinning the ends of wires; and the choice of tool [side-cutters] used, etc.). And what about the Hint at the end! smile
