I'm working in the trade as a sparky's mate but on large student accomadtion blocks. I've been doing it for around 10 weeks and I put trunking and baskets up and wire up bathroom pods but I dont know why im loading a feed cable to a box or anything and just wanted to know the basics before I go on a course, of why for example we use an neutral, live and earth why we use 2 core or 3 core, how to wire a ring main and stuff like that. Someone has recommended this book to me
Amazon.co.uk: "Reader's Digest" Wiring and Lighting Manual (Readers Digest): Books
So if that helps anyone I would like a few recomendations.
Thanks
