I know its a pain, but many electricians will be buying the new regs book. I've been browsing one particular site and wondered what best to buy with the new yellow BS7671 regs. You guys refer to the IT "OSG" book a great deal, but I've noticed another book being sold with BS7671 called "site guide" by NICEIC. Are they basically the same? I've also been trying to see if any other books are available for special locations etc, but drawing a blank so far, any pointers please?
