Electrician's Guide to the 17th Edition of the Iet Wiring Regulations BS 7671: 2008 Incorporating Amendment 3: 2015 and Part P of the Building Regulations

For years, electricians have relied on Whitfield's book. Unlike other publications, it does not assume that readers are fully conversant with electrical theory. This 4th Edition covers the latest Amendment 3:2015. It also benefits from the expertise of the co-author, Andrew Hay-Ellis (an established author + Chief Examiner at C&G).
