For more than 30 years, students and practising electricians have relied on John Whitfield to take them step by step through the complexities of the Wiring Regulations in a clear, logical and helpful manner. His Guide is a recognised 'brand' and regarded over the years as the guide to the Wiring Regulations. Unlike other publications, it does not assume that readers are fully conversant with electrical theory. It assumes just a basic knowledge and introduces technical matter with brief easy-to-understand explanations. This 4th Edition of the Guide is a continuation of the bestselling series. It covers the latest Amendment 3:2015, such as auxiliary circuits, earth fault loop impedances protective devices, surge protection and outdoor lighting. As in earlier editions, all useful relevant details derived from other IET publications such as Guidance Notes, Wiring Matters, which might otherwise be overlooked by electricians, are included. Importantly the Guide also benefits from the most up-to- date, hands-on expertise provided by the co-author, Andrew Hay-Ellis, whose credentials are second-to-none.He is an established author of vocational electrical books and, amongst other functions, is a Chief Examiner at City & Guilds.
The authors understand that many readers might be sole traders, and so they try to spell out the financial implications and to suggest money saving action where this is possible. No legal jargon, no unnecessary details, comprehensive - yet practical, helpful and easy to put into practice.
