VERIFICATION AND DESIGN OF ELECTRICAL INSTALLATION: A COMPLETE GUIDE FOR ELECTRICAL INSTALLATION (MORGAN, CHARLES)
Publisher: UNKNOWN
There are many electrical operatives who, quite innocently I am sure, select wiring systems based on the old adage of 'that's the way it's always been done' or 'we always use that size of cable for that circuit' etc. Unfortunately, this approach, except for a few standard circuits, is quite wrong. Each wiring system should be designed to be fit for purpose and involves more than arbitrary choices. The intention of this book is to illustrate the correct procedure for the basic design of installations from initial assessment to final commissioning.Any design of electrical installation must be primarily concerned with the safety of persons, property, and livestock. All other considerations such as operation, maintenance, aesthetics, etc., while forming an essential part of the design, should never compromise the safety of the installation. The selection of appropriate systems and associated equipment and accessories is an integral part of the design procedure, and as such cannot be addressed in isolation. For example, the choice of a particular type of protective device may have a considerable effect on the calculation of cable size or shock risk, or the integrity of conductor insulation under fault conditions. Perhaps the most difficult installations to design are those involving additions and/or alterations to existing systems, especially where no original details are available, and those where there is a change of usage or a refurbishment of premises, together with a requirement to utilize as much of the existing wiring system as possible. So, let us investigate those parts of the Wiring Regulations that need to be considered in the early stages of the design procedure
