17th Edition IEE Wiring Regulations Design and Verification of Electrical Installations Sixth edition by Brian Scaddan

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
basic design of installations from initial assessment to final commissioning.
It will also be of use to candidates studying for a C &G
2391-20 Design qualification.
This edition has been revised to serve as an accompaniment to the
new City & Guilds scheme and has been brought fully up-to-date
with the 17th Edition IEE Wiring Regulations.
