Electrical installation calculations – jenkins b. d., mark coates

The publication of BS 7671 and its predecessors, the 15th and 16th Editions
of the IEE Wiring Regulations, led to a number of guides and handbooks
published by organisations involved in the electrical contracting industry.
These included the publication, by the Institution of Electrical Engineers, of
an On-site Guide and a number of Guidance Notes as well as several books
by independent authors and a considerable number of articles and papers in
the technical press. It also led to numerous instructional courses, seminars
and conferences.
It was thought that there was little else one could write about concerning
the Wiring Regulations, but after talking to a number of engineers in the
electrical installation contracting industry, Brian Jenkins gained the strong
impression that there was one need which had not really been satisfied. The
need was for a book that made considerable use of worked examples with
the absolute minimum discussion of the associated theoretical aspects.
In other words, a book which used such examples to show how one carried
out the calculations involved in circuit design for compliance with BS 7671.
