Anotace knihy

You can follow every step of a cable calculation and still not know why the answer is what it is.
That is where a great many electricians and students find themselves. The tables give a capacity, the guidance gives a correction factor, and a worked example arrives at a conductor size. Reproduce the steps in order and the paperwork is satisfied - but the moment a job departs from the example, the method has nothing left to say.
This book treats electrical installation as a subject to be understood rather than a set of procedures to be repeated. Every calculation is shown in full, with the units tracked and the reasoning stated, and every requirement is explained by the hazard it exists to control.
Sixteen chapters build the whole design and verification sequence in order - from fundamental principles, through conductor selection and protection, to the certificate somebody signs. Fifty figures carry the parts of the argument that words handle badly.

Inside you will find:

• The four constraints that jointly decide a conductor size, developed one at a time and then applied together
• Current-carrying capacity and correction factors; voltage drop and maximum circuit length
• Earth fault loop impedance, disconnection times and automatic disconnection of supply
• Earthing, protective bonding, earth electrodes and functional earthing kept properly distinct
• Residual current devices, arc fault detection and surge protection, including the failure that no ordinary test reveals
• Final circuits designed end to end: ring and radial, lighting and switching, fixed appliances and motor circuits
• Special locations, vehicle charging, solar photovoltaic systems and battery energy storage
• Inspection and testing in the prescribed order, with certification, classification codes and periodic reporting
• Worked examples and practice problems with full solutions in every chapter, plus four appendices, a glossary and a full index

Written for apprentices and college students, qualified electricians returning to study, technicians, designers and lecturers. Plain British English, current United Kingdom practice, and terminology used strictly throughout.
Open it at the constraint that has been troubling you, and start building the understanding that turns a procedure into a judgement you can defend.
