- electricity, the legislations, criteria and codes of perform;
- assessment of common features;
- protection opposed to electrical surprise, thermal results, overcurrent, undervoltage and overvoltage;
- isolation and switching;
- the universal principles of kit choice;
- switchgear, protecting units and different gear;
- wiring structures (including the exterior affects on them and cable install methods);

2 of BS 7671:2008 require that persons and livestock are protected against injury, and that property is protected against any harmful effects, resulting from: • a fault between live parts of circuits supplied at different voltages; • overvoltages likely to arise from atmospheric events or from switching. 2 points out that protection against direct lightning strikes is dealt with in BS EN 62305. 4 are new to Part 1 of BS 7671. The first of these regulations requires persons to be protected against injury, and property to be protected against damage, as a consequence of undervoltage and any subsequent voltage recovery.
