The Guide to Electrical Maintenance provides guidance on carrying out maintenance activities and using good practice techniques. It examines the operational risks, mitigations and processes that may be used in carrying out electrical maintenance, and also provides insights and philosophies to ensure that electrical maintenance activities are not only safe, but are satisfactorily planned and properly carried out. The Guide also draws together key guidance from other IET inspection safety and maintenance titles to provide a practical overview for duty holders responsible for maintaining electrical systems, electrical contractors and building service engineers. Good maintenance regimes do not happen by accident: they need careful planning, proactive management and comprehensive reporting. The tone for good maintenance is also established beforehand by considerate design, intelligent construction and satisfactory commissioning. A good maintenance regime also has its part to play in a more sustainable world where correctly maintained electrical systems keep operating at their maximum energy efficiency and are disposed of correctly at the end of their lifecycle. This Guide is aimed at electrical contractors, engineering technicians, maintenance engineers and managers, design engineers, building service engineers and duty holders responsible for electrical maintenance.
