The Third Canadian edition of Electrical Wiring: Industrial is based on the 2009 Canadian Electrical Code (CEC). The CEC is used as the standard for the layout and construction of electrical systems. To gain the greatest benefit from this text, the learner must use the Canadian Electrical Code on a continual basis. In addition to the CEC, the instructor should provide the learner with applicable provincial and local wiring regulations, as they may affect the industrial installation. In addition to the accurate interpretation of the requirements of the CEC, the successful completion of any wiring installation requires the electrician to have a thorough understanding of basic electrical principles, a knowledge of the tools and materials used in installations, familiarity with commonly installed equipment and its specific wiring requirements, the ability to interpret electrical construction drawings, and a constant awareness of safe wiring practices. Electrical Wiring: Industrial builds on the knowledge and experience gained from working with the other texts in the Nelson electrical wiring series and related titles. The basic skills developed in previous applications are now directed to industrial installations. The industrial electrician is responsible for the installation of electrical service, power, lighting, and special systems in new construction; for the changeover from old to new systems in established industrial buildings; for the provision of additional electrical capacity to meet the growth requirements of an industrial building; and for periodic maintenance and repair of the various systems and components in the building.
