Commercial Electrical Wiring: Updated to the 1999 NEC

Commercial wiring uses more material, and the work is usually smooth, long-lasting, and more profitable than residential. This book covers practical on-the-job applications that are used for almost all wiring systems for commercial buildings: commercial construction documents, load calculations, electric services, transformers, overcurrent protection, wiring methods, raceway, boxes and fittings, wiring devices, conductors, electric motors, relays and motor controllers, special occupancies, safety, and support.
