Publisher Summary This chapter provides project leaders with some understanding of electrical design and highlights the coordination of electrical design both with other disciplines and with utility companies, the suitability of materials, harmonics, and construction services such as field testing. The project leader should consult the electrical engineer to ensure that an adequate space is reserved for electrical equipment and to forestall interference with mechanical equipment and the building envelope. During the appropriate design stages, the project leader should also cooperate with the electrical engineers to ensure that the electrical drawings and specifications are complete and compatible with all of the other drawings and specifications. The project engineer should verify that electrical equipment, including light fixtures, does not conflict with structural elements or mechanical equipment, that necessary space and mounting provisions exist, and that the plans and specifications of the other disciplines are compatible with electrical systems such as voltage, phase, alarms, and controls. The electrical design engineer's role is to develop a system so coordinated that an overloaded motor would be removed from service before the motor insulation or bearings are damaged, and only the affected equipment would be removed from service. A properly coordinated overcurrent system would enable fault conditions to be isolated from the system without affecting the operation of other equipment. |
