Motor Circuit protection is a critical aspect of electrical system design. According to NFPA 70: National Electrical Code (NEC) Article 430, motor protection encompasses overload protection, short-circuit and ground-fault protection, conductors, control circuits, controllers, motor control centers, disconnecting means, adjustable-speed drive systems (such as variable frequency drives, or VFDs), and grounding. These guidelines are based […]
