MOTOR CONTROLS AND STARTERS (LOW-VOLTAGE)4.5 days
3.6 CEUs
Lecture
8:00am - 4:30pm, the final day ends at 12:00pm Tuition USD $1500 The low-voltage motor control center is a key element in electrical control systems because of the vital operating role they play in controlling motors and production processes. Over the years, MCCs have evolved from cabinets that housed basic electro-mechanical devices such as circuit breakers, contactors and overload relays to centers of automation that may include variable frequency drives, starters and programmable controllers. Because failure of electrical systems - specifically MCC-housed equipment - can present a serious hazard to personnel and property, a thorough understanding of MCC maintenance and testing is essential.
