Motor control
Power distribution systems used in large commercial and industrial applications can be complex. Power may be distributed through switchgear, switchboards, transformers, and panelboards. Power distributed throughout a commercial or industrial application is used for a variety of applications such as heating, cooling, lighting, and motor-driven machinery.
Basic Motor Control
Wherever motors are used, they must be controlled.
In Basics of Control Components you learned how various control products are used to control the operation of motors.
The contactor’s contacts are closed to start the motor and opened to stop the motor. This is accomplished electromechanically using start and stop pushbuttons or other pilot devices wired to control the contactor.
The overload relay protects the motor by disconnecting power to the motor when an overload condition exists. Although the overload relay provides protection from overloads, it does not provide short-circuit protection for the wiring supplying power to the motor. For this reason, a circuit breaker or fuses are also used.
Typically one motor starter controls one motor. When only a few geographically dispersed AC motors are used, the circuit protection and control components may be located in a panel near the motor.
Motor Control Centers (MCC)
In many commercial and industrial applications, quite a few electric motors are required, and it is often desirable to control some or all of the motors from a central location. The apparatus designed for this function is the motor control center (MCC).
A combination starter is a single enclosure containing the motor starter, fuses or circuit breaker, and a device for disconnecting power.
Other devices associated with the motor, such as pushbuttons and indicator lights may also be included.

I want to share the latest technology trend of the motor control center
Do we require the use of energy meter per MCC?
Can i place MCC inside Low voltage Switch Room together with other Switchboards
Of course you can.
What is minimum spaces in between office table and MCC 600V?
dear sir,
at motor control unit have 1 regulator switch for connecting power supply what’s have name
Looking for information on MCC.
i want to set up MCC Panel with 10 motors and panelboard for lightings and power outlet.
Are there any set standards for numbering breakers in an MCC?
Hi can you please forward me the 4.3mb Basics of motor control centers because
I need to set up panels for MCC. for 12 electric motors
thanks for sharing useful information
please can you forward me the 4.3 MB Basics of Motor Control Centers
What is the maximum ambient operating environment recommended for a MCC?
