Motor Control Centre (MCC) Panels

The load being placed on the motor under normal and abnormal operating conditions is very seldom consistent. In fact, some feeders are always in a continuous running state while some feeders are going to be starting with significant amounts of torque, and then finally on a rare occasion there are feeders that are going to be inside a plant for emergency service only.

In order for a manufacturing facility to have production without the need for operator intervention, motors must be installed with motor control centre panels that enable these different styles of feeding a motor to be managed in an effective manner.

At Perfect Automation & Innovation, we consider feeder philosophy, maintenance strategy, and future motors being added to the facility before designing the layout of the MCC panel — not simply how many starters are being included.

We install safe access and quick isolation provisions for each MCC compartment. The MCC compartments are located in the correct configuration (DOL, star-delta, soft start, and VFD) to ensure complete separation of power and control circuits. Correct busbar sizes are selected based on current loads and estimates of load growth to ensure no temperature rise when the facility reaches maximum production level.

Easy fault identification and tracing of control wiring is accomplished by routing the wires correctly. Indications, local/remote selector switches, and interlocks are all located as requested by the operator for their actual running conditions. Adequate cable alley area allows for the termination of large motor feeder cables without any congestion.

Thermal performance, short circuit-withstand capability, and functional sequence are verified at the time of test. Draw-out or fixed feeder option from service strategy is available. Therefore, all MCC panels manage multiple motor loads effectively, minimize maintenance downtime, and operate continuously throughout large industrial manufacturing facilities and utility systems, providing a safe work environment to employees and end users alike, while helping to contribute to reducing carbon emissions from our earth.
