PDC Enclosures
A motor control center (MCC) enclosure is a building that forms part of an electrical motor control center used to manage multiple electric motors from a centralized location. For engineers, project managers, and utility procurement teams, an MCC enclosure must ensure the reliability of the equipment inside by supporting protection, operation, and long-term maintenance.

RDI Enclosures & Systems combines MCC enclosure manufacturing with in-house engineering and equipment integration to deliver solutions built around specific electrical, environmental, and site requirements. Part of The RDI Group, we draw on more than 100 years of industrial and engineering experience. From our 220,000-square-foot facility in Itasca, Illinois, RDI Enclosures designs and manufactures prefabricated, modular, and site-built solutions for customers in electric utilities, water, communications, energy, mining, transportation, and other industrial markets.
MCC enclosures protect critical electrical equipment from weather, contaminants, temperature extremes, and other site conditions. MCC enclosure systems also centralize equipment used to control and protect motors, such as circuit breakers, contactors, overload protection, motor starters, drives, controls, and busbars for electrical power distribution, with each device often located in the enclosure or control panel.
RDI offers MCC enclosure products and support across the full project lifecycle, from design and engineering through fabrication, equipment integration, testing, delivery, installation, and ongoing support. This turnkey approach gives project teams one resource for coordinating the MCC enclosure and the systems it protects for the intended use.
RDI manufactures prefabricated E-Houses and MCC enclosures with equipment installed, tested, and ready for installation or startup before shipment. HVAC, lighting, electrical packages, fire suppression, alarms, controls, and security features can be incorporated according to project requirements. This approach offers ease in the field, as prefabrication can reduce installation time significantly, reduces downtime, and simplifies setup.
More than 20 wall panel configurations are available so each MCC enclosure can match site conditions, equipment layouts, and architectural requirements, making the design suitable for a wide range of applications. Prefabrication is particularly valuable for utilities, remote facilities, and projects with limited onsite construction schedules. MCC enclosures can accommodate arc-resistant MCC equipment that provides arc-flash protection and redirects arc-flash energy away from operators.
Knock-down MCC buildings can be preassembled at RDI’s facility, disassembled for transportation, and reconstructed onsite, making them practical as MCC enclosures where shipping dimensions or site access create logistical constraints.
Successful MCC enclosure projects require early coordination of equipment dimensions, utility service, transformer capacity, fault current, maintenance clearances, transportation, and site access. Applicable NEC requirements, local codes, environmental ratings, and project specifications should also be addressed during engineering, so MCC enclosure selections consist of the right type, wiring, and power supplies for the intended applications and protection needs, resulting in a better fit for the project.
RDI’s in-house capabilities allow electrical equipment, HVAC, controls, lighting, and other systems to be integrated before delivery. Factory testing can help identify issues before the building reaches the site and simplify final installation and commissioning. Intelligent MCC variants can integrate sensors and communication protocols for advanced monitoring and control.
RDI approaches MCC enclosure projects as long-term relationships. Collaborative engineering, lifecycle planning, equipment access, future maintenance needs, and post-delivery support can all be considered during development. This approach helps customers receive an enclosure that supports today’s installation while providing practical value throughout the equipment lifecycle.
RDI Enclosures & Systems delivers complete turnkey integration for motor control center enclosure installations, combining custom enclosure engineering with factory-installed HVAC, fire suppression, electrical systems, and nationwide installation support.
Rather than simply supplying a MCC enclosure, RDI works as a long-term project partner, collaborating with engineering teams from initial design through commissioning and future facility expansions. This integrated approach helps customers deploy reliable, fully coordinated motor control center enclosures that reduce field labor, simplify startup, and support safe, efficient industrial operations for decades.
