Custom Prefabricated MCC Buildings for Industrial Power Control
Modular MCC Control Rooms — Built Fast, Built Right, Built for You
At IEP, we design and construct purpose-built Custom Enclosed Motor Control Center (MCC) Buildings that redefine how
Power infrastructure is deployed. Our prefab MCC control rooms are engineered for code compliance, long-term reliability, and fast field deployment readiness, making them ideal for substations.
compressor stations, utilities, and process facilities.
Each unit is engineered around your voltage class, control architecture, and operating conditions. As a UL 508A and UL 347-certified manufacturer, we prewire, test, and integrate your MCC system solution in-house, reducing construction schedules and field risk. In short, we provide a customized, code compliant modular version of proven MCC solution.
What Are Custom Prefabricated MCC Buildings?
Custom Prefabricated MCC Buildings — also known as E-Houses or modular MCC enclosures — are complete, factory-assembled control centers housing motor starters, automation panels, power distribution gear, and environmental systems. These modular buildings ship pre-tested, code-compliant, and field-ready, saving weeks of on-site construction and commissioning.
We support low-voltage (480V) and medium-voltage (up to 15kV) MCC configurations, including VFDs, soft starters, SCADA connectivity, and PLC/HMI control. Each structure is engineered to handle thermal loads, arc flash risks, and environmental constraints without requiring field rework.
Core Features:
- Custom Electrical Layouts — Designed around one-lines, load schedules, and breaker coordination studies
- Fully Integrated Systems — HVAC, lighting, control cabling, SCADA, and safety gear installed and tested
- Sealed and Certified — UL/NEMA-compliant designs shipped with full documentation
Compliance and Standards for Custom Prefabricated MCC Buildings
We deliver MCC buildings that are compliant from the outset, with engineering, documentation, and labeling aligned to the most stringent industry codes.
Code & Quality Framework:
- UL 508A — Certified control panels for low-voltage MCCs
- UL 347 — Medium-voltage motor control assemblies
- ANSI/IEEE C37.20.7 / C37.20.2 — Arc-resistant switchgear
- NFPA 70, 70E / NEC Articles 409 & 110 — Grounding, labeling, LOTO, and arc flash protection
NEMA Enclosure Ratings — Site-specific environmental classifications (NEMA 1, 3R, 4X, 12)
FAT & Documentation Includes:
- Wiring schematics & panel schedules
- Breaker coordination and load analysis
- Relay logic testing and startup verification
- LOTO layout maps and foundation specs
- PE-stamped drawings and AHJ-ready submittals

Frequently Asked Question’s
How are prefabricated MCC buildings different from field-built rooms?
Our MCC buildings are assembled, wired, and tested off-site in a controlled environment, drastically reducing field work and construction risk.
Do these buildings support SCADA, PLC, and HMI systems?
Yes. We pre-install and test all automation hardware, ensuring smooth integration and communication from day one.
What’s the typical delivery timeline?
Standard delivery is 4–8 weeks, depending on system complexity. Rush options are available.
Are HVAC, lighting, and fire detection included?
Each unit includes climate control, emergency lighting, fire-rated insulation, and smoke detection — configured to your specs.
Can you meet utility or industry-specific standards?
Absolutely. We design around project specs, utility interconnection rules, seismic requirements, and AHJ mandates
