Custom Prefabricated MCC Buildings

Factory-Built MCC Rooms. Fast to Deploy. Built to Spec.
At Pinnacle Power & Controls, we engineer and manufacture fully integrated Prefabricated Motor Control Center (MCC) Buildings designed for rapid field deployment and long-term reliability. Whether you’re managing power distribution at a substation, compressor station, or processing facility, our UL 508A-certified MCC buildings deliver turnkey motor control in one climate-controlled, code-compliant package.
Built entirely in our U.S.-based manufacturing facility, each modular MCC building is customized to your voltage, enclosure, and integration needs — from 480V to 15kV, from low-voltage starters to medium-voltage ANSI C37 switchgear. We integrate VFDs, PLCs, SCADA systems, HVAC, and lighting in-house to minimize on-site work, reduce costs, and eliminate construction delays.
With faster lead times, sealed environmental protection, and a smarter factory-tested process, Pinnacle’s prefab MCC buildings are built to spec — and built to perform.
What Is a Prefabricated MCC Building?
A Prefabricated Motor Control Center (MCC) Building, also known as an MCC E-House or modular MCC container, is a fully engineered and factory-assembled structure that houses one or more motor control centers along with supporting systems like HVAC, lighting, protection relays, and automation hardware.
Unlike traditional MCCs that are field-installed piece by piece, prefab MCC buildings are delivered as complete, code-compliant units, saving weeks or even months in field construction, wiring, and commissioning.
At Pinnacle Power & Controls, each MCC building is custom-built around your electrical specs, equipment layout, and environmental challenges. Whether you’re working with Medium-Voltage MCCs for turbines or Low-Voltage MCCs for process lines, we design and fabricate your system in our UL 508A-certified panel shop and ship it as a turnkey solution — pre-tested, pre-wired, and ready to deploy.
These modular structures are ideal for remote job sites, hazardous zones, or mission-critical facilities where space, safety, and speed are paramount.
Engineering Capabilities of Our Prefabricated MCC Buildings
When your project demands a fast-deploying, fully integrated MCC solution, our prefabricated MCC buildings deliver.
At Pinnacle Power & Controls, we design custom prefabricated MCC buildings (a.k.a. E-Houses or power control rooms) that arrive on-site fully wired, tested, and ready for power-up. Each building is configured around your electrical layout, motor control logic, fault protection strategy, and environmental conditions.
From modular containerized rooms to permanent outdoor walk-in structures, our factory-assembled MCC buildings reduce site labor, eliminate scheduling conflicts, and support faster commissioning, while maintaining compliance with UL 508A, NEC, ANSI C37, and NEMA standards.
🛠 Core Capabilities
Each MCC Building is built-to-spec and can include:
Why It Matters:
With labor constraints and field challenges growing, prefabricated MCC buildings offer a turnkey motor control environment that speeds up your electrical scope, without sacrificing safety, inspection-readiness, or performance.

Built for the Real World — Industry Applications for MCC Buildings
Purpose: Showcase how these prefabricated MCC buildings serve different sectors, with real-world examples and internal links for further exploration.
From offshore oil rigs to utility substations, our prefabricated MCC buildings power critical infrastructure across the U.S.
At Pinnacle Power & Controls, we build each MCC around the demands of your environment, voltage class, and operational use case. Whether you’re managing mission-critical power or scaling plant automation, our engineered buildings simplify deployment and minimize field risk.
Common Industry Applications:
Why It Matters:
Industrial projects demand more than just panels — they need scalable, compliant, and field-ready MCC solutions that hold up in real-world conditions. Our buildings are built around your uptime, compliance, and safety requirements.
Standards, Testing & Compliance — Engineered to Code. Built for Inspection.
Purpose: Build trust by highlighting how Pinnacle’s prefabricated MCC buildings meet strict U.S. codes and quality standards, reducing risk, delays, and inspection failures.
At Pinnacle Power & Controls, every prefabricated MCC building is engineered, assembled, and tested by national and industry-specific codes. Whether you’re working under UL 508A, ANSI C37, NFPA 70E, or utility-specific mandates, we deliver documentation-ready MCC buildings that pass inspection the first time.
Our compliance-first design process includes:
Core Certifications & Code Frameworks:
UL 508A
All control panels inside MCC buildings are built and labeled in our UL-certified shop.
UL 347
(for medium-voltage applications): Medium-voltage MCCs within the building meet UL guidelines for motor controllers over 1kV.
ANSI/IEEE C37.20.7 & C37.20.2
Required for arc-resistant, medium-voltage MCC assemblies.
NFPA 70E / NEC Article 409 & 110
Electrical safety, arc flash mitigation, and panel labeling.
NEMA Ratings
Enclosures are built to NEMA 1, 3R, 4X, or 12 — matched to site environment.
AHJ-Ready
Our packages include testing documentation, drawings, FAT checklists, and installation guidelines.
