Modular Power Houses Built for Fast Deployment and Critical Reliability
At Pinnacle Power & Controls, we engineer prefabricated switchgear buildings (also known as E-Houses) that streamline deployment and protect electrical infrastructure in mission-critical environments. These fully integrated, factory-built enclosures house low- or medium-voltage switchgear, motor controls, metering, relays, SCADA panels, HVAC, and fire protection — all prewired, tested, and ready for drop-in installation.
Whether you’re supporting a power generation site, utility interconnect, oilfield distribution, or remote treatment plant, our modular buildings reduce construction timelines, simplify commissioning, and ensure safe, code-compliant installations. Every system is designed to your one-line diagram and voltage class, with custom footprints, NEMA-rated enclosures, and AHJ-ready documentation.
Pinnacle’s E-Houses are built in the U.S., FAT-tested, and delivered on skid or trailer — ready for immediate deployment across high-demand sectors.
What Is a Prefabricated Switchgear Building?
What Is a Prefabricated Switchgear Building — And Why It’s a Smarter Way to Deploy Power
A prefabricated switchgear building — also called an E-House or modular switchgear enclosure — is a fully assembled and pre-tested electrical room built off-site, designed to house your facility’s low- or medium-voltage switchgear systems. These buildings are engineered to be transported and installed as a complete unit, significantly reducing on-site construction time, labor costs, and commissioning complexity.
At Pinnacle Power & Controls, our prefabricated buildings are custom-engineered to your one-line diagram, utility requirements, and application needs — whether you’re interconnecting with a 15kV grid or managing 480V process power. Each structure includes environmental controls (HVAC), fire suppression systems, SCADA/control integration, lighting, and access security — all installed, wired, and tested at our U.S. facility.
By consolidating procurement, integration, and testing under one roof, we eliminate the coordination headaches of multi-vendor site installs. Our switchgear buildings arrive AHJ-ready, fully documented, and ready for immediate hook-up — especially critical for power-critical sectors with tight timelines.
Types of Prefabricated Switchgear Buildings We Offer
Engineered, Pre-Tested Switchgear Buildings — Built for Your Power Infrastructure
At Pinnacle Power & Controls, we design and manufacture prefabricated switchgear buildings tailored to your electrical system, voltage class, and site footprint. Whether you need a walk-in metal enclosure for medium-voltage switchgear or a skid-mounted E-House for rapid deployment in oil & gas fields, our solutions are fully customizable — from HVAC, lighting, and fire protection to internal wiring, busbar runs, and SCADA integration.
Each unit is factory-integrated, QA-tested, and delivered field-ready with complete documentation and support. We build in compliance with UL, NEC, ANSI C37, and local utility interconnect requirements, ensuring a seamless handoff from production to commissioning.
Modular Multi-Room Buildings
Multi-section buildings for large-scale power systems or integrated control gear (MCCs, drives, switchboards). Designed for segmentation, safety zoning, and scalability.
Walk-In Switchgear Enclosures
Fully enclosed, climate-controlled metal buildings designed to house 480V or 15kV gear. Ideal for permanent facilities like substations, water plants, and manufacturing control centers.
Containerized E-House Solutions
Reinforced ISO-style containers repurposed and outfitted as medium-voltage switchgear rooms. Used for global transport, temporary power, or harsh environments.
Skid-Mounted Switchgear Rooms
Portable, pre-wired structures mounted on steel skids for quick transport and deployment — ideal for modular sites, oilfields, and emergency projects.
Industries & Applications for Prefabricated Switchgear Buildings
Purpose-Built Switchgear Buildings for Power-Intensive Industries
Pinnacle Power & Controls builds prefabricated switchgear enclosures that power some of the most demanding industrial environments across the U.S. Whether installed in a utility substation, an oilfield compressor site, or a mission-critical data center, our modular buildings are engineered to deliver safe, compliant, and scalable power distribution in the field.
Each building is designed around your voltage class, fault current specs, environmental conditions, and industry-specific standards. From Class I Div 2 oil & gas enclosures to NEMA 12 climate-controlled rooms for food processing, our E-Houses reduce on-site labor, speed up commissioning, and protect equipment in even the harshest conditions.

Why Pinnacle for Prefabricated Switchgear Buildings
Engineered, Integrated, and Delivered — The Pinnacle Advantage
At Pinnacle Power & Controls, we deliver more than just prefab metal buildings. We deliver fully integrated switchgear solutions, custom-engineered for your voltage class, protection scheme, and layout requirements. Every E-House is UL-listed, NEC/ANSI-compliant, and built with industrial-grade materials designed to endure harsh environments and meet AHJ approval.
Our team interfaces directly with your engineering staff, EPC firm, or utility provider to ensure that the building, gear, wiring, HVAC, and protection elements all work together, reducing install time, site risk, and rework. Whether you’re sourcing a generator switchgear enclosure, motor control building, or 15kV utility interconnect, Pinnacle delivers power distribution infrastructure that’s truly plug-and-play.

FAQs — Prefabricated Switchgear Buildings
Yes. All integrated switchgear is UL 891 (low-voltage) or UL 1558/ANSI C37 (medium-voltage) certified. The building assemblies themselves are built to NEMA and NEC standards and ship with one-line diagrams, nameplate data, and labeling for AHJ approval. HVAC, fire protection, and internal lighting systems can be customized and code-aligned.
Absolutely. While we fabricate most switchgear in-house, we can also integrate specified brands or owner-furnished gear, including breakers, relays, UPS systems, SCADA panels, and PLC racks. Let us know your BOM or drawing set, and we’ll coordinate accordingly.
We support a wide range of footprints — from small MCC buildings to multi-section 40’–60’ modular rooms. We engineer to your site’s crane-lift, skid-mount, or pier-mounting needs. Electrical clearances, working space, and aisleways are maintained to NEC Article 110 and ANSI C37 standards.
Each building undergoes QA and FAT (Factory Acceptance Testing) — including insulation resistance testing, relay checks, breaker trip verification, and continuity tests. We ship fully labeled with wiring schematics and can offer on-site commissioning services upon request.
Typical lead time is 6–10 weeks, depending on complexity and gear type. Rush builds, repeat layouts, and pre-approved designs can be completed faster. Skid-mounts and lift-in buildings may deliver sooner than pier-foundation installs.
