What Electric Equipment & Engineering does

Electric Equipment & Engineering Co. (EEE) is a privately held, family-owned manufacturer of electrical power management equipment founded in 1922 in Denver, Colorado. The company designs, engineers, and manufactures custom UL-listed power transfer, distribution, and battery management products, including automatic and manual transfer switches (50A to 5000A), the patented Panel One integrated load center (with 250+ design variants), battery disconnects (200A to 2400A) compatible with 165+ VRLA battery models, portable generator connection boxes and the combined Portable Generator One Box, EUSERC-compliant service entrance equipment, smart switchboards with Modbus building automation integration, and remote motor operators for Siemens 800-2000A breakers. Core technology is built around circuit-breaker-based transfer switches with microprocessor controllers developed since the 1970s, walking-beam mechanical interlocks, and custom mounting interfaces enabling rapid on-site installation.

EEE serves telecommunications (named customers include T-Mobile and Verizon), utilities and power providers, industrial facilities, OEMs, and alternative-energy owners, with thousands of systems installed across nearly all 50 U.S. states. The business operates a direct enterprise field-sales model: products are configured to customer specifications and priced via a quote-based process, with engineering support through the sales cycle, multi-year project cadence, and no public pricing or e-commerce. Revenue is generated primarily through one-time custom hardware sales supplemented by custom engineering and design services for low-voltage AC/DC industrial, commercial, and residential projects up to 600V AC and 500V DC.

The company has pursued end-market expansion into POD data centers, edge computing, and green/renewable energy in the 2020s, alongside ecosystem partnerships with Siemens and Russel/ASCO for switchgear integration. Ownership remains with the Morroni family, with no disclosed outside institutional capital, no public listing, and no disclosed financial metrics.

Expansion highlights5 records

Broad incumbents

• Eaton: Eaton is a broad incumbent in switchgear, transfer switches, switchboards, and power management products serving utilities, data centers, and industrial customers. Its breadth and global footprint make it both a competitor (against EEE's full product line) and a benchmark for UL 1008 / UL 891 / EUSERC-compliant offerings in EEE's core markets.
• Schneider Electric: Schneider Electric owns ASCO and offers a broad portfolio of switchgear, transfer switches, and power management solutions globally. It is both EEE's closest direct peer (via ASCO) and a broader incumbent in switchboards and BAS-integrated power equipment that competes with EEE's Smart Switchboard lineup.
• ABB: ABB is a major global manufacturer of low- and medium-voltage switchgear, transfer switches, and motor control centers serving utilities, industrial, and infrastructure customers. ABB competes with EEE in EUSERC-compliant service entrance equipment and integrated switchboards, particularly for utility and large commercial applications.
• Cummins Power Generation: Cummins Power Generation produces generator sets, transfer switches, and integrated power systems for commercial, industrial, and utility customers. Cummins competes with EEE in the backup power and transfer switch market, and is a natural alternative source for portable generator connection and transfer switch solutions.
• Kohler Power Systems: Kohler Power Systems manufactures generators, transfer switches, switchgear, and paralleling switchgear for mission-critical, commercial, and industrial applications. Its transfer switch portfolio (KOHLER Automatic Transfer Switches) competes with EEE's 50A–5000A transfer switches in many of the same telecom, healthcare, and data center use cases.
• Siemens: Siemens is simultaneously a strategic integration partner for EEE (Siemens WL breakers, SB3 switchboard formats, Modbus data tables) and a broad incumbent competitor across transfer switches, switchgear, and motor operators. EEE's EUSERC-compliant equipment and motor operators for Siemens breakers sit directly within Siemens's installed ecosystem.
• Generac Power Systems: Generac is a leading manufacturer of backup generators and automatic transfer switches for residential, commercial, and industrial markets. Its transfer switch product line directly competes with EEE's transfer switches and Portable Generator Connection Boxes, particularly in commercial backup power applications.

Direct peers

• ASCO Power Technologies (Schneider Electric): ASCO, now part of Schneider Electric, is the most direct comparable to EEE in automatic and manual transfer switches, bypass isolation switchboards, and power transfer equipment for telecom, healthcare, and data center customers. EEE explicitly integrates with Russel/ASCO bypass isolation products, confirming direct product overlap and a head-to-head competitive relationship in custom switchgear.
• Russelectric (Siemens): Russelectric, owned by Siemens, manufactures automatic transfer switches, bypass isolation switches, and power control systems for mission-critical facilities including hospitals, data centers, and utilities — directly overlapping EEE's transfer switch and switchboard portfolio. Like EEE, Russelectric is a specialist with deep UL 1008 listings competing against the major OEMs.

Emerging players

• Milbank Manufacturing: Milbank is a U.S. manufacturer specializing in metering, switchboards, enclosed controls, and EUSERC-compliant service entrance equipment — directly overlapping EEE's EUSERC and switchboard product lines. While larger in some segments, Milbank is a focused specialist comparable to EEE in custom utility-grade electrical equipment.
