For teams comparing switchgear manufacturers, the priority is finding equipment that fits the project already in motion. Configurations from 400A–4000A can account for service requirements, breaker arrangements, metering, cable entry, enclosure needs, available space, and existing field conditions before production begins.
A 50,000 sq. ft. U.S. manufacturing and warehouse operation supports faster coordination between engineering, fabrication, assembly, testing, and shipment. In-house copper bus fabrication, CNC machining, UL 891 capabilities, and Siemens components help keep switchgear builds aligned with project specifications and production schedules.
Standard configurations typically ship in 4–6 weeks.
Keep procurement and installation schedules moving with shorter production timelines for standard builds.
Every system is engineered around applicable codes, safety standards, utility requirements, and project specifications. Clear documentation and compliance-focused manufacturing help support smoother approvals, inspections, and long-term performance in the field.
Switchgear and switchboards built to meet UL 891 requirements for safety, performance, and reliability.
Engineered around National Electrical Code (NEC) requirements to support proper installation and safe operation.
Switchgear and switchboards built to support BABA requirements for federally funded projects.

Switchgear can be configured around the voltage, amperage, phase, and wiring requirements of your application. Each solution is built to support reliable power distribution, code compliance, and long-term performance.
Additional configurations are available. Contact our team of experienced engineers to build a panelboard that fits your exact specifications.
Custom panelboards help organize branch circuit distribution around the specific loads, spaces, and operating needs of a facility. Each panelboard is built around project requirements, code considerations, and installation conditions.
Built for data centers, manufacturing, healthcare, commercial facilities, and infrastructure projects that require reliable low-voltage distribution, flexible configurations, and coordinated delivery.
High-performance electrical switchgear built for uptime & scalability
Efficient systems keeping production lines powered without downtime
Scalable power systems driving logistics, operations, and customer service
Custom electrical switchgear enhancing safety, efficiency, and tenant comfort
Built for data centers, manufacturing, healthcare, commercial facilities, and infrastructure projects that require reliable low-voltage distribution, flexible configurations, and coordinated delivery.
Standard lead times on switchgear configurations are typically 4–6 weeks, while custom builds may require additional time depending on complexity, components, and project requirements.
Yes. DEI Power manufactures low-voltage switchgear in the United States, with engineering, fabrication, assembly, and testing coordinated through its U.S. operation.
Shipping is coordinated around the equipment dimensions, destination, site requirements, and project schedule. Delivery details are reviewed as part of the order process.
Returns and exchanges depend on the equipment configuration, production status, and order terms. Contact DEI to review the specific requirements for your project.
DEI Power manufactures both indoor and NEMA 3R outdoor switchgear for applications requiring weather-resistant enclosures.
Equipment can be configured around breaker arrangements, metering, cable entry, bus requirements, enclosure type, footprint, and other project specifications.
Contact us to send available drawings, one-lines, amperage, voltage, breaker requirements, enclosure type, metering needs, and project schedule. Our team will review the information and help determine the appropriate configuration.
