With in-house engineering expertise, streamlined production processes, and access to stocked components, we help customers reduce lead times without compromising quality or code compliance.

When your project requires dependable power distribution equipment built around real-world jobsite demands, MCXP delivers practical, compliant, and responsive switchboard solutions.

UL891 switchboards are low voltage electrical distribution systems designed to safely distribute power throughout commercial, industrial, and mission-critical facilities. These switchboards are built and evaluated under Underwriters Laboratories Standard 891, which establishes safety and performance requirements for switchboard construction.

In practical terms, UL891 helps ensure that a switchboard is built to recognized standards for electrical safety, durability, and performance. These systems are commonly used where dependable power distribution is essential, including data centers, manufacturing facilities, infrastructure projects, healthcare environments, and large commercial properties.

A UL891 switchboard typically includes breakers, bus bars, metering, overcurrent protection, and other electrical components arranged in a configuration that matches the facility’s power distribution needs. Because every project has different electrical requirements, many UL891 switchboards are custom-built to meet specific voltage, amperage, layout, and enclosure requirements.

UL stands for Underwriters Laboratories, an independent organization that develops safety standards and evaluates products for compliance. The number 891 refers specifically to the UL standard for switchboards.

For engineers, contractors, and facility owners, UL891 provides confidence that the equipment has been designed and built according to established safety and performance criteria. This is especially important for electrical systems that support critical operations, high loads, or continuous-use environments.

UL891 switchboards are often specified for projects where compliance, reliability, and long-term performance are non-negotiable. Choosing the right switchboard partner helps ensure that the final build aligns with project requirements, electrical specifications, and applicable code expectations.

UL891 switchboards are commonly used in applications where reliable power distribution is critical, including data centers, manufacturing facilities, and infrastructure projects.

With in-house engineering capabilities, MCXP can quickly adapt switchboard designs, accommodate project changes, and support custom configurations. This approach reduces delays, improves coordination, and ensures each switchboard meets exact project requirements.

MCXP Solutions operates a UL891-certified manufacturing facility, meaning every switchboard we produce meets the recognized safety and performance requirements for industrial-grade power distribution.

This certification covers construction, dielectric strength, short-circuit ratings, and temperature rise limits—ensuring your equipment performs safely and consistently under load.

With UL891 compliance, you can trust that your system is built for durability, code conformity, and long-term safety.

MCXP Solutions supports a wide range of applications, including industrial facilities, mission-critical infrastructure, and data centers. Our switchboards are designed to handle high electrical loads, evolving compliance requirements, and continuous operation demands. 

From new construction to facility upgrades and emergency replacements, our switchboards are designed to support critical power distribution needs across diverse environments. MCXP Solution's UL891 switchboards support a wide range of industries and facilities, including:

UL891 switchboards are designed for low-voltage power distribution, while switchgear is typically used for medium-voltage systems and includes additional protection features such as circuit interruption and fault isolation.

Switchboards are commonly used in commercial and industrial facilities, whereas switchgear is used in higher voltage applications such as utilities and large-scale infrastructure systems.
