The demand for electrical switchgear has surged across nearly every industry. Major electrical OEMs nationwide are facing capacity constraints, leading to extended lead times for critical equipment.
At ASG Power, we recognize this opportunity to support customers who need high-quality, dependable switchboards delivered on schedule. Achieving UL891 certification marks a significant step in that direction. The certification confirms that our switchboards meet nationally recognized safety and performance standards, an assurance that directly benefits the engineers, contractors and facility owners who rely on them.
UL (Underwriters Laboratories) is a global organization that sets safety and performance standards for electrical equipment. A UL mark indicates that a product has been independently tested and meets the requirements of that standard.
The UL891 standard applies specifically to switchboards. Unlike component-level UL listings that cover breakers, bus bars or disconnects individually, UL891 certifies the entire assembled system. This ensures that all components function safely and consistently when integrated into a complete unit.
For customers, this certification ensures compliance with electrical code and regulations. Most authorities having jurisdiction (AHJs) require switchboards to meet UL891 standards; projects that fail to meet these prerequisites may fail inspection or require costly changes.
To earn UL891 certification, ASG Power evaluated and refined its entire build process—from design documentation and materials selection to inspection and testing.
Each switchboard design now carries verified ratings for voltage up to 1000 volts or less, and is intended for use in accordance with the National Electric Code (NEC) and other relevant North American standards. These requirements also cover switchboards for use on circuits having available short-circuit currents of no more than 200kA. Manufacturing procedures have been formalized and audited to align with UL’s requirements, ensuring that every assembly meets the same quality criteria.
The certification also enhances internal consistency. Detailed records, standardized wiring practices, and defined inspection steps mean each switchboard follows the same verified process from start to finish. As a result, we can deliver assemblies that meet the same quality expectations as large-scale electrical OEMs while maintaining shorter lead times.
Switchboards built under this standard can be used as standalone units or integrated into larger systems, such as skids or electrical houses. That flexibility allows us to meet a range of project needs and be more vertically integrated.
For customers, UL891 certification provides several clear advantages. It streamlines project approvals by ensuring the switchboard meets recognized safety and construction standards. Inspectors, contractors and end users can move forward with confidence that the product satisfies code requirements.
Certification also reinforces product reliability by confirming that each unit is manufactured under a documented and repeatable process. Consistent production reduces variability between builds and lowers the risk of field issues.
Further, UL891 certification shortens project timelines. Because we can now produce UL-certified switchboards in-house, our customers have access to compliant equipment without waiting for extended electrical OEM lead times, an important advantage for fast-moving projects such as data centers, utilities and large infrastructure builds.
UL891 certification represents more than a compliance milestone for ASG Power; it reinforces our approach to engineering, manufacturing and customer support. Our goal has always been straightforward: build electrical assemblies that perform reliably, meet technical requirements and are available when customers need them.
The certification strengthens that foundation. By integrating UL standards into every step of the production process, we ensure that quality and repeatability are built in from design to delivery. It also opens doors to new opportunities, allowing us to supply certified assemblies for large-scale infrastructure, data centers and industrial projects that require documented compliance.
Just as important, UL891 certification enhances our ability to manage quality across every stage of production—from design and sourcing to assembly and testing. Even when collaborating with trusted fabrication partners, ASG Power maintains oversight of all specifications, documentation and testing requirements to ensure every product meets the same consistent standard.
This achievement aligns with our larger mission: to combine technical capability with dependable delivery, giving customers access to switchboard solutions that meet the same standards as major electrical OEMs, while maintaining the flexibility and responsiveness of a focused manufacturer.
