Long lead times and rising equipment costs have become major challenges across the electrical industry. Many panel shops and OEMs are waiting months — sometimes more than a year — for complete switchboards or panelboards from major manufacturers. For fast‑moving sectors like data centers, utilities, and commercial construction, those delays can stall projects and drive up costs. LS Electric offers a smarter, more flexible alternative.

The LS Electric UL Assembler Program gives qualified panel shops the ability to build UL‑listed switchboards and panelboards in‑house, using LS Electric’s certified components. This approach delivers faster turnaround, lower costs, and more control — a major advantage in today’s demanding project environment.

What Is the UL Assembler Program?

The UL Assembler Program is LS Electric’s structured pathway for panel shops to manufacture UL 891 switchboards and UL 67 panelboards using LS Electric’s certified system. Instead of purchasing a finished assembly, shops use LS Electric’s:

UL 891 switchboard architecture
UL 67 panelboard architecture
UL489 molded‑case circuit breakers
Certified interiors, bus straps, and accessories
Documentation and guidelines required for UL compliance

This gives assemblers the freedom to build equipment that meets UL standards while controlling their own timelines, layouts, and budgets.

The Technology Behind the Program: The Susol UL891 / UL67 System

At the core of the program is LS Electric’s Susol UL891 Switchboard Solution, which is dual‑certified for both UL 891 and UL 67 applications. According to LS Electric’s published specifications, the system includes:

UL67/UL891 certified interiors
UL489 MCCBs
Main bus options from 1200A to 6000A
Branch breakers up to 1200A
100kA @ 480V interrupting rating
Five interior types
Three bus strap configurations
Direct branch‑bus connection for simplified layouts

This modular, flexible system allows panel shops to design boards that match their application needs — without being locked into rigid OEM configurations.

Why Panel Shops Are Turning to the UL Assembler Program

1. Faster Lead Times

Instead of waiting months or years for a complete switchboard, assemblers can build UL‑listed equipment on their own schedule. This is especially valuable for industries where delays can be costly.

2. Lower Total Cost

By building in‑house, panel shops avoid the markup of finished assemblies. LS Electric’s component pricing is often more competitive than legacy OEMs, creating immediate savings.

3. Full UL Compliance Without the Complexity

LS Electric provides the UL files, documentation, and guidelines. Assemblers get the freedom to build — without navigating certification alone.

4. Design Flexibility

Modular interiors, a wide MCCB range, and multiple bus configurations allow shops to tailor equipment to each project.

5. A Scalable, Repeatable Platform

Once a shop adopts the LS Electric system, they can standardize on it — improving efficiency and consistency across future builds.
