Reliable Power Distribution Panels, Built for Industrial Demands
At PDC Electric, we specialize in designing and building UL 508A panels that are built to handle the real-world demands of commercial and industrial environments. Our systems are engineered from scratch to deliver safe, consistent power where and when you need it.
Each panel we produce is part of a broader power strategy. We make sure your infrastructure is ready and rock solid, whether you’re feeding multiple machines, powering high-torque equipment, or managing loads across complex automation systems.
As a certified UL 508A panel shop, we deliver:
- Custom power distribution panels designed for your exact voltage, load, and layout requirements
- In-house fabrication and testing, backed by UL’s rigorous safety standards
- Panels built for seamless integration with VFDs, PLCs, and industrial machinery
- Field-proven reliability in manufacturing plants, warehouses, and robotics systems
From new builds to retrofits, we design power distribution systems that minimize downtime, simplify maintenance, and scale with your operation.

What is a UL 508A Panel?
A UL 508A control panel is an industrial electrical control panel that has been certified by UL Solutions to meet strict safety and construction standards for the US markets. These standards make sure that the panel can safely house electrical components used to operate and control machinery, automation systems, and heavy equipment in a wide range of industrial environments.
To carry the UL 508A label, a panel must be built in a UL 508A panel shop, which is a facility authorized by UL and staffed with trained, certified personnel who follow rigorous documentation, wiring, and inspection protocols. This UL listing is not just a compliance box to check — it’s a visible sign of safety, quality, and reliability. Inspectors, engineers, and procurement teams recognize UL 508A certification as a major trust factor when choosing a panel shop.
What Does a UL 508A Panel Do?
At its core, a UL 508A panel acts as the nerve center of an industrial electrical system. It controls and distributes power to components like:
- Motors and Motor Starters
- VFDs (Variable Frequency Drives)
- Robotic arms and automation cells
- Pneumatic and hydraulic systems
- PLC-based controls and sensor networks
- Overhead cranes, hoists, conveyors, and more
These panels are engineered to match the specific equipment and operational requirements of each facility, with the right enclosure size, power rating, safety features, and control interface.
Custom UL 508A Control Panels Built In-House
Design & Engineering
We collaborate with your team or equipment supplier to engineer a panel that matches your voltage, amperage, and control logic requirements.
Custom Fabrication
Every panel is built in-house at our UL-certified shop, careful attention to layout, NEC-compliant labeling, and safety protocols.
Testing & Verification
Before leaving our shop, all panels go through functional testing, point-to-point checks, and compliance review.
Installation & Field Integration
We offer full installation services within Washington and ship control panels nationwide as well.
Why UL 508A Certification Matters for Your Control Panels
Control panels that aren’t UL-listed can fail inspections, cause delays, or even introduce safety risks. Choosing a UL 508A panel shop like PDC Electric means your system is built to meet OSHA, NEC, and NFPA standards, increasing your chance of passing inspections by the Authority Having Jurisdiction (AHJ). It also helps protect operators, equipment, and property from electrical hazards. When your project needs to reflect code compliance and professionalism, UL 508A certification makes a difference your clients can see.
