Panelboards
High-performance power distribution, lighting, and heat-trace panelboards. Engineered for safety and reliability in any environment.
What is a Panelboard?
A panelboard is a single-panel or group of panel units designed for assembly in the form of a single panel.It includes buses and overcurrent devices (circuit breakers or fuses) with or without switches for the control of light, heat, or power circuits.It is designed to be placed in a cabinet or cutout box placed in or against a wall.
Power vs. Lighting Panelboards
| Feature / Característica | Lighting & Appliance Panels | Power Distribution Panels |
| Primary Use / Uso | Branch circuits (lights, outlets). | Heavy machinery & sub-feeds. |
| Amperage / Amperaje | Typically 100A to 600A. | High capacity 400A to 1200A. |
| Breaker Type / Tipo | Plug-on or Bolt-on (1-pole, 2-pole). | Large Frame Bolt-on (up to 3000A). |
| Standard / Norma | UL 67 | UL 67 / NEMA PB1 |
Technical Specification
Voltage: 120V, 208V, 240V, 277V, 480V, 600V.
Interrupting Capacity (AIC): 10k, 22k, 42k, 65k, 100k, 200k.
Certification: UL 67 Listed.
Busbar Technology: The "Gold Standard"
We offer two primary busbar materials. Copper (Silver or Tin-Plated) is our recommendation for industrial use due to its superior conductivity and lower thermal expansion. Aluminum is available as a cost-effective, lightweight alternative for commercial applications.
NEMA Enclosure Selection
NEMA 1 (General Purpose): Clean indoor environments (Electrical rooms).
NEMA 3R (Weatherproof): Outdoor use; protects against rain and ice formation.
NEMA 12 (Industrial Dust-Tight): Protects against circulating dust, lint, and dripping non-corrosive liquids. Essential for manufacturing floors.
NEMA 4X (Corrosion Resistant): Made of 304 or 316 Stainless Steel. The only choice for Wastewater, Food Processing, or Coastal region
Key Features & Advanced Options
- Integrated Surge Protection (SPD): Protecting the entire panel from external voltage spikes (lightning) or internal switching surges.
- Digital Power Metering: Real-time monitoring of Volts, Amps, and Power Quality (THD) via Modbus or Ethernet.
- Sub-Feed & Feed-Through Lugs: Allows for easy expansion and connection to additional downstream panels.
- 200% Rated Neutrals: Crucial for modern facilities with high non-linear loads (VFDs, Computers) to prevent neutral overheating.
Top Manufacturers:
Eaton, Square D, Siemens, ABB/GE We distribute and customize the world’s most trusted brands, ensuring your facility is powered by gold-standard components.
Why Choose ADP Panelboards?
We don't just "move boxes." We take a standard Eaton or Siemens panel and customize the enclosure and internal configuration to meet your specific site constraints, providing a Plug-and-Play solution.
We specialize in Fast-Track Customization. While the "Big 4" manufacturers may have 20-week lead times, ADP can assemble and certify a UL-listed panel in a fraction of that time, customized to your exact circuit and footprint requirements.
