Switchboards and panelboards play a critical role in distributing electrical power safely and efficiently throughout industrial facilities. These control panels are designed to manage high electrical loads, protect circuits, and support smooth operations in demanding environments.
What Is a Switchboard?
A switchboard is a large-scale power distribution unit that manages and directs electricity from a single source to various circuits or systems. Switchboards are typically rated for high amperage (up to 4,000 AMPS or more) and often built to UL 891 standards.
Key Features:
- Handles high power capacity
- Contains disconnects, fuses, circuit breakers
- Ideal for heavy-duty industrial applications
What Is a Panelboard?
A panelboard is a smaller electrical distribution unit that distributes power to branch circuits while providing circuit protection. Panelboards are generally used for lighter electrical loads compared to switchboards.
Key Features:
- Compact design
- Houses breakers for individual loads
- Used for lighting, small machinery, and branch circuits
Differences Between Switchboards and Panelboards
| Feature | Switchboard | Panelboard |
|---|---|---|
| Amperage Capacity | Up to 4,000+ AMPS | Up to ~1,200 AMPS |
| Application | Industrial power distribution | Building-level distribution |
| Standard Compliance | UL 891 | UL 67, UL 50 |
| Accessibility | Front and rear (often) | Front only (typically) |
Applications Across Industries
- Manufacturing Facilities – Centralized power control and load balancing
- Oil & Gas Plants – Distribution of high-voltage power in hazardous environments
- Data Centers – Reliable energy distribution for critical systems
- Hospitals – Uninterrupted power for life-safety systems
