Permanent and Temporary PDU Installations
In today’s fast-paced commercial, industrial, and event environments, the safe and efficient distribution of electrical power is critical. Whether it’s a permanent installation for a manufacturing facility or a temporary setup for a construction site or festival, choosing the right Power Distribution Unit (PDU) or Electrical Distribution Board ensures reliability, compliance, and operational efficiency.
What is a Power Distribution Unit?
A PDU is a device that distributes electrical power from a single source to multiple outputs. Also known as a distribution board, panelboard or breaker panel, it’s a critical component of any electrical system. A successful distribution board installation helps you achieve a reliable and secure electrical setup for your business.
Key Functions:

How a Power Distribution Board / Unit Works
A distribution board is the central hub that splits incoming electrical power into multiple circuits, each protected by a fuse or circuit breaker. Housed in a durable enclosure, it safeguards against overcurrent and short circuits, often including additional devices like RCDs or GFCIs for shock protection. Its design allows easy maintenance, quick circuit identification, and can range from small residential units to large, complex systems for commercial and industrial use, ensuring safe and efficient power distribution throughout a building.
Choosing a Suitable Electricity Distribution Board / Unit
When selecting a PDU or distribution board, factor in the following:
- Load Capacity: Ensure the unit can handle peak demand
- Number of Outlets / Circuits: Match to the number and type of devices
- Voltage & Phase Requirements: Single-phase or three-phase compatibility
- Protection Features: Circuit breakers, RCDs (Residual Current Devices)
- Weatherproofing: IP-rated for outdoor or damp environments
- Compliance: Meets UK standards (BS EN 61439 for assemblies, BS 7671 wiring regulations)
Different Types of PDUs & Distribution Boards
- High Voltage (HV) Distribution Boards
Voltage Range: Typically above 1,000 volts AC
Usage: Found in large-scale industrial plants, power generation facilities, and high-demand manufacturing operations. - Low Voltage (LV) Distribution Boards
Voltage Range: Up to 1,000 volts AC
Usage: Most common in commercial buildings, factories, and residential settings. - Temporary Power Distribution Units
Designed for short-term or mobile projects, often low voltage but built for portability and weather resistance. - Intelligent / Metered PDUs
Equipped with digital monitoring systems to track power usage, detect faults, and enable remote management.
PDU Applications by Sector
- Industrial: High-load machinery, conveyor systems
- Commercial: Office equipment, lighting systems
- Events: Audio-visual equipment, catering setups
- Construction: Power tools, site lighting, welfare facilities

PDU Safety & Compliance Standards
Safety is non-negotiable in electrical distribution. In the UK, PDUs and distribution boards must adhere to:
- BS EN 61439: Low-voltage switchgear and controlgear assemblies
- BS 7671: Requirements for electrical installations (IET Wiring Regulations)
- HSE Guidance: Safe use of electricity at work
Regular inspection and testing under the Electricity at Work Regulations 1989 is essential to maintain compliance.
