Distribution Boards

A distribution board, also known as a distribution panel or panel board, is one of the most important components of an electrical supply system. The board's primary function is to take the electricity from the main supply and distribute it safely to individual circuits throughout a building or property.

All buildings will have at least one distribution board, which is typically located where the main electrical feed enters the structure. The size and capacity of the panel board depend entirely on the amount of electricity being supplied and the number of individual circuits in a system.

RS Philippines has a great selection of high-quality distribution boards suitable for both single and 3-phase applications at competitive prices. Our range of panel boards is supplied by industry-leading brands, including Schneider Electric, Siemens, ABB, Eaton, and Contactum.

How Does a Distribution Board Work?

The functions of a distribution board include:

Power Reception: The electrical distribution board receives electricity from the main incoming supply or transformer.
Circuit Distribution: It divides the electrical load into multiple subsidiary circuits, directing power to lights, outlets, machines, and appliances.
Protection Mechanisms: Circuit breakers and fuses within the power distribution board automatically interrupt current flow during overloads or short circuits, protecting both equipment and users.
Control and Monitoring: Modern distribution panel boards often include control switches, meters, and indicators for monitoring voltage, current, and power usage.

Key Benefits of Using a Panel Board

Centralized Power Control: A main panel board provides a single point for managing and isolating different electrical circuits, making it easier to monitor energy consumption.
Enhanced Safety: Equipped with circuit breakers and protective components, an electrical panel board prevents overloads, electrical fires, and equipment damage.
Organized Wiring: A distribution panel board simplifies circuit organization, keeping wiring neat and traceable for easier troubleshooting and modifications.
Ease of Maintenance: With clearly labeled circuits and accessible breakers, maintenance and system upgrades can be performed quickly and safely.
Scalability: Many modern power distribution boards allow for expansion, enabling additional circuits or higher capacity as building demands increase.

Applications of Distribution Boards

Distribution boards are indispensable across multiple sectors, including:

Industrial Machines: Distribution boards power heavy-duty equipment, including motors, conveyors, pumps, and production lines. They ensure precise circuit control, enabling operators to isolate, protect, and manage electrical loads safely, minimizing downtime and equipment damage.
Electrical Panels: In larger installations, distribution boards allow for organized branching of circuits, making it easier to maintain, troubleshoot, or expand the electrical system without affecting the entire facility.
HVAC Systems: Heating, ventilation, and air conditioning (HVAC) systems rely on distribution boards to manage fans, compressors, and motors. The boards regulate power to these components, ensuring smooth operation, protecting against overloads, and allowing for energy-efficient management of large-scale cooling and heating systems.
Generators and Power Systems: For facilities with backup power solutions, distribution boards integrate changeover switches and circuit protection, which enable seamless transition between mains and generator power during outages.
Automation Systems: Distribution boards support PLCs (programmable logic controllers), sensors, and other automated machinery, ensuring reliable operation while safeguarding against short circuits, voltage fluctuations, or unexpected faults.

How to Choose the Right Distribution Board

Before buying a distribution board for your system, consider the following factors:

Determine Load Requirements: Calculate the total electrical load of your facility or system, including all current and potential future equipment. This ensures the distribution board can handle peak loads without overheating or tripping frequently.
Select Appropriate Amperage: Choose the correct amperage rating to prevent overloading. Underrated boards can cause frequent tripping or even pose fire hazards, while oversized boards may lead to unnecessary costs and inefficient space usage.
Consider Phase Type: Distribution boards come in different phases, from single-phase to 3-phase and 4-phase. Make sure to choose the one that suits your application.
Check Compliance: Ensure the distribution board complies with Philippine electrical codes and international safety standards like IEC or UL certifications. Compliance guarantees that the board meets strict safety and performance benchmarks.
Material and Build Quality: Look for durable enclosures made from corrosion-resistant metals or powder-coated steel. High-quality materials extend the lifespan of the board, prevent rusting, and maintain safety over time.

Panel Board Price Range in the Philippines

The panel board price in the Philippines varies depending on factors such as capacity, configuration, material, and brand reputation. If you want an idea of how much you need for a panel board, check out this guide on the price range for the panel boards at RS Philippines:

Budget Options: Designed for residential or small-scale applications, basic single-phase panel boards are available starting from approximately PHP 800. These units are designed for light loads and provide essential circuit protection for small homes or office spaces. Despite their affordable price, they still meet safety standards and are suitable for everyday electrical needs.
Mid-Range Models: Standard panel boards for medium-sized homes, commercial offices, or light industrial setups typically range between PHP 4,000 and PHP 10,000. These mid-range models often come with higher amperage ratings, additional circuit slots, and more durable enclosures. They strike a balance between functionality and cost, making them a popular choice for businesses and expanding households.
High-End Units: Premium or industrial-grade panel boards can cost up to PHP 25,000 or more, depending on capacity and advanced features. High-end units are ideal for factories, large commercial buildings, or facilities with heavy machinery. They often include advanced safety features, corrosion-resistant enclosures, surge protection, and compatibility with automation systems.
