Understanding Distribution Panels: Components, Types, and Applications
A distribution panel (also called a distribution board, breaker panel, or electrical panel) is a key component in any electrical system. It serves as the central hub that distributes electrical power from a main source to multiple circuits throughout a building or facility. Raise and Lower (Pty) Ltd has a long history and experience in this industry.
Definition:
A distribution panel is an enclosure that houses protective devices like circuit breakers, fuses, and sometimes relays. Its job is to divide incoming electrical power into separate circuits and provide protection through breakers that trip during overcurrent or short circuits.
We are able to assist in any of the key components as listed below as separate entities or even as a complete Distribution Panel ( manufacturing to the customers specifications)
Key Components of a Distribution Panel
| Component | Description |
|---|---|
| Main Breaker | Controls power to the entire panel; can shut off all circuits. |
| Busbars | Conductive bars that distribute electricity to breakers. |
| Circuit Breakers | Protect individual circuits by tripping when overloaded. |
| Neutral Bar | Collects the neutral wires from each circuit. |
| Earth (Ground) Bar | Connects to grounding wires for safety. |
| Enclosure | The metal or plastic box that contains all the components. |
Types of Distribution Panels
| Type | Use Case |
|---|---|
| Main Distribution Board (MDB) | Central panel in large buildings or commercial setups. |
| Sub Distribution Board (SDB) | Feeds from the MDB; used to distribute power to specific floors or sections. |
| Final Distribution Board (FDB) | Used for final load circuits (lighting, outlets, etc.). |
| Motor Control Panel | For powering and controlling electric motors. |
| Lighting Distribution Board | Specifically for managing lighting circuits. |
Applications
- Commercial buildings - For lighting, HVAC, server rooms
- Industrial facilities - Heavy-duty panels for machines, motors, welding equipment
- Construction sites - Temporary panels for tools and lighting
Safety & Compliance
- Must comply with standards SANS9000\SANS90001
- Proper earthing/grounding is critical
- Use lockable enclosures for security and safety
Custom Fabrication
In steel fabrication,
distribution panels often require custom enclosures, especially for:
- Outdoor use (IP65, weatherproofing)
- Corrosive environments (stainless steel or powder-coated steel)
- Compact spaces or integrated machinery panels
