Electrical Consumer Units

  1. Main Switch: This switch allows you to shut off the electricity supply to the entire premises in case of emergencies or maintenance tasks.

  2. Residual Current Devices (RCDs): RCDs are safety devices that help protect against electric shocks and fatal accidents. They quickly detect any imbalance in current flow caused by a fault or leakage and disconnect the affected circuit.

  3. Circuit Breakers: These devices protect individual circuits from overloading or short circuits. Circuit breakers automatically trip and shut off the power flow when they detect an excessive current, preventing damage to wiring and appliances.

  4. MCBs/RCBOs: MCBs (Miniature Circuit Breakers) or RCBOs (Residual Current Breaker with Overload Protection) are individual circuit breakers that control and protect specific electrical circuits. They can be reset manually after tripping due to an overload or fault.

  5. Busbars: Busbars are metal bars inside the consumer unit that distribute electricity to different circuits. They provide a central connection point for outgoing and incoming cables.

  6. Neutral and Earth Terminals: These terminals provide a safe path for electric currents to return to their source and for grounding excess electricity, respectively, thus ensuring the proper functioning of the electrical system.

  7. Labels and Clear Markings: Electrical consumer units typically have labels and clear markings indicating the circuits they control, making it easier to identify and isolate specific circuits during electrical work or troubleshooting.

Please note that electrical consumer units must be installed and maintained by a qualified electrician to ensure compliance with safety regulations. It's important to regularly inspect and test your consumer unit to ensure its proper functioning and safety.
