Frequently asked questions

A consumer unit is an enclosure that houses electrical protection devices such as circuit breakers (MCBs), residual current devices (RCDs), and sometimes surge protection devices (SPDs). It serves as the main point of distribution and protection for electrical circuits within a building.

Consumer units play a crucial role in electrical safety by housing protective devices that monitor and control the flow of electricity. They protect against overcurrents, earth faults, and surges, thereby reducing the risk of electric shock, fire hazards, and damage to electrical equipment.

Components commonly found in consumer units include:

  • Miniature Circuit Breakers (MCBs): Protect individual circuits from overcurrents.
  • Residual Current Devices (RCDs): Detect earth leakage currents to prevent electric shocks.
  • Residual Current Circuit Breakers with Overcurrent protection (RCBOs): Combine the functions of MCBs and RCDs in a single unit.
  • Main Switch: Provides a means of isolating the entire consumer unit from the mains supply.
  • Surge Protection Devices (SPDs): Protect against transient voltage surges.
  • Busbars: Distribute the electrical supply from the incoming terminals to the protective devices and outgoing circuits.

Consumer units vary based on their design, size, and the type of protective devices installed. Common types include:

  • Metal Clad Consumer Units: Sturdy units suitable for industrial and commercial applications.
  • Plastic Consumer Units: Common in residential settings due to cost-effectiveness and ease of installation.
  • High Integrity Consumer Units: Include additional features such as dual RCDs for enhanced protection in domestic installations.

If a circuit breaker (MCB) in the consumer unit trips frequently, it may indicate an overload, short circuit, or fault in the circuit. It’s important to identify and rectify the cause to prevent damage and ensure electrical safety. Consulting with a qualified electrician is recommended.
