What are the components of a consumer unit?

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.
