What Is a Consumer Unit?
A consumer unit is the main electrical control panel in a property, responsible for distributing electricity to individual circuits while providing essential protection against faults. It acts as the hub of the electrical system, ensuring safe and reliable power throughout the property.
Modern consumer units are equipped with advanced safety devices, including circuit breakers, Residual Current Devices (RCDs), and Residual Current Breakers with Overcurrent protection (RCBOs). These features automatically disconnect power when faults occur, helping to reduce the risk of electric shock, fire, and damage to appliances.
