    Why use small RCBO?
    Miniature RCBOs (Residual Current Circuit Breakers with Overcurrent Protection) offer a compelling solution for electrical installations due to the unique combination of RCD (Residual Current Device) and MCB (Miniature Circuit Breaker) functions in a single device.  RCBO's RCD components are specifically designed to detect earth leakage, preventing the risk of current flowing where it shouldn't and providing vital protection to individuals.
    In traditional residential installations, a combination of RCDs and MCBs are often used in consumer units to protect multiple circuits. However, this approach can lead to a situation where a ground fault on one circuit triggers the disconnection of an entire group of circuits, including those that are functioning normally. This practice violates the specific provisions outlined in the IET Wiring Regulations, 17th Edition, in particular Chapter 31 - Installation, Clause 314.1.
    Regulation 314.1 emphasizes the need to divide installations into circuits to achieve several key objectives, including avoiding hazards in the event of failure, facilitating safety inspection, testing and maintenance, taking into account hazards arising from faults in individual circuits, and reducing inaccuracies not caused by faults. Possibility of necessary RCD tripping.
    By integrating micro RCBOs into electrical installations, these devices are able to comply with the regulatory requirements outlined in the IET 17th Edition Wiring Regulations. They provide a more precise and targeted approach to circuit protection, ensuring that disconnection of a circuit is limited to the specific area affected by a fault, thereby increasing safety, minimizing disruption and simplifying maintenance and testing procedures. This makes micro RCBOs the first choice for modern electrical installations, complying with the principles of safety, efficiency and regulatory compliance.
