This has elevated public and legislative consciousness regarding the need for robust protective devices.
From an economic perspective, ongoing construction and infrastructure development, particularly in residential and commercial building sectors, provides a sustained and expanding customer base for circuit protection devices. Moreover, the rising trend of smart homes and building automation systems creates demand for intelligent circuit breakers that can support energy management, remote monitoring, and enhanced efficiency. The integration of smart features into electrical infrastructure is a key trend in the UK, creating new opportunities for manufacturers who can offer products with advanced capabilities.
AFDDs – now mandatory in HRRBs, HMOs, student housing, and care homes; recommended elsewhere to reduce electrical fire risks.
RCBOs – encouraged for individual circuits in homes to prevent nuisance tripping.
Surge Protection – required where overvoltages could cause injury or major financial loss.
These updates make advanced RCBOs and RCBO/AFDD combos essential for compliance and a major market growth driver.
RCBOs are evolving with smart features such as real-time diagnostics, remote monitoring, and integration with building management systems. This shift improves safety, energy efficiency, and maintenance.
Example: Smart RCBO/AFDDs (e.g., Hager) can detect specific faults like EV charger issues and resolve them via software updates—no device removal required. This "fit-and-forget" capability reduces nuisance tripping and lowers maintenance costs.
However, IoT-enabled devices also introduce cybersecurity considerations, making secure design and updates critical.
The UK’s net-zero push is boosting demand for advanced RCBOs. Solar PV inverters and EV chargers generate DC fault currents that standard Type AC RCBOs may miss, creating safety risks. Regulations now recommend Type A and Type B RCBOs, driving a fast-growing market segment essential for grid stability, equipment protection, and occupant safety.
