AFDD RCBO combines arc fault detection (series and parallel) caused by loose connections, incorrect wiring or rodent bites with detecting earth fault currents, overload or short circuit currents.

AFDD uses microprocessors to detect changes in the electrical waveform which could result in arcing, overheating and causing a fire while RCBO reduces the number of injuries caused by electric shock from earth leakage or over-current.

From March 2022, in accordance with the BS7671 18th Edition AMD2, AFDDs became a requirement in Higher Risk Residential Buildings, Houses in Multiple Occupation, Purpose-built Student Accommodations, and Care Homes. They should be installed at the beginning point of any single-phase AC final circuits that provide power to socket-outlets with a rated current that does not exceed 32A.
