AFDDs, or Arc Fault Detection Devices, are the latest addition to the types of circuit protection used within electrical installations. They are designed to prevent fires caused by electrical arcs, which can be generated if cables or connections become damaged. In this video, we explore how AFFDs work and where they are used within UK electrical installations. This video is part of a series covering all types of circuit protection and can be used as part of your CPD continuing professional devel

AFDD(Arc Fault Detection Device) AFDD stands for Arc Fault Detection Device. It is a safety device used to detect and protect against electrical arcs, which can cause fires. An AFDD monitors the electrical system for abnormal arcing conditions and quickly interrupts the circuit if an arc fault is detected. Arc faults can occur due to damaged or deteriorating wiring, loose connections, or other electrical faults. AFDDs are designed to detect the unique characteristics of arc faults and distinguis
