BEAMA Guide to Arc Fault mitigation in low-voltage assemblies
BEAMA has published a new guide on arc fault mitigation in low-voltage assemblies. The guide identifies possible causes of internal arcing faults within low-voltage assemblies, outlines the measures that can be taken to reduce the likelihood of an arcing fault and/or its consequences, and assist the specifier in determining the most appropriate solution for their application.

BEAMA Fact sheet: An introduction to AFDDs
Modern technology within AFDDs now makes it possible to detect & disconnect dangerous arcs and enhance protection standards for people and property. Arc fault detection devices (AFDDs) disconnect the electricity supply when the presence of dangerous electrical arcs is detected, thus preventing the outbreak of fire.

BEAMA Fact sheet: What is an arc fault
An arcing fault is an unintentional arcing condition in a circuit. Arcing creates high intensity heating at the point of the arc resulting in burning particles that can over time ignite surrounding material. Repeated arcing can create carbon paths that are the foundation for continued arcing, generating even higher temperatures. The temperatures of these arcs can exceed 6000°C.
