An AFDD is a device that is installed in your consumer unit to protect against arc faults. It does this by monitoring the waveform of electricity being used to detect unusual signatures that would signify an arc. When an arc is detected, power to the circuit is cut off and the threat of fire is minimised. They are specifically designed to be more sensitive to arcs than regular circuit protection devices.

The smart way to detect arc faults in your circuit. With the amendment 2 of the 18th Edition it is now recommended for AFDDs to be installed for circuits supplying socket outlets in 4 areas;

• High Risk Residential Buildings (18m or 6 Storeys +) 
• Houses of Multiple Occupancy (HMO)
• Purpose Built Student Accommodation
• Care Homes

What can an AFDD Detect?

A series arc fault

• Is where the arc happens between two parts of the same conductor, such as a broken line conductor or a poorly terminated line conductor. 

A parallel arc fault

• Is where the arc occurs between the line conductor and either the neutral or earth conductors. If an arc fault occurs between line and earth there is quite a high likelihood that the RCD part of the AFDD will also operate. 

Over Voltage Detection

• This may indicate that the property has had a surge in voltage, if this continues you would need to contact the Electricity provider for your property
