In just seconds, undetected arc faults can break out into an electrical fire. Broken wires, loose connections, crushed cables and worn insulation can all cause hidden arc faults in electrical circuits. Arc Fault Detection Device’s (AFDD’s), also known as Arc Fault Circuit Interrupter, can help to isolate the faulty circuit as soon as the Arc fault is detected.
Arc faults can be difficult to see. They usually occur in hidden places, such as damaged cables, inside walls or a loose connection in a hidden junction box, or outlet sockets.
Arc Faults are one of the main causes of electrical fires. These fires are surprisingly common in older buildings.
How Arc Fault Fires Start
What can cause Arc Fault?
What is an Arc Fault Detection Device?
An AFDD is a circuit breaker that automatically cuts the electricity supply when it detects an arc fault in a circuit.
By cutting the electricity supply, AFDD’s help prevent arc faults from reaching temperatures where electrical fires can break out.
Where to use AFDDs Recommended by AS/NZS 3000:2018
Homes, dormitories, and other places with sleeping accommodation
Fire propagating structures
Museums, galleries that have irreplaceable goods
Day care centres, pre-schools, schools, retirement and nursing homes; areas where there are children, handicapped and elderly people
Large gathering places, like cinemas, universities, restaurants, underground stations, office complexes and shopping centres
Risk locations, this risk may be from what is stored there, such as a barn or wood working shops
Locations with combustible construction materials like wooden buildings
Escalated Risk
Power circuits (connected to socket outlets) have a higher risk of arc faults because of the following reasons:
- Arcing in extension boards
- Damaged cables due to being plugged in behind furniture
- Damaged extension leads from bending around corners or trapped under furniture
- Damage to plugged cables due to temperature variation, ultraviolet rays, vibrations, humidity, and rodents in outdoor environment.
