Arc Fault Detection

What is an arc fault?

An arc fault occurs when a gap of air develops between two conductors. The result is a short, sudden release of energy that produces extremely high temperatures. These conditions have the potential to start a dangerous electrical fire. The sudden discharge of electricity may cause insulation, wood framing, and other nearby building materials to catch fire.

What are some of the causes of an arc fault?

An arc fault can be caused by a number of different things, including:

- Moisture, humidity, and condensation
- Overloaded circuits
- Dust
- Corrosion
- Faulty appliances
- Poor installation
- Old wiring
- Pest/rodent damage
- Excess physical stress or strain

What can I do to prevent arc faults?

An arc fault is more likely to occur when the home’s electrical wiring becomes worn or damaged over time. Ensuring that your electrical wiring is up-to-code is one of the most important things you can do to prevent an electrical fire.

Additionally, the National Electrical Code now requires the installation of arc fault circuit interrupters (AFCIs) in most residential living spaces. Combination AFCI circuit breakers are required on any circuit that supplies power to outlets and appliances in most living spaces, such as kitchens, bedrooms, dining rooms, and living rooms.
