When you hear alight switch or outlet buzzingor hissing, you are hearing arcing as it happens.
What Causes an Arc Fault
An arc fault is essentially triggered by stressed electrical wiring or devices.
This can include equipment or wiring that is damaged or overheated.

When current flows through an unwanted path, an arc fault can occur.
This process generates intense heat, which can ignite nearby materials such as wood framing or insulation.
How is an Arc Fault Detected?
Arc Fault vs. Short Circuit vs. ## What Is Arc-Fault Protection?
A detection gear senses the electrical arc and breaks the circuit to prevent an electrical fire.
Arc-fault protection devices keep people safe and are essential for fire safety.
Not all communities comply with the NEC, however, so checklocal authoritiesfor requirements regarding AFCI protection.
Why Do You Need Arc Fault Circuit Interrupters (AFCIs)?
Electrical fires can be a silent killer in the home and do extensive damage.
How Does an AFCI Work?
Advanced electronic technology is used to detect “normal” and “dangerous” arcing conditions in the circuit.
Two types of safety outlets can protect you and your home.
GFCI protection will prevent electrical shocks by cutting off the electric current when it travels to the ground unintentionally.
you might attempt to troubleshoot an arc fault yourself.
First, unplug everything in the circuit.
Electricity will always seek a path to ground.
When this unintentional path is a person’s body it may result in severe shock or even be fatal.
Several different conditions can cause an arc fault breaker to trip.
They include poor connections, overloaded circuits, dampness or mold, and appliances or devices that are incompatible.
