What type of outlet often includes protective features against arcs caused by faulty wiring?

AFCI outlets, or Arc Fault Circuit Interrupters, are specifically designed to protect against arc faults that may occur due to faulty wiring or damaged electrical devices. An arc fault is an unintended, high-power discharge of electricity that can occur when there's a break or flaw in the wiring. This type of outlet detects the unique characteristics of an arc and interrupts the circuit, reducing the risk of electrical fires that such faults can cause.

The technology within AFCI outlets enables them to differentiate between normal electrical activity and potentially harmful arcs, allowing for immediate response to dangerous conditions. This feature makes AFCI outlets particularly important in providing an added layer of safety in living spaces, especially where the risk of electrified fabric or dust may occur.

In comparison, standard outlets lack any protective features for electrical faults, while GFCI outlets primarily protect against ground faults that might lead to electric shocks. USB outlets provide convenient power sources for devices but do not include any arc protection. Therefore, AFCI outlets are the most appropriate choice for protection against arc faults in residential and commercial wiring systems.
