What are the differences between cafci and gfci and how do they impact electrical safety in a residential setting?

Cafci and gfci are both types of electrical safety devices, but they serve different purposes. A cafci, or combination arc fault circuit interrupter, protects against electrical fires caused by arcing faults in the wiring. A gfci, or ground fault circuit interrupter, protects against electric shock by monitoring the flow of current and shutting off power if a ground fault is detected. Both devices are important for electrical safety in a residential setting, as they help prevent fires and electrocution.
