Question: do i need afci or gfci?
Answer: The AFCI should not be confused with the GFCI. The AFCI (Arc Fault Circuit Interrupter) protects against fires caused by arcing faults. Arcing faults often occur in damaged or deteriorated wires and cords. ... The GFCI (Ground Fault Circuit Interrupter) is designed to protect people from severe or fatal electric shocks.
