What is the Difference Between GFCI and AFCI Circuit Breakers?

Square D circuit breakers designated as Arc Fault Circuit Interrupters (AFCI) are not the same as Ground Fault Circuit Interrupters. Square D breakers with AFCI protection are made to guard against accidental fires caused by current arcs. Ground Fault Circuit Interrupters are made to protect people from electrical shocks.

GCFI circuit breakers do this by monitoring the current which flows between the "hot" and neutral sections of a wall socket. If there is any imbalance in the current, the circuit is tripped to prevent electric shock. If you are using an electric appliance and you step into a puddle of water, for example, the current can transfer to you, altering the balance in the current between hot and neutral. A GFCI circuit breaker stops the flow of electricity the moment that altered balance is detected. Square D circuit breakers designated as AFCI are not inferior to GFCI circuit breakers, they simply protect the home in different ways.
