Why do I need Arc Fault protection as well?

Water is not the only think that presents a danger to the electrical lines in a home. Aging appliances and wiring can also cause a problem known as “arcing.” This phenomenon can cause overheated wires or actual electrical discharges and lead to the start of a fire. Normal arcing is common in electrical circuits such as when a switch is thrown or an appliance is started. An Arc Fault Circuit Interrupter (AFCI) selectively monitors the current flow and can discriminate between this normal arcing and unwanted, erratic arcing conditions that can cause a fire.
