What is an Arc-Fault Circuit-Interrupter?
An arc-fault circuit-interrupter (AFCI) is designed to shut down a circuit once it detects an arcing situation on the circuit. This ingenious device seems to have a mind of its own. It can distinguish between a normal arc, like that of a switch turning on and off, a cord being unplugged, and an appliance contact shutting off, verses a loose contact that is arcing and is going to cause a problem. This remarkable device detects hidden wiring problems in your home that you may not even be aware of. How much is that worth to you?
Do I Need Arc-Fault Circuit-Interrupters in My Home?
Not only is it a good idea to install these breakers in your home for peace of mind, but the National Electric Code requires AFCI’s in the bedrooms of your home in new construction. Protecting the branch circuits that supply 125-volt power via 15 and 20-amp circuits is a must. Now that you know a little more about these protective devices, you may want to install them in your existing home as well. Remember, many people die each year in house fires and many are caused by faulty wiring. Don’t take the chance. Upgrade to better protection and sleep well tonight.
