What's The Difference Between GFCI And AFCI Outlets?

Ground Fault Circuit Interrupter (GFCI) outlets are most common in rooms with water sources, like bathrooms and kitchens, and are designed to protect people from severe electric shocks.

A ground fault is an abnormal and unintentional electrical path that directs current to the ground. Ground faults occur when an electrical current escapes a home’s insulated wires as a result of damaged wiring. A GFCI outlet detects the flow of a home’s electrical currents through its wires and senses the presence of ground faults. If a ground fault is found, the GFCI outlet shuts off the flow of electricity to prevent a person from receiving a fatal shock.

Arc Fault Circuit Interrupter (AFCI) outlets are designed to protect a home from fires caused by arcing faults. Arcing faults occur when loose wire connections or corroded wires lead to sparks or arcing, which can then lead to electrical fires. AFCIs detect these arcs on the circuit and respond by cutting off electricity to the circuit.

When Should I Replace My Electrical Outlets & Switches?

• Sparks or Smoke — If an outlet sparks or smokes when an appliance is plugged into it, this is a clear sign that something is wrong. There is a good chance the outlet was exposed to water or there was a short circuit. Sparking outlets can even cause house fires, so it’s best to call a licensed electrician ASAP.
• Cracked Outlet Plates — When an outlet’s cover plates become cracked, some of its wires can become exposed, which presents a shock risk and fire hazard. When this happens, do not use the outlet until it can be replaced.
• Discolored Outlets — Signs of discoloration can indicate overheating and a need for the outlet to be replaced.

If your outlets and switches display any of these signs, call Charlton & Hill ASAP. You shouldn’t try to repair or replace them without the help of a licensed electrician due to the potential safety hazards. The pros at Charlton & Hill in Lethbridge will be able to assess your outlet’s condition and determine the best course of action.
