AFCI vs. GFCI: What's the Difference?

This is the most common question homeowners have, and the answer is critical. AFCI and GFCI devices look similar, but they protect you from two completely different dangers. You need both.   

A GFCI (Ground Fault Circuit Interrupter) protects PEOPLE from SHOCK. This is the device with the "Test" and "Reset" buttons. It monitors the flow of electricity in and out of the circuit. If it detects even a tiny imbalance, meaning electricity is escaping and "leaking" to the ground (for example, through your body or a puddle of water), it trips in a fraction of a second, cutting off the power and preventing electrocution. This is why they are required in all wet locations.   

An AFCI (Arc Fault Circuit Interrupter) protects the HOUSE from FIRE. An "arc fault" is an unintentional spark, often caused by a frayed lamp cord, a nail driven through a wire, or a loose connection. These tiny sparks generate intense heat and are a leading cause of electrical fires. An AFCI device is designed to "listen" for the unique electrical signature of a dangerous arc and will trip to cut off power before a fire can start. This is why modern codes require them in most living areas, like bedrooms and living rooms.   

The Danger of a "Simple" Outlet Swap

Many homeowners with older properties see a two-prong outlet and think they can perform a simple DIY swap for a modern, three-prong outlet. This is a common and dangerous mistake.

That third hole in a modern outlet is the grounding connection. In an older home, the electrical box may not have a ground wire to connect to. Simply installing a three-prong outlet anyway creates the illusion of safety. You can plug in a three-prong cord, but the device is not grounded, and you have zero shock protection.

There are only two correct, code-compliant ways to fix this. The first is to run a new, grounded wire from the main panel, which is often part of a larger rewiring project. The second, more practical solution, is to install a GFCI outlet in that location. A GFCI is permitted to be installed on an ungrounded circuit because its own internal sensor will still protect you from shock, even without a ground wire.   

This project becomes even more dangerous in Bradenton homes with aluminum wiring. You cannot connect aluminum wires to a standard (copper-rated) outlet or switch. This creates a fire hazard. Special CO/ALR-rated devices must be used. What seems like a simple swap has serious safety implications that are best left to a professional.
