GFCI vs AFCI What Every Homeowner Should Know

Introduction

If you’ve ever looked at your home’s electrical outlets and noticed ones with buttons labeled “Test” and “Reset,” you’ve seen a type of safety device called a GFCI. And if you’ve had an inspection done recently, you’ve probably heard your electrician mention AFCI protection as well.

Both serve critical roles in modern electrical safety—but they’re not the same thing. At Lynn Electric, we regularly help Kansas City homeowners understand and upgrade their electrical systems with the right type of protection. Here’s what you should know about GFCI vs. AFCI outlets—how they work, where they’re used, and why they matter.

What is a GFCI Outlet?

GFCI stands for Ground Fault Circuit Interrupter.
Its main job is to protect people from electric shock.

If the GFCI senses even a tiny difference in electrical current between the “hot” and “neutral” wires (often caused by water or moisture contact), it instantly cuts power—usually within a fraction of a second.

Common installation areas:

• Bathrooms
• Kitchens
• Garages
• Outdoor outlets
• Basements

Because these locations have a higher risk of moisture exposure, GFCI outlets are required by modern building codes in nearly every new or remodeled home.

What is an AFCI Outlet?

AFCI stands for Arc Fault Circuit Interrupter, and its job is to protect your home from electrical fires.

An “arc fault” occurs when damaged wires, loose connections, or worn insulation cause electricity to jump (or “arc”) between conductors. These arcs generate intense heat and can easily start a fire behind your walls—often without any visible signs.

Common installation areas:

• Bedrooms
• Living rooms
• Dens and hallways
• Home offices

AFCI outlets or breakers detect these dangerous arcs and automatically shut down the circuit before a fire can start.

In short:

• GFCI = Shock protection
• AFCI = Fire protection

Many modern outlets and breakers now combine both functions, providing comprehensive safety coverage for your entire home.

When Should You Upgrade?

If your home was built before 2008, chances are your electrical system doesn’t have full AFCI coverage. Even GFCIs may only be installed in limited areas.

Upgrading provides two benefits:

1. Improved safety and code compliance for resale or remodeling
2. Peace of mind knowing your family and property are protected from unseen hazards

Why Professional Installation Matters

While GFCI and AFCI outlets may look simple, installation mistakes can make them ineffective—or worse, dangerous.

Common DIY errors include:

• Miswiring “line” and “load” terminals
• Daisy-chaining multiple GFCIs incorrectly
• Failing to identify shared neutrals on AFCI circuits

At Lynn Electric, our licensed electricians ensure every outlet is properly installed, tested, and compliant with National Electrical Code (NEC) requirements.
