Why do Older Homes Need Arc-fault Circuit Interrupters?

Older homes are particularly vulnerable to electrical hazards because their wiring systems may have deteriorated over time. Arc-fault circuit interrupters (AFCIs) are essential for these properties because they detect dangerous electrical arcing—essentially sparks within your wiring—that standard circuit breakers are simply not designed to catch.

In older homes, arc faults often stem from several common issues that we frequently encounter:

• Aging or Cracked Insulation: Over decades, the protective coating on wires can become brittle, pinched by staples, or damaged by pests.
• Corroded Terminals: Connections in older systems can corrode, especially in humid environments, leading to unstable electrical flow.
• Loose Connections: Years of vibration or previous remodeling work can loosen wires at outlets, switches, or inside junction boxes.
• Frayed Cords: Daily wear and tear on antique lamps or older appliances can lead to frayed electrical cords.

When an arc occurs, it can reach temperatures of up to 10,000°F, which is hot enough to ignite wood or insulation inside your walls. While standard breakers protect against overloads and short circuits, an AFCI monitors the electrical waveform for the unique signature of a hazardous arc and shuts off power instantly to prevent a fire from starting.

We prioritize your safety by ensuring these devices are installed directly on the Electrical Service Conductors within your panel. Whether you are performing a renovation or simply looking to modernize your protection, our fully trained technicians provide code-compliant installations backed by a 100% satisfaction guarantee.

All work meets or exceeds electrical codes and industry standards. Licensed electricians handle all work.
