Surge Protection, GFCIs, and AFCIs: The Safety Devices Every Home Should Have

Ground-Fault Circuit Interrupters (GFCIs)

GFCIs are available as receptacles and circuit breakers. These devices are designed to protect against electric shocks in areas where electricity and water may come into contact. Electricians in Boulder, CO often recommend Ground-Fault Circuit Interrupters in the kitchen, bathroom, garage, basement, and outdoor spaces, maintaining safe living spaces.

A GFCI monitors the flow of electricity continuously, comparing the current on the live wire to the neutral wire. If the device detects an imbalance as small as 4-6 milliamperes, it assumes current is escaping through an unintended path, such as water or a person, and instantly shuts off the power. While an upgrade may require electrical wiring and upgrades, GFCIs are a worthwhile investment towards maintaining safety.

Arc-Fault Circuit Interrupters (AFCIs)

Just like GFCIs, Arc-Fault Circuit Interrupters (AFCIs) are available as circuit breakers and receptacles. Electricians often install AFCIs in electrical fire-prone buildings, ensuring safety year-round. Research shows that nearly 50% of residential electrical fires can be prevented by investing in AFCI protection. Gone are the days when arc faults posed serious fire hazards and costly property damage.

An arc fault is a dangerous, unintended spark that occurs within loose or damaged electrical wiring, faulty appliances, or frayed cords. While these arcs may not raise concerns initially, they generate intense heat that can ignite nearby materials. An AFCI detects the unique “signature” of these hazardous arcs and rapidly cuts power before a fire can start. Electrical service providers can install an AFCI in areas with long runs or wiring and appliances, including dining rooms, living rooms, closets, and hallways.

Surge Protection Devices (SPDs)

Power surges can happen unexpectedly, causing severe property damage and premature appliance replacements. This is particularly true in areas that frequently experience adverse weather. Although surges are temporary voltage spikes, they can cause devastating damage within seconds.

SPDs are usually integrated as a whole-house unit at the main panel, diverting excess voltage to the ground and preventing it from reaching sensitive devices. Besides the elements, surges can be caused by large appliances cycling on and off or power grid switching. These devices work in tandem with point-of-use surge strips for critical electronics.

Why Hire a Licensed Electrical Service for Safety?

Whether it is a whole-house surge protector, a GFCI, or an AFCI unit, hiring a professional is crucial to ensure they handle complex systems and accurately diagnose issues before they escalate into hazardous situations. Our highly trained technicians follow national and local electrical codes, which are designed to prevent shocks, fires, and system failures, avoiding fines and ensuring safety.

Additionally, proper installation, grounding, and wiring by a professional technician dramatically reduces the risks of electrocution, power surges, equipment damage, and house fires.
