ARC Faults – What Colorado Homeowners Need to Know

You probably do not think much about the electrical wiring hidden behind your walls. But when wires loosen, cords fray, or connections wear out, they can produce arc faults—tiny but potentially dangerous electric arcs that generate extreme heat.

These sparks may not trip a regular breaker, but they can ignite insulation or wood in seconds.

That is why modern safety codes require arc fault protection through arc fault circuit breakers (AFCI breakers).

At The Electricians, we install and service these life-saving devices across Colorado to help keep families safe from electrical fires.

What Is an Arc Fault?

An arc fault occurs when electricity jumps between damaged or loose conductors instead of flowing smoothly. The result: sparking, or electric arcs, that release intense heat.

There are two main types:

• Series arcs – happen when a single wire has a break or loose connection.
• Parallel arcs – occur when current jumps between two conductors, like hot to neutral.

Both conditions are dangerous. Unlike short circuits, arcs may continue for long periods without tripping a standard breaker, which is why specialized protection is essential.

What Is Arc Fault Protection?

Arc fault protection is provided by arc fault circuit interrupters (AFCIs), also called arc fault breakers. These devices constantly monitor current patterns. When they detect the unique signature of a dangerous arc, they trip immediately.

• Standard breakers only respond to overloads or short circuits.
• AFCI breakers respond to arcs, even at lower current levels.
• Combination AFCI breakers provide the highest level of protection, guarding against both parallel and series arcs.

By shutting down the branch circuit before fire can ignite, AFCIs add an essential layer of defense.

Where Are Arc Fault Breakers Required?

The National Electrical Code (NEC) requires AFCI protection in most living spaces. In Colorado homes, this includes:

• Bedrooms
• Living rooms
• Dining areas
• Family rooms and dens
• Hallways

Bathrooms, kitchens, garages, and outdoor areas may instead require ground fault circuit interrupter (GFCI) protection.

In some cases, a dual-function breaker can provide both AFCI and GFCI protection in one device.

How Arc Fault Breakers Are Installed

Installing an AFCI breaker is not a DIY job—it involves working directly inside your home’s electrical panel. A licensed electrician from The Electricians handles the process safely and according to code:

1. Inspect the Panel – Verify space and compatibility for AFCI breakers.
2. Remove the Old Breaker – The outdated breaker disconnects from the branch circuit.
3. Install the AFCI Breaker – The new breaker connects properly to the neutral wire and hot wire.
4. Test the Circuit – Simulate arc conditions to ensure correct response.
5. Check for Code Compliance – Confirm installation meets NEC and Colorado building standards.

DIY attempts risk nuisance tripping, wiring errors, or worse—serious injury. Leave this one to professionals.

Benefits of Arc Fault Circuit Breakers

• Fire Prevention – Stops one of the most common causes of residential electrical fires.
• Code Compliance – Meets modern NEC requirements for Colorado homes.
• Peace of Mind – Protects areas where your family sleeps and spends time.
• Resale Value – Buyers appreciate updated, code-compliant electrical systems.
• Reduced Risk of Dangerous Arcs – Prevents both series and parallel arcs before they escalate.

FAQs About Arc Faults

What is an arc fault?

An arc fault is an unintended electrical discharge caused by damaged wires, loose connections, or deteriorating insulation.

What is arc fault protection?

Arc fault protection comes from AFCI circuit breakers that detect and shut off current when dangerous arcs appear.

Where are arc fault breakers required?

The NEC requires them in most habitable rooms, including bedrooms, living rooms, and hallways.

How do you install an arc fault breaker?

A licensed electrician installs the AFCI breaker into the main panel, connecting both hot and neutral wires, then tests for proper operation.

Why does my AFCI keep tripping?

This can happen due to nuisance tripping from electronics or actual dangerous conditions like loose wiring. A professional can diagnose the cause.
