Understanding the Risks Behind Electrical Problems in Your Home
When it comes to home electrical issues, safety should always be your top priority. From flickering lights to tripped breakers, common electrical faults can disrupt daily life and even pose fire hazards. Whether you’re dealing with unexpected power surges or you’re just wondering what’s causing your outlets to stop working, it’s helpful to know what the most common type of electrical fault is—and what to do about it.
As trusted electricians serving Coeur d’Alene, Post Falls, Hayden, Rathdrum, Sandpoint, and Spirit Lake, we at J.A. Bertsch Heating, Cooling & Electrical are here to break down the most frequent electrical issues we see in homes and how you can stay safe.
Most Common Electrical Faults in Homes
1. Short Circuits
Short circuits are by far the most common and potentially dangerous electrical fault. They happen when a live wire comes into contact with a neutral wire, creating a surge of electricity. This often results in:
-
Sparks or popping sounds
-
A burning smell
-
Melted wire insulation
Left unresolved, short circuits can lead to electrical fires. If you’ve noticed repeated breaker trips in one area of your home, it could be a sign of this issue.
2. Ground Faults
A ground fault occurs when the electrical current strays from its intended path and flows into the ground. This usually happens when water or damaged wiring is involved. Ground faults are dangerous because they can cause:
-
Electrical shock
-
Appliance damage
-
Unexpected power losses
If you have GFCI outlets in areas like your bathroom or kitchen and they keep tripping, you may be experiencing ground faults.
3. Overloaded Circuits
An overloaded circuit happens when too many high-wattage appliances or devices draw power from a single line. It’s a common issue in older homes with outdated wiring and leads to:
-
Flickering or dimming lights
-
Buzzing sounds
-
Frequent tripping breakers
-
Warm or discolored outlets
To avoid this, try redistributing devices between different circuits and avoid using extension cords for major appliances.
4. Open Circuits
An open circuit is when a break in the wiring stops electricity from flowing altogether. This might not be as dangerous as a short circuit, but it can be a major inconvenience. Signs include:
-
Light fixtures that won’t turn on
-
Switches that no longer work
Open circuits are often caused by loose connections, damaged wires, or faulty outlets.
5. Arc Faults
Arc faults are less common but very dangerous. They happen when electricity jumps between wires or contacts, generating intense heat and possibly sparking a fire. Warning signs include:
-
Hissing or sizzling sounds
-
Warm wall plates
-
Burning smells near outlets
-
Unexpected power interruptions
AFCI (Arc Fault Circuit Interrupter) breakers are designed to detect and prevent arc faults before they cause major damage.

FAQs
What is the most common type of fault?
The most common type of electrical fault in residential homes is a short circuit. This occurs when a hot (live) wire touches a neutral or ground wire, causing a sudden surge of electricity. It’s one of the leading causes of circuit breaker trips, power loss, and electrical fires. Short circuits can be triggered by damaged wiring, faulty appliances, or aging electrical systems.
What is a common fault in an electrical circuit?
One of the most frequent faults in a household electrical circuit is an overloaded circuit. This happens when too many devices or appliances draw power from a single circuit, exceeding its capacity. It can lead to tripped breakers, flickering lights, or warm outlets, and is especially common in older homes without updated wiring.
What is the most common fault in the power system?
In the broader electrical grid or power distribution systems, the most common fault is a line-to-ground fault. This occurs when a live conductor touches the ground or a grounded object, often due to weather conditions like fallen tree limbs or lightning. In homes, this can present as ground faults, particularly in areas with high moisture like kitchens or bathrooms.
What is the most common type of electrical circuit?
The most common type of residential electrical circuit is a single-phase circuit, specifically 120V circuits used for standard lighting, outlets, and small appliances. These circuits are common because they safely distribute power throughout the home for most everyday electrical needs. Larger appliances may use 240V circuits, but single-phase systems remain the most prevalent.
What is the difference between a bolted fault and an arcing fault?
A bolted fault occurs when two conductors (or a conductor and ground) make solid, direct contact, allowing maximum current to flow—often triggering immediate circuit breaker trips. A fault arc, or arcing fault, happens when the connection is loose or intermittent, creating a high-temperature arc of electricity. Arcing faults are especially dangerous because they often go unnoticed and can lead to electrical fires over time. Both faults require professional inspection and repair.
