Why does my circuit breaker keep tripping? Causes and solutions

A circuit breaker that keeps tripping is more than just an inconvenience. It's your electrical system's way of protecting your home from potential hazards, such as overheating wires, electrical fires, and damaged appliances. While an occasional trip may not be cause for concern, a frequent breaker trip are signs that something needs attention.

In this guide, we'll cover the most common causes circuit breakers trip, how to identify the problem, and what solutions are available to keep your electrical system running safely.

Common Reasons Your Circuit Breaker Keeps Tripping

1. Circuit Overload

   1. Circuit overloads are the most common cause of breaker trips. An overload occurs when too many devices or appliances draw power from the same circuit at once. The breaker senses the excessive current and shuts off power before the wiring can overheat.

2. Short Circuit

   1. A short circuit occurs when a hot wire comes into contact with a neutral wire, creating a sudden surge of electrical current. This causes the breaker to trip immediately as a safety precaution. Signs of this is a breaker tripping instantly after resetting, burnt smell near outlets, and sparking when plugging in equipment.

3. Ground Fault

   1. Ground faults are similar to a short circuit but occur when a hot wire touches a grounded metal component such as an electrical box or appliance housing. Ground faults are especially common in areas exposed to moisture such as bathrooms, kitchens, garages, and outdoor outlets.

4. Faulty Appliances

   1. Sometimes the problem isn't the electrical system at all. A damaged appliance can draw excessive current or create an internal short circuit. Common offenders include space heaters, microwaves, refrigerators, air conditioners, hair dryers and power strips.

5. Loose or Damaged Wiring

   1. Overtime, wiring can loosen, deteriorate, or become damaged by age, pests, renovations, or corrosion. Loose connections generate heat and can cause intermittent breaker trips that become more frequent over time. This can present itself as flickering lights, buzzing sounds from outlets and switches, burning odors, and warm electrical panel components.

6. Arc Faults

   1. An arc fault occurs when electricity jumps between damaged or loosely connected wires. This electrical arcing creates significant heat and can become a fire hazard. Signs of this include intermittent power loss, flickering lights, and crackling sounds behind walls.

7. An Aging or Failing Circuit Breaker

   1. While breakers are built to last for many years, they can eventually wear out. A breaker that trips too easily or won't remain reset may have been reached the end of its service life. You will know a breaker is bad if it won't stay reset, visible damage to the breaker, burning smells from the panel, or breakers feeling unusually hot.

When Should You Call An Electrician?

A circuit breaker that keeps tripping is your home's built-in warning system. Whether the cause is an overloaded circuit, faulty appliance, damaged wiring, or an aging breaker, repeated trips indicate that something needs attention.

You should contact a licensed electrician if:

• The breaker trips immediately after resetting

• You notice burning smells or scorch marks

• Lights flicker frequently

• Outlets feel warm or hot

• The same breaker trips repeatedly

• You're unsure what's causing the problem
