Tandem Breakers: What They Are and Why San Dimas Homeowners Need to Know
Posted on July 27, 2026 by Just Electric Services
What are Tandem Breakers?
Living in San Dimas, California – known for its beautiful Spanish-style homes nestled amongst rolling hills and sunny weather - means understanding your home’s systems. One critical component often overlooked is the breaker panel. And sometimes, homeowners attempt to "improve" their electrical system by installing something called a tandem breaker (also referred to as a “cheater”). A tandem breaker is essentially an extra switch installed in line with a circuit breaker. It looks like a regular breaker but doesn’t trip when overloaded – it simply stays on.
This seemingly small modification can create significant problems, often posing serious safety hazards. While the intention might be to add more outlets or power, it's rarely done correctly and drastically increases the risk of electrical fires.
Why Tandem Breakers Are Dangerous
- Overheating Wires: The primary danger is that a tandem breaker doesn’t interrupt the flow of electricity when there's an overload. This causes wires to overheat, leading to insulation damage and eventually, fire.
- False Security: They provide a false sense of security – you might think you have more power, but it’s hidden danger waiting to happen.
- Code Violations & Insurance Issues: Installing tandem breakers is almost always a violation of electrical codes and can void your homeowner's insurance policy if a fire results. The San Dimas area has strict building standards for a reason!
- Increased Risk in Our Climate: With California’s dry climate and frequent heatwaves, overloading circuits becomes even more critical to avoid – tandem breakers exacerbate this risk significantly.
When You Might Need an Emergency Electrician San Dimas
If you suspect a tandem breaker has been installed in your home or are experiencing any of the following issues, it's crucial to act quickly: flickering lights, tripped breakers repeatedly (even after resetting), burning smells near outlets, or overheating electrical panels. These could be signs of an overloaded circuit caused by a hidden tandem breaker.
