Tandem Breakers: A Commerce, CA Electrician Explains!

Posted on January 25, 2026 by Just Electric Services

What are Tandem Breakers (Cheaters)?

Living in Commerce, California, means dealing with a unique combination of challenges when it comes to your home’s electrical system: hot summers that strain your AC and occasionally stormy weather. As a trusted electrician near me for over 25 years – based here in Covina and serving the entire San Gabriel Valley including Glendora and Pasadena – Just Electric Services has seen countless homes with this common, yet often misunderstood, issue: tandem breakers, sometimes called “cheaters.”

How Do Tandem Breakers Work?

A tandem breaker is essentially a double circuit breaker installed in series. It looks like a single standard breaker but actually contains two individual circuits behind a common switch. Typically, they’re found in older homes, especially those built with traditional wiring – think of the many beautiful craftsman-style houses and mid-century modern designs prevalent here in Commerce.

  • They're designed to allow you to control multiple appliances or lighting fixtures from one switch.
  • However, they create a significant overload risk if too many high-wattage devices are switched on simultaneously.

The Risks of Tandem Breakers

Because tandem breakers don't automatically trip when overloaded, they can allow excessive current to flow through the wiring. This leads to:

  • Overheating of wires and connections.
  • Potential fire hazards – a serious concern given Commerce’s dry summers.
  • Damage to electrical panels and appliances.

Many homeowners don't realize this risk, especially when only using one or two devices at a time. But during peak times like running an air conditioner, powering lights, and charging electronics, the cumulative load can quickly exceed what the breaker is designed to handle.
