If you've ever opened your electrical panel and noticed a breaker that looks like two switches sharing the same slot, you're likely looking at a tandem circuit breaker. These breakers are a clever solution for adding more circuits without upgrading to a larger panel — but they aren't right for every situation.
Each switch is connected to a separate circuit, but they share a common trip mechanism and bus connection. This design allows for twice the number of circuits in the same amount of panel space, which can be especially helpful in older homes where panel space is at a premium. When Are Tandem Breakers Used?
No. Not all electrical panels are designed to accept tandem breakers. Using them in the wrong panel can lead to safety hazards and code violations. To know if your panel supports tandem breakers: Look for a label inside the panel door that lists approved breaker types. Panels rated for tandem breakers will often have designated slots for them.
