Differences Between Tandem and Single Breakers
The primary difference between tandem circuit breakers and single breakers lies in their configuration and functionality. A single breaker typically manages one circuit, while a tandem provides the functionality of two circuits in one slot. This means that with tandem breakers, you achieve better space utilization. Additionally, tandem breakers can only operate at 120 volts per circuit, unlike double-pole breakers that can manage 240 volts. If you're considering upgrades or modifications to your electrical system, you may find tandem breakers offer a cost-effective solution for expanding your service without requiring a complete panel replacement.
How Tandem Circuit Breakers Work
Tandem circuit breakers operate by connecting two separate breakers within a single housing. Each pole of the tandem breaker connects to individual circuits on a 120-volt bus bar. Despite being installed together, the circuits remain independent of each other. It’s important to note that you cannot toggle both switches together to create a 240-volt circuit. For installations requiring 240 volts, two adjacent tandem breakers may be used with a connecting toggle. Choosing the right kind of breaker is crucial for ensuring safety and compliance, which is best handled by professionals like AAA Electrical Services.
