What is Double Pole Breaker?
A Double Pole Breaker is a type of circuit breaker designed to control two separate 120-volt hot wires at the same time, delivering a total of 240 volts to high-powered appliances or equipment. This breaker is essential in residential and commercial electrical systems where large loads, such as electric water heaters, dryers, HVAC systems, or ranges, require a full 240-volt supply.
In practical terms, a double pole breaker snaps into both hot bus bars in a service panel, allowing it to shut off both hot wires simultaneously. This ensures that in the event of a short circuit or overload, the entire 240-volt circuit is de-energized, enhancing safety and preventing electrical hazards. Double pole breakers are a fundamental component in maintaining code-compliant, safe installations for high-demand systems.
