Double pole vs single pole breaker. A circuit breaker that is connected to a 110 volt circuit is called a single pole breaker. They are constructed with one hot wire and one neutral wire. They are not interchangeable with single pose circuit breakers. Single pole breakers are thinner and have a single switch for onoff positions. Well single pole breakers and double pole breakers differ in the voltage and amperage they provide as well as how they are wired. A double pole breaker will have the appearance of double the width of the single pole breaker with the appearance of two switches bridged to function as a single switch.
Their advantage is that they provide two different circuits. Double pole circuit breaker is like having 2 single pole circuit breakers. Double pole breakers will also require twice the space in a breaker panel as their single pole counterparts. I would not use a double pole for two seperate circuits. A single pole breaker is typically used with 120 volt circuits 15 20 amps. The circuit breaker the wire and the wire insulation are all designed to work together as a system.
A double pole breaker is primarily used with a 240 volt circuit 20 60 amps and consists of two hot wires.
