Double-pole breakers have two hot wires that are connected by a single neutral wire. That means if there's a short circuit on either of the poles' hot wires, both trip. These breakers can be used to serve two separate 120-volt circuits or they can serve a single 240-volt circuit, such as your central AC's circuit.
Do I need a single or double pole breaker?
The main difference between a single vs double pole breaker is their power capacity. Single-pole breakers are typically used for low-power appliances, as they can provide 15 to 20 Ampereges and 120 Volts. Double-pole breakers protect heavy machines, as they can provide 20 to 60 Ampereges and 240Volts.
Generally, there are two hot wires connected with a single neutral wire in a double pole breaker. That means if one of the hot wires has a short circuit, both trips. This can be used for the service of two separate 120 Volt circuits or a single 240 Volt circuit.
