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 is primarily used with a 240 volt circuit 20 60 amps and consists of two hot wires.
Ge Q Line 90 Amp 2 In Double Pole Circuit Breaker
Single pole vs double pole breaker. A more complex setup 4 wires are required allow for the power to be switched off completely. Double pole breakers will also require twice the space in a breaker panel as their single pole counterparts. Unlike the single pole setup the power supply of a double pole isnt directly tied to the heater its powered by a separate circuit. The circuit breaker the wire and the wire insulation are all designed to work together as a system. Single pole breakers are thinner and have a single switch for onoff positions. The rating is marked on the switch and it must be the same as or preferably higher than the current draw for the device it controls.
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. Circuit breakers come in several styles including the standard single pole breakers that serve 120 volt household circuits and double pole breakers that take up two slots in a breaker box and serve 240 volt appliances. They are constructed with one hot wire and one neutral wire. A circuit breaker that is connected to a 110 volt circuit is called a single pole breaker. A single pole breaker is typically used with 120 volt circuits 15 20 amps. Single pole circuit breakers supply 120 volt power to circuits while double pole circuit breakers supply 240 volts.
Provide 120 volts 15 20 amps and have one hot wire and one neutral wire. No batteries no power stealing. The other option is a double pole thermostat. Its rated for a higher current. Provide 240 volts 20 60 amps and have two hot wires that share one neutral wire. Double pole wiring apart from the fact that it accepts two pairs of hot wires a double pole switch is different from a single pole one in another important way.
