What is a 2 pole 30A circuit breaker?

Answer 1

Answer for USA, Canada and countries running a 60 Hertz supply service.

On a split phase system where you need 240 volts a two pole breaker is used. L1 to N will give you 120 volts for one circuit. L2 to N will give you 120 volts for one circuit. L1 to L2 will give you 240 volts for one circuit.

Answer 2

A two pole 20A circuit breaker can be used for any 240V load that requires 20A, with supply conductors no smaller than 12AWG. Since a clothes dryer typically requires 30A, and a range 40A to 50A, a 20A 240V circuit could probably be a window air conditioner, pool pump, or some other 20A 240V load.

Answer 3

This is a device that monitors either two separate, but related, circuits or one higher voltage single circuit for overcurrent conditions. American household circuits use both 120 volt and 240 volt wiring. For example, most electric water heaters and electric stoves are designed for 240 volts, although the stove might have a light bulb or fan that uses 120 volts. Both conductors must be disconnected together even if for some reason an overcurrent only occurs in one conductor. Therefore, most 2 pole circuit breakers have a linked handle or other method to make sure both poles turn off simultaneously.

Answer 4

A 2 pole 30A circuit breaker is a type of electrical protection device designed to interrupt the flow of electricity in a circuit if a fault is detected. "2 pole" means it has two sets of connections for both the hot and neutral wires, and "30A" indicates it can handle a maximum current of 30 amps before tripping. This type of breaker is commonly used for larger appliances or circuits that require more power.

Answer 5

A 2 pole 30A circuit breaker is a device that is used to supply a 240 volt power source for a device that operates on 240 volts and under 30 amps of current draw
