A two pole breaker clips to adjacent buss in the breaker panel, supplies 240 volt power to equipnent like clothes dryers and air conditoning.The breakers have a mechanical common trip so if either pole exceeds its current rating both lines are opened shutting down the equipment.Each pole can carry up to its rated current of 30 amps.Hope this helps.

SteveGood question. A 30 amp two pole breaker allows up to 30 amps per leg or phase to conduct in fact provided a "total" of 60 amps. However, 220 volt devices require the rated amperage for each leg. So a device which requires 220 volt and 60 amps requires a two pole 60 amp breaker and the correct wire size to feed it.

How many watts will a 30 amp two pole breaker handle at 240 volts?
30X240=7200
How many watts will a 60 amp 2pole breaker handle?
A 60 amp 2-pole breaker can handle up to 14,400 watts (60 amps x 240 volts). This is because a 2-pole breaker provides 240 volts, which is the typical voltage for larger appliances and machinery.
How many watts will a 20 amp douple pole breaker handle?
The formulae for calculating watts to amps is Watts divided by Voltage. Therefore to get from Amps to Watts the calculation is Amps × Voltage. Therefore if you are working on a 240 volt supply the calculation is 20 (Amps) × 240 (Volts) which = 4800 watts.
Is 30 amp double pole breaker ok for 4800 watt wall heater?
Yes, a 30 amp double pole breaker would be suitable for a 4800 watt wall heater. Since watts equals volts multiplied by amps, this wall heater on a 240-volt circuit would draw 20 amps (4800 watts/240 volts), which is less than the 30 amp capacity of the breaker.
Does a double 50 amp breaker make a 100 amp?
No, a double pole 50 amp breaker protects a 240 volt supply at 50 amps. The number that is on the handle of the breaker is the amperage that the breaker will trip at if an overload occurs on the circuit.
