In a residence assume you are referring to 120 volt supply. Watts = amps x volts x Power Factor. Now Power factor is one for resistive loads like incandescent light bulbs. Power Factor can vary from zero to one when inductive loads like motors are added. So the maximum theoretical wattage would be about 15 A x 120 V. However, you de-rate a breaker to 80% of capacity so as not to continually trip breaker. Therefore, the answer you are looking for in a practical sense is 120 x 15 x .8 = 1440 watts or 1.44 kilowatts.

How many amp breaker is needed for 4000 watts at 220 volts?
The equation that you are looking for is I = W/E. Amps = Watts / Volts.
How many watts can a 20 amp breaker handle per hour?
A 20 amp breaker can handle up to 2400 watts per hour (20 amps x 120 volts = 2400 watts).
How many watts will a 30 amp two pole breaker handle at 240 volts?
30X240=7200
How many watts can be on a 15amp breaker?
At 120 volts a 15 amp breaker can be loaded to 1800 watts before it will trip. If it is a continuous load then the electrical code states that it is only allowed to be loaded to 80%. This will be 1800 x .8 = 1440 watts. If the voltage is not 120 volts use the following equation Watts = Amps x Volts. Amps being the breaker size that is to be used.
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.
