7200 Watts, but that is only the trip value of the breaker. The circuit should only sustain 80% of the rated load, so a 240 volt 30 amp circuit can carry 5760 watts.
answer 2 Both a circuit breaker and a fusible link are current operated, not wattage operated. So 7200 watts is the answer to the stated question. But the correct answer is 30A.
HOWEVER if it is not a CB or fuse, but an electrical outlet that is concerned, then you should not overload the outlet (wall socket). If it says 30 Amp, then that's it.
Similarly if it is a cable or wiring that is being inquired about. The 240 volt refers to the insulation value of the cable, the 30 Amp refers to the current carrying capacity of the conductor.
The question is not perfectly clear.
A 240 volt 30 amp breaker can carry a maximum of 7200 watts (240 volts * 30 amps = 7200 watts).
i have a 4800 watt heater that's 240 volts. What size breaker is needed?
240V x 30A = 7.2kW
or the more general formula:
Volts X Amps = Watts
Depends on the voltage. Watts = volts x Amps
On 110 volts = 3300 watts.
The formula you are looking for is W = I x E. Watts = Amps x Volts.
3600 watts when part of a 120 v circuit. Multiply voltage times the amperage to get watts.

How much 1200 watts on one breaker?
Not a whole lot. Assuming that is 120 volt power, 1200 watts would be 10 amps. A standard breaker is 15 amps.
What size breaker for a 1500 watt 120 volt heater?
To calculate the breaker size for a 1500-watt 120-volt heater, use the formula: Breaker size = Power (Watts) / Volts. In this case, 1500 watts / 120 volts = 12.5 amps. Therefore, you would need a 15-amp breaker for a 1500-watt 120-volt heater to allow for a safety margin.
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 can a 10amp 240 volt switch carry?
A 10 amp switch connected to a 240 volt circuit can carry up to 2400 watts (10 amps x 240 volts = 2400 watts). It's important to ensure that the switch is rated for the anticipated load to prevent overheating or failure.
Why will too many electrical devices operating at one time after blow a fuse or trip a circuit breaker?
The load exceeds the limit of the breaker or fuse. For example a 20 amp breaker on a 120 volt circuit will handle 2400 watts. Exceed that wattage and the breaker will trip or the fuse will blow.
How much 1200 watts on one breaker?
Not a whole lot. Assuming that is 120 volt power, 1200 watts would be 10 amps. A standard breaker is 15 amps.
What size breaker for a 1500 watt 120 volt heater?
To calculate the breaker size for a 1500-watt 120-volt heater, use the formula: Breaker size = Power (Watts) / Volts. In this case, 1500 watts / 120 volts = 12.5 amps. Therefore, you would need a 15-amp breaker for a 1500-watt 120-volt heater to allow for a safety margin.
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 can a 10amp 240 volt switch carry?
A 10 amp switch connected to a 240 volt circuit can carry up to 2400 watts (10 amps x 240 volts = 2400 watts). It's important to ensure that the switch is rated for the anticipated load to prevent overheating or failure.
Why will too many electrical devices operating at one time after blow a fuse or trip a circuit breaker?
The load exceeds the limit of the breaker or fuse. For example a 20 amp breaker on a 120 volt circuit will handle 2400 watts. Exceed that wattage and the breaker will trip or the fuse will blow.
How many watts need for seven ampere's and 120 volt's?
770 watts.
How many amps does a 60 hp 460 volt motor draw?
750 watts per horse power20 x 750 = 15,000 watts / 220V = 68A68 amps at 220 volts
How many watts can be put on a 20 amp 208 volt circuit breaker?
A 20 amp circuit breaker at 208 volts can handle up to 4160 watts (20 amps x 208 volts = 4160 watts). This is calculated by multiplying the amperage by the voltage to determine the maximum wattage capacity of the circuit.
How many light cans can a circuit hold?
you just have to do some math. if the can lights are the only thing on the circuit then times the wattage of each bulb by the total bulbs and only put 80% of the circuit breaker max on the line. ie 20 amp breaker and 120 volt power equals 2400 watts max. 80% of that is 1920 watts. 15 amp breaker and 120 volt power equal 1800 watts max. 80% of that is 1440 watts. if there are already other item on the circuit then you should test the line fully loaded with an amp clamp to see what its carrying already, and then deduct that from your totals
How many amperes in a watt and how many watts in a volt?
Amps, volts and watts are interrelated, but you need to do a little math. Amps * Volts = Watts
How many watts in 1 ampere 230 volt?
Watts = Amps X Volts Grab your calculator!
How many watts does my 12 volt 2 amp battery charger draw?
Your 12 volt 2 amp battery charger draws 24 watts of power (12 volts x 2 amps = 24 watts).
