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.

∙ 12y agoi have a 4800 watt heater that's 240 volts. What size breaker is needed?
Wiki User
∙ 14y ago240V x 30A = 7.2kW
or the more general formula:
Volts X Amps = Watts
Wiki User
∙ 12y agoDepends on the voltage. Watts = volts x Amps
On 110 volts = 3300 watts.
Wiki User
∙ 13y agoThe formula you are looking for is W = I x E. Watts = Amps x Volts.

How many watts can a 10amp 240 volt switch carry?
2304w
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.
How many watts can a 20 amp breaker handle per hour?
2.3 kw per hour on a 110-120 volt circuit.
How many watts is 1 v?
One volt is zero watts.
How many watts does a 36 volt battery charger use?
Not sure about how many Watts your 36 volt charger uses, but you can find out by this formula... Volts X Amps = Watts.
How many watts can a 10amp 240 volt switch carry?

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 does my 12 volt 2 amp battery charger draw?
Volts * Amps = Watts 12 Volt * 2 amp = 24 Watts
How many watts does a 3 amps use in America?
On a 120 volt supply, up to 360 watts. On a 240 volt supply, up to 720 watts.
How many watts need for seven ampere's and 120 volt's?
770 watts.
How many watts can be put on a 20 amp 208 volt circuit breaker?
20-amp breakers can be found for many different voltage levels. The higher-voltage ones tend to be more expensive. A breaker can be used in a circuit of equal or lower voltage than the rated voltage of the breaker.
How many volts can you draw off of a 15amp breaker?
It's the amps that are controlled by the breaker not the volts. You can have a 600 volt 15 amp breaker, you can have a 347 volt 15 amp breaker. The breaker will trip when you exceed 15 AMPS.
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
