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.

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.

∙ 6y agoA 20 amp breaker on 120 volts will trip the breaker when the total wattage goes over 2,400 watts. But you should never load the circuit more than 80% which would be 1920 watts.

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 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).
If a 120 volt current is protected by a 25 amp circuit breaker What is the largest number of watts an appliance can safely use?
The largest number of watts an appliance can safely use on a 120V circuit protected by a 25A breaker is 3000 watts. You calculate this by multiplying the voltage (120V) by the amperage (25A). This gives you a maximum power capacity of 3000 watts on this circuit.
How many watts can a 240 volt 30 amp breaker carry?
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.
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?
A 20 amp breaker can handle up to 2400 watts per hour (20 amps x 120 volts = 2400 watts).
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
If a 120 volt current is protected by a 25 amp circuit breaker What is the largest number of watts an appliance can safely use?
The largest number of watts an appliance can safely use on a 120V circuit protected by a 25A breaker is 3000 watts. You calculate this by multiplying the voltage (120V) by the amperage (25A). This gives you a maximum power capacity of 3000 watts on this circuit.
How many amp circuit breaker for 3 hp 230 volt motor?
16A
How volts comes from a 20amps breaker?
On most residential circuit breaker boxes in North America, each individual breaker represents one 120-volt circuit. Two breakers ganged together represent a 240-volt circuit.

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 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 250 volt circuit run at 30 amps?
The formula you are looking for is W = I x E, Watts = Amps x Volts.
What circuit breaker to install for 10 amp 250 volt circuit?
For a 10 amp, 250 volt circuit, you should install a circuit breaker rated for at least 10 amps and 250 volts. A common option would be a single-pole, 10 amp circuit breaker designed for 240-250 volt applications. Be sure to check the specifications and compatibility with your specific electrical panel.
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.
