The maximum current capacity of a 120 amp breaker is 120 amps.
The maximum voltage rating for a 120/240 VAC breaker is 240 volts.
The maximum power capacity of a 15 amp 120 volt outlet is 1800 watts.
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.
The smallest size breaker is a 15 amp and with a #14 wire which has a capacity for 15 amps and a 120 volt source, this combination will give you the capacity up to 1800 watts. W = A x V, 120 x 15 = 1800.
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.
Your home electrical wall outlets current capacity is governed by the breaker that feeds that circuit. In most home situations the wall receptacles are fed with a 15 amp breaker. Dedicated outlets could have a higher ampacity as they are installed for specific appliances or devices. To check your circuit, plug a lamp into the outlet. Start flipping the breakers off. When the lamp goes out that is the breaker for that circuit. Look on the handle of the breaker and it will tell you the capacity of that particular circuit.
Rated current is typically defined for all electric devices. Either the device has a rated current, wattage or Volt x amperes (VA). Current can be computed by dividing the wattage or VA rating by 120 volts (For resistive loads). In residential situations the maximum current is governed by the protecting breaker on a circuit. If you all up all the rated currents for devices on a circuit they should be less than or equal to 80% of the protecting breaker current rating.
The 50 amp Eaton GFCI breaker is designed to protect against electrical shocks and overloads in circuits with a 50 amp capacity. It features ground fault protection and is compatible with Eaton panels. The breaker has a voltage rating of 120/240 volts and a short circuit current rating of 10,000 amps.
Electric current can be either direct or alternating. ... Current density can also be expressed in amperes. Depending where you live will depending on what the voltage is and the carried amps. In the U.S., a conventional 120 V outlet is rated for a maximum current of 15 A, and the upstream wiring and circuit breaker should be designed to tolerate that. In the UK: The maximum current that can be drawn from a single UK socket is 13 amps (13A) and the maximum that can be drawn from all the sockets on a single ring-main together is 32A.
Well it depends on the wattage of the bulbs. At 120 V, with power = current x voltage, you have power = (15 A) x (120 V) = 1800 watts. So if you have 100 W bulbs, then the maximum possible before the breaker should trip is 18 bulbs. It is not a good idea to operate near the limits of the circuit design, though.
6000amps <<>> The above answer must have big lugs to accommodate 6000 amp capacity wire. In my breaker catalogue the largest 120 volt single pole breaker is 70 amps, 277 volt single pole is 150 amps and 347 volt single pole is 100 amps. The 120 volt single pole breaker occupies two opposed slots because of its length.
Assuming 120 VAC in a residence maximum watts = 15 x 120 = 1800 Watts. For a continuous load you can support 1440 watts which is 80& of maximum. You need 14 AWG gauge wire.
