That's easy. Depending on the amount voltage will determine the amount of wattage, since we know the value of the current. Lets take 120 VAC times 15 Amps = 1800 watts. When my wife and me have the small electric heater running in the bedroom during the morning before and she uses her hair dryer, it blows the breaker. Then I have to run downstairs and reset the breaker. The heater runs at around 9 Amps and the hair dryer draws around 10 Amps. 19 Amps blows the breaker. The more it blows the weaker it gets. Why would one want to know the amount of wattage on a breaker, when mainly were interested in the amonut of current ratings.

Can a 15 amp breaker hold 300 watts at 120 volts?
Yes, it can.
How many 15 amp receptacles can you put on a 15 amp breaker?
The NEC does not limit the receptacles in a residents. Industrial it is limited to 180 watts each.
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.
Can you run a 1000 watts light bulb with a 20 amp breaker 120v?
Yes, considering you can do that on 15 amp breaker easy.Experience in construction field. The worst that will happen is that the breaker will trip off after a few minutes.In the formula W = A x V. W = 20 x 120 = 2400 watts. If you want you can operate two 1000 watt lamps from a 20 amp breaker operating on 120 volts.
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.
Can six recessed lights of 50 watts be on a 15 amp breaker?
Should be fine if that is all that is on the breaker.
Can a 15 amp breaker hold 300 watts at 120 volts?
Yes, it can.
What is the wire size required for 1800 watts for lamps?
14 gauge will handle it with a 15 amp breaker. If you use 12 gauge use a 20 amp breaker.
How many 15 amp receptacles can you put on a 15 amp breaker?
The NEC does not limit the receptacles in a residents. Industrial it is limited to 180 watts each.
Can you use 14 wire for a light off a 20 amp circuit?
Yes, in home wiring as long as it is protected by a 15 amp breaker. Remember this circuit will only handle 1800 watts and cannot be loaded to any more than 1440 watts. So if each light is 75 watts then the maximum you can install is 19.

If installing several base board heaters with various watts what is the max number of watts you can put on one 20 amp 240v breaker?
For safety reasons ( and the National Electric Code) never put more than 75% load on a breaker, so for you case, 20 amp breaker x 75% = 15 amps 15 amps x 240 volts = 3600 watts 3600 watts
How do you turn a 30 amp circuit into a 15 amp cicuit?
Replace the 30 Amp Breaker with a 15 Amp breaker.
Can you run a 1000 watts light bulb with a 20 amp breaker 120v?
Yes, considering you can do that on 15 amp breaker easy.Experience in construction field. The worst that will happen is that the breaker will trip off after a few minutes.In the formula W = A x V. W = 20 x 120 = 2400 watts. If you want you can operate two 1000 watt lamps from a 20 amp breaker operating on 120 volts.
What size amp circuit breaker do you use on a 55 watt fluorescent light?
A 55 watt fluorescent light only pulls 0.4 amps. Lights can be installed on a 15 amp breaker using 14/2 wire. A maximum of 1440 watts is all that is allowed on a 15 amp circuit.
What amp breaker do you use to run 1000 watt light bulb?
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.
Is it possible to operate two 1300watt hairdryers on a 120volt circuit without blowing a fuse?
well if you have a 30 amp breaker yes. 1300 watts is basically 120 volts at 10.8 amps. most common house hold breaker are 15 amp or 20 amp. so if you are honestly pushing a breakers limits with one hair dryer let alone two. a 15 amp breaker it capable of making 1800 watts. also you have to take into account that the power you are using is making heat which actually draws more then a normal device that's rated at 1300 watts hope i helped
