Answer
At 115 volts ac, 30 amps equals 3,450 watts.
To answer this question the voltage of the circuit from the 30 amp breaker must be given.
At 240V it can support 7200W
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.
if its a single current its 120v X 25 amp = 3000 watts
20 Amp * 120 Volts = 2400 Watts 2400 Watt * 80% max use = 1920 Watts planned normal usage for a circuit with a 20 Amp breaker.
15,000 watts at 240 volts will use 62.5 amps. Therefore you will need to use AWG #3 wire on a 100 amp breaker.
The formula you are looking for is Watts = Amps x Volts.
14 gauge will handle it with a 15 amp breaker. If you use 12 gauge use a 20 amp 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.
about 4800 watt but should not use it 100% so to be safe 4000 watt (80%)
if its a single current its 120v X 25 amp = 3000 watts
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.
20 Amp * 120 Volts = 2400 Watts 2400 Watt * 80% max use = 1920 Watts planned normal usage for a circuit with a 20 Amp breaker.
A 50 amp breaker is an overcurent device.
15,000 watts at 240 volts will use 62.5 amps. Therefore you will need to use AWG #3 wire on a 100 amp breaker.
Watts divided by voltage. Standard crockpot use 1-2 amp.
The formula you are looking for is Watts = Amps x Volts.
If you use a 20 amp breaker, you would need to use 12 AWG wire. If you use a 15 amp breaker, you could use 14 AWG. As always, make certain that you comply with all local wiring codes.
Breaker sizing is dependant on what the load amperage is that the breaker is connected to. If the amperage is not given but just the wattage, use this equation I = W/E. Amps = Watts/Volts. This air conditioner unit should be on a dedicated circuit receptacle. On these types of loads the conductor can only be loaded to 80% of the conductors rating. So a 15 amp breaker times 80% = 12 amps or Watts = Amps x Volts, 12 x 120 = 1440 watts. A 20 amp breaker times 80% = 16 amps or Watts = Amps x Volts, 16 x 120 = 1920. Once the breaker is sized remember to use the correct wire size to correspond with the amperage of the breaker.
