What is the Equipment Demand Load for a 12 kW kitchen range line and neutral?
The demand load would be 12 kW. When you talk about line and neutral you are referring to the voltage that the equipment operates on. In North America, an electric kitchen range operates on two voltages 120/240 volts. The 240 volts is obtained across two breakers in the distribution panel and the 120 volts is obtained between either 240 volt leg and the neutral. On a range of this size the 120 volts is usually used for the clock and controls for the range. The range at maximum would draw 50 amps, fed by a two pole 50 amp breaker using a #6 copper conductor with an insulation factor of 90 degrees C. The range will have an internal breaker or fuse to protect the 120 volt circuit.
How many amps in1 KW for a 240v sistem?
In a 240V system, 1 kW is equal to approximately 4.17 amps. This calculation is done by dividing the power in watts (1000 watts for 1 kW) by the voltage (240V) in the system.
What size wire and breaker for 8 kw heater?
For an 8 kW heater, you would typically use 10-gauge wire with a 30 amp breaker. Always consult the manufacturer's specifications and local electrical codes to ensure proper sizing and installation.
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 watts is 8 amps at 240 volts?
8 amps at 240 volts is equal to 1920 watts. This calculation is done by multiplying the current (8 amps) by the voltage (240 volts) to get the power in watts.
What size wire and breaker for a 240 volt single phase 20 kw electric furnace rated at 83.3 amps?
AWG #3 copper.

What size of wire do you need for 5 kw heat strip?
120 15 amp service ? 210 7 amp service ?
What size wire for 10kw 240 volt?
10 mm2 cross section should be sufficient (#6 wire?)
What is breaker size for 62.19 KW 3 phase?
A breaker protects the wire size of the feeder that is connected to it. The amperage of the load must be found. Without a voltage stated the amperage from the wattage given can not be calculated. The equation for amperage when the kw is given is A = kW x 1000/1.73 x volts x pf. The pf constant to use is .9.

In a 240V system, 1 kW is equal to approximately 4.17 amps. This calculation is done by dividing the power in watts (1000 watts for 1 kW) by the voltage (240V) in the system.
What size wire and breaker for 8 kw heater?
For an 8 kW heater, you would typically use 10-gauge wire with a 30 amp breaker. Always consult the manufacturer's specifications and local electrical codes to ensure proper sizing and installation.
What breaker size do you use for a 270 Kw power rated equipment and power supply of 380 vac 3 phase?
I=270000/380/1.732 I=410A USE: 500A CIRCUIT BREAKER
How do you calculate the dc circuit breaker rating for a given kw?
the given kw Divide by the your voltage
What size breaker should be used for a 3.6 kW oven?
3000 / 240 = Amps. You de-rate a breaker by 20 % for continuous load like an oven. You could get by with a 20 Amp breaker and 12 AWG wire. However, I would recommend 30 Amps and 10 AWG for an oven for the long run.
What size breaker do you need for 9000W at 440V 3phase?
This formula will give you the amperage I = kw x 1000/1.73 x E x pf (pf = power factor). Take the amperage and multiply it by 125%. This will give you the breaker size that you need.
How many watts can 14-2 wire run?
14 AWG wire normally supplies 15 amps. Watts = Volts x Amps x Power Factor. Power Factor has a maximum value of one. If you have a 120 volt circuit that would be 15 x 120 = 1800 watts or 1.8 KW. For a 240 volt circuit 3.6 KW.
