How to calculate a cable size of 3kw motor
What is the speed of a 3kW electric motor?
The speed of motion generated by a motor is not a function of its nominal power. The nominal power, 3kW in this example, is an indicator for the electric power consumed, and for the force available in the direction of motion. The speed of a motor is determined by its construction, and can cover an extremely wide range regardless of its power.
What would be the resistance of and the current drawn by a 3kw 240 v immersion heater?
Power = E2 / RResistance = E2 / power = (240)2 / 3,000 = 19.2 ohmsCurrent = E / R = 240 / 19.2 = 12.5 amperes
What Generator size is needed for 10 hp 480 volt 3 phase motor?
Watts and horsepower are directly related as they are both measurements of power. 1hp = 745.6998 watts. So 3kW = 3000W / 745.6998 W/hp = 4.023hp You need a minimum of 4hp, which will give you a max of 2982W before any losses in your generator. You should probably go with a 4.5 or 5 horse motor.
How many amps does a HP motor V 3 phase pull?
The 50hp motor has a current rating of 55.4 amps if its power factor is 0.8.Another Answer:One horsepower (electric motor) is 746 watts, so 50 horsepower is 37.3 KW. Assumed power factor is 0.8, so divide by 0.8 to get 46.6 KVA. Assumed efficiency is 0.95, so divide by 0.95 to get 49.1 KVA. The motor is three phase, so divide by three to get 16.4 KVA per winding. It is 480V so divide by 480 to get 34.1 amperes per winding. Assumed configuration is to run on delta, so multiply by 1.732 (square root of 3) to get 59.0 amperes per phase. This is very close to the 55.4 stated before.

How to calculate a cable size of 3kw motor
What is the cable size for a 3KW motor 350 meter run for cable 240v?
For a 3KW motor with a 350-meter run and 240V supply voltage, you would typically need a cable size of around 16mm² for proper voltage drop considerations and to prevent overheating. It's recommended to consult with a qualified electrician or use a voltage drop calculator to determine the exact cable size needed for your specific installation.
What size of cable will you need for a 3 phase panel running 3 3kw motors?
To answer this question a voltage must be stated.
How many amps does 3kW geyser draw?
Assuming no other factors are considered, a 3kW geyser would draw approximately 13 amps of current on a standard 230V electrical supply. This calculation is based on the formula: Power (in watts) = Voltage (in volts) x Current (in amps).
How much electricity does a 150 liter geyser use?
It depends on the element size that heats the water. The average 150L geyser uses a 3kW element, which will take about 2.5h to heat the water from cold to 70'C. If you "empty" the geyser twice daily, which is an unlikely maximum, it'll use 15 kWh of electricity.
What size fuse is needed for a 3kw heater?
A 13 Amp fuse (brown) is needed for a 3kw heater. <<>> Answer for USA, Canada and countries running a 60 Hz power supply service. 3000 watts at 120 volts = 25 amps, 3000 watts at 240 volts = 12.5 amps.
How do you size a fuse?
The fuse protects the cable it is feeding therefore in UK upto 10A for 1.0mm cable, upto 15A for 1.5mm cable and upto 20A for 2.5mm cable. This is for installation type (solid core copper) cable not flex. In the UK and the rest of the EU (230V) 1 Kw load = 4A so 5A fuse should be OK. 2KW = 8A, 3KW = 12A so use 13A Fuse.
How much watts for 2 ton AC?
3KW
What size of wire you need to feed commercial kitchen equipment three 3kwovens a 20kw water heater and 3kw deep fryer?
You should contact a certified, and licensed electrician.
How many watts are there in 3 kw?
3kW is 3,000 watts.
What is the fuse rating for 3kw immersion heater?
The fuse rating for a 3kW immersion heater is typically 13 amps. This is based on the formula that calculates the current draw (I) using the power (P) and voltage (V): I = P/V. For a standard UK voltage of 230V, a 3kW heater would draw approximately 13 amps. It's important to ensure that the circuit is also properly rated to handle the load.
What is the formula for calculating the full load current of 3kW motor?
The formula you are looking for is I = Watts/ Voltage, I = 3000/voltage.
