How many amps required to run a single phase 4 ton air conditioner?

∙ 13y ago
Every piece of equipment is different depending on the age and size of the equipment. Older machines usually require more electricity than a comparable unit that is new of the same size. Example; I had a 1and 1/2 ton condensing unit that was here when I bought my house which required a minimum circuit ampacity of 2pole 30amp breaker. I purchased a new 3 ton unit that only requires a 2pole 25amp breaker and when in use the compressor is only pulling about 17 amps by my clamp on amp meters reading.( That is on each leg) So the newer equipment is much more efficient than older equipment and a lot less costly to

How many amps in 17000 watts?
At 240v single phase it's 70.8 amps. If it runs on 2 wires plus ground, take the voltage rating of the equipment and divide that into the watts to get amps. At 480v 3 phase it's 25.8 amps. At 208v 3 phase it's 47.2 amps. <<>> There are zero amps in 14 kW. A voltage needs to be stated. I = W/E, Amps = Watts/Volts.
What will be the full load current of single phase 5Kva ups?
Assuming single phase voltage 220 Volts AC, the maximum current would be approximately 25 amps.
What is 7kva in amps?
In a standard 3 phase system in North America, 7kVa would be equivalent to 19.5 amps on each phase. The equation is: 7kva*1000/208v/1.73=19.45 amps (3 phase)
Do I need more then 70 kVA 3 phase power supply for a 4 sunbeds in a tanning salon?
You don't need three-phase power; tanning beds run on single-phase. You've got enough amps.
How many amps 50 hp 240 3 phase?
106 amps
What is conversion of 4.6kva to kw?
Single-phase, 2.5 amps; three-phase 1.443 amps.
How different is the horsepower used by an air conditioner unit if it runs on either single phase or three phase ac?
There is no difference in horsepower. The manufacturer builds the air conditioner. Engineers calculate and tell the manufacturer how much power is going to be required to make it operate. Smaller units will probably use lower voltage with lower horsepower to operate efficiently. The bigger the unit will take higher horsepower to operate. There comes a point when single phase, low voltage use will not work due to the unavailability of high horsepower, low voltage motors. At this point three phase systems are used with higher voltages to operate the motors. Examples of a 10 HP motor at different voltages. Single phase - 115 volts 100 amps, 230 volts 50 amps. Three phase same HP - 200 volts 32.2, 230 volts 28, 460 volts 14 and 575 volts 11 amps. As you can see if the air conditioner needs a 10 HP motor at single phase 115 volts, a feeder supply of 100 amps would be needed. This compared to the same air conditioner using a three phase 575 volt system which draws 11 amps.
What amperage will a range with a rating of 12.9 kw draw?
This depends on what voltage the range is rated for and if it is single phase or three phase. At 220 volts single phase it is about 60 amps, 240 v single phase , 53 amps and at 480 v three phase about 15 amps.
How many amperes for 3 phase 220v 5 tonner?
50 Amps Single Phase 20 Amps Three Phase
What is the amperage of a 20 HP 240v single phase motor?
Typically single phase motors go up to 10hp. Wouldn't be very efficient at about 100 amps. A 20hp 3 phase motor at 230v pulls 52 amps. The 10hp single phase 230v pulls 50 amps.
How much breaker load Amps required for 31 kw?
Impossible to say without more details. It depends entirely on the voltage of the supply and whether it's single-phase or three-phase.
How many locked rotor amps does a dual phase 4 ton air conditioner pull?

What is the standard entrance phase and amp to a house?
In the U.S. single phase at 200 amps is average.
How many amps does a 2000 watt heater draw at 240 volts on each line?
For a single phase circuit, the equation you are looking for is I = W/E. Amps = Watts/Volts.
What is the demand load in amps for a range with a 2.4kW single phase at 220V?
That load would be 10.9 amps.
How many amps will a 240 volt single phase 15 kva generator supply?
62.5 amps
What is max single phase hp as per nec?
The maximum single phase HP motor listed in the CEC is 10 HP. At 115 volts 100 amps and 230 volts 50 amps.
