∙ 11y ago1 ton of air-con is defined as 3577 watts
Therefore 20 tons is 71.5 kW. On a 240 v 3-ph system the current for that is 100 amps, assuming a 240 v line-to-neutral voltage, equivalent to a phase-to-phase voltage of 415 v.

∙ 9y agoTo do the proper electrical sizing for an air conditioner connection, watts are not needed. Watts are the product of amps times volts. The voltage needs to be stated for the correct insulation rating and the amperage needs to be stated to select the proper wire size.

∙ 16y agoConvert tons to watts and divide by the supply voltage. One ton of A/C is 822 watts, so 120 tons is 450 amps at 220 volts.

∙ 13y agoIt depends on the type of it and what kind of house you live in, for example if you live in an apartment, it would cost you less. That's cuz of the air conditioner! <3 you question.

∙ 12y agoIt depends on the EER (Energy Efficiency Ratio), which you did not provide. Please restate the question.

∙ 9y ago120 tons is a big system drawing 500-600 kilowatts, and it might be supplied at medium voltage (three-phase, more than 1000 volts), so the current cannot be estimated without more details.

50 Amps Single Phase 20 Amps Three Phase
The formula you are looking for is I = W/E. Amps = Watts/Volts.
It depends on how many amps it was designed for. A 12.5kV/600v 10kVA 3 phase transformer can handle ~.5 amps on the primary and ~10A on the secondary. A 600/120V 10kVA 3 phase transformer can handle ~10A on the primary and ~50 on the secondary.
The answer is that it depends upon the a. efficiency (to determine its input power). b. supply voltage. c. nature of the supply (single-phase, three-phase, d.c., etc.)
22 kw motor how much takes ampares with load
In a three-phase 225 amp panelboard, each phase will carry 225 amps. This means that the total current flowing through the panelboard is distributed evenly across the three phases, allowing for a maximum of 225 amps on each phase at a time.

To calculate the amperage drawn by the heater, you can use the formula: Amperage (A) = Power (W) / (Voltage (V) * Square root of 3). In this case, the amperage drawn will be approximately 5.8 Amps.
62.5 amps
On a 50 amp 3 phase connector, you can pull 50 amps per leg. This means that each of the three phases can carry up to 50 amps individually, resulting in a total capacity of 50 amps per leg.
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.
UK Mains is 230V therefore 6 KW is 6000/230 = 26 Amps. 3 phase is slightly different....... 6000/400V = 15 Amps/root 3 = 8.67 Amps per phase.
In a three phase 225 amp panel, there would be a total of 225 amps available for each phase, making it a total of 675 amps for all three phases combined. This means that you could have up to 225 amps of current flowing through each phase simultaneously.
UK Mains is 230V therefore 6 KW is 6000/230 = 26 Amps. 3 phase is slightly different....... 6000/400V = 15 Amps/root 3 = 8.67 Amps per phase.
For a single phase circuit, the equation you are looking for is I = W/E. Amps = Watts/Volts.
