To determine the amperage of a 10-ton 3-phase 415 volt air conditioner, we can use the formula:
Amperage = (Power / (Voltage * √3)),
where Power is the power consumption of the air conditioner in watts, Voltage is the line voltage in volts, and √3 represents the square root of 3 (approximately 1.732).
For a 10-ton air conditioner, we need to convert tons to BTUs (British Thermal Units) and then to watts. One ton of cooling capacity is equivalent to 12,000 BTUs per hour. Therefore, a 10-ton air conditioner has a cooling capacity of 120,000 BTUs per hour.
To convert BTUs per hour to watts, we can use the conversion factor: 1 BTU/hr = 0.293071 watts.
So, the power consumption of the 10-ton air conditioner in watts would be:
Power = 120,000 BTU/hr * 0.293071 watts/BTU = 35,168.52 watts.
Now, let's calculate the amperage using the formula:
Amperage = (35,168.52 watts / (415 volts * √3)).
Amperage ≈ 35,168.52 / (415 * 1.732) ≈ 52.5 amperes.
Therefore, a 10-ton 3-phase 415-volt air conditioner would take approximately 52.5 amperes of current.
