What is the starting current of 1.5 ton split AC?

Hence, cooling capacity of 1.5 ton = 5275 W of power. If the supply voltage is around 220 V AC, then the running current will be 1510/220 = 6.9 A. As starting current is usually 2–2.5 times the running current, the starting current of a 1.5 ton 5 star split AC with no gas is estimated to be around 15–20 A.

So, how many amps does it take to run an air conditioner?

Most common voltage ratings for AC units are 115, 125 and 220 volts, and amperage rating can run from 15 to 20 amps. The lower two voltage ratings are common in smaller units, while units with a rating higher than 15,000 BTUs will require a 220-volt circuit.
