ECN Forum Forums General Topics of the Trade General Discussion Area Does 1 ton of cooling equal 7 amps?

12000= a ton BTU's It's hard to convert into motor amperage because most motor are 60% - 70% efficient.

Single phase A/C units need about 1 HP per Ton. One Horse Power is 746 watts.

So, 746 watts x 160% eff = 1230.9 watts needed to produce 1 ton of A/C.

1230.9 / 120 volts = 10.5 amps for the motor
