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

1 Ton of cooling is output.
BTU/HR is output.
746W/HP is also output.

Amps is input.

If you don't know the efficiency and the power factor then you can't figure out the input.

For a more conservative rule of thumb I use 1000W/HP to estimate input.
