Sizing

Correct sizing is very important to assure correct machinery operation. General sizing is as follows:

 

1x Hp for easy loads

1.5x Hp for medium loads

2x Hp for medium hard and Cnc loads

3x Hp for hard loads

You can call or e-mail for correct sizing help for your machinery.

 

For resistive loads such as welders, lights, ovens, dryers or anything  with a heating or lighting element use one of these two formulas:

1)Take the Fla (full load amps) and divide by 2.8 then multiply that by 1.5 to get the required Hp converter needed.

2) The second way is to take the KW rating and multiply by 1.34 or divide by .75 then multiply  that by 1.5 to get the required Hp converter needed.
