Yes, and they are based on 746w per HP with a locked-rotor.
Rich, your are probably right about this, but I was giving the benefit of
the doubt by saying "at start up" instead of a locked rotor condition. There
is a table of locked rotor currents in my NEC book for all values of HP motors
up to about 100 HP. BIG difference in that value and running state current.
But, I am sure many are fooled by such ratings when they shop at the HD
stores. Ratings are funny things, Like compressors for example, they are
rated
in CFM, but everybody rates them at a different PSI rating, you have to be
CAREFUL when making comparisons. Lou
