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
