I've read the section about 30 times. I see what you are getting at George. I agree.
I saw a 30 amp disco, DU221RB, rated at 3 HP.
I still have a question though. Is the intent of 440.12(B) [and 430.110(C) for that matter] trying to say 'figure the HP rating twice(using the motor tables), both by the rated current of the motors and by the locked rotor current of the motors; whichever is the highest HP rating figured is the required rating of the disco?
If that's what is suppose to be done, it doesn't say that very well. If I still don't get it--HELP!
Also, can I still use (trust) the equipment current rating or do I have to check the ampere & LR rating of the compressor and blower motors separately?
