    Starting & Locked rotor amps

    Many people in the HVAC business say and think these have the same meaning, but I am here to tell you they do not. Can anyone tell me why they do not? I already know the answer, but want to see how many of you out there that also know why.

    Why do you ask so many questions? 17 post all in 1 day and all questions. You sound like a little 4 year old kid that doesn't know how .

    How many times must one fix something before it is fixed?

    I joined this forum to learn so I"ll bite on this one. I know the difference between locked rotor amps & full load amps. but I don't know the difference between starting amps & locked rotor amps. So what's the difference?

    One value is the normal starting current for a system that works properly, and the other should never happen unless a failure has occurred that prevents the rotor from turning.

    Well now I am confused. I think you are saying starting amps are normal but locked rotor amps are bad. Everything I've read indicates that locked rotor amps result at normal start up simply because the rotor is not turning & does not generate counter EMF so current flow is high. Is there really a difference?
