Motor Overloads / Maintenance Testing Frequency and Standards

Motor Overloads / Maintenance Testing Frequency and Standards

Motor Overloads / Maintenance Testing Frequency and Standards

(OP)
Have seen this issue ( motor O/L testing ) generally discussed in past threads, but no detailed info on frequency and what standards (NEC, IEC, etc.) apply.

Could you advise where I might find IEEE / NEC / IEC, or other standards covering O/L testing and/or calibration.

We have Motor Control Center equipment operating in Europe which has been inspected by local HSE agency, and found to be lacking due to lack of testing on a frequency sufficient to assure safe and effective operation. So I would conclude IEC has some governing standard.

I would appreciate any information you may be able to share.
