Mark Feach asks this question, which concerns the desirability of using capacitor banks with running generators. It has been answered by ABB (Theme - Power):
Question: A client has been requesting that we switch off the capacitor bank on a low voltage panel when the site's generator is in use.
Can you please advise as to whether this is correct and if so, why?
Answer: Most generator manufacturers recommend switching off any power factor correction equipment when running on a generator electrical supply.
The reason for this is to prevent the possibility of having a leading power factor, which can cause generator set failures, or the failure of certain loads to operate properly on a generator set.
