Are these breakers adjustable if not may need new as this one may be weak. This problem just started the last time genset was used. The only other possibility is corrosion on the voltage phase switch.

There is a space at the top of the main lugs in the back (about an inch wide). This is the #1 entry point for mice! This must be closed to ensure mice do not take up residence in the distribution box. This is the #1 MOST COMMON source of electrical problems in that box.
