What usually causes a generator to trip or fail on site, and how is it fixed?

Common causes include undersizing relative to motor starting surges, overheating from blocked ventilation or dusty radiators, fuel contamination, or overload from unplanned load additions after initial sizing. Many trip-outs can be resolved on site by checking load against rated capacity and clearing any overload before restarting, while overheating issues need radiator and filter servicing. Persistent tripping usually signals the unit was undersized for the actual site load rather than a fault with the machine itself. Sparkline Group provides technical support to diagnose these issues quickly rather than leaving a site without power for hours. Reviewing the original sizing calculation is often the first step when trip-outs recur.
