We have a Generac 14kv at home and I just found out the other day that there had been a fault and it had not run its weekly test since May. Apparently when it starts it surges and that caused an over voltage. I just happened to check the log when I was walking by it the other day and when I started it up manually it cranked for quite a while before starting. The repair tech said it's not that uncommon and a manual start will clear the fault. If we had lost power last week I'm not sure the generator would have started. Just something to be aware of.
