I've seen cracked SE from age after 10-30 years not 3.
We have a standard 200amp overhead service. Comes into meter pan and from the meter pan we ran a 6' of 2"pvc into house to service entrance rated transfer switch. Out of switch we ran SER cable to panel. Inspector said we can't run that far in house as per code. I know if it was SEU cable we have to be the nearest point of entry in home.
