i helped install a pole mounted pv system last week.i cant tell specs because i dont know them.the "engineer" was installing the pv
service run from the post mount was 2" liquid tight to ridgid to pvc to the house .pvc, to ridgid to 2"conduit body penetration.
at that point i changed to down to 1" 10"to 18"of flex metal cunduit to inverter. no concentrics.
at this point i know the system is rated for a 60 amp.
from there to pvc to critical power and outside disconnect
disconnect run changes over to 1"liquid tight to no concentrics in the disconnect.
the critical power goes to pvc box with 1"sealtight to the critical power subpanel and then i used 3/4 flex from the pvc box to the main panel for the 60 amp breaker.no concentrics.
all 6 wire including ground.
250 is confusing.
do i need bond bushings?
