Hi,
Is it not allowable to use an unisulated neutral in the portion of the sec's that are overhead or undeground?

I have a 200A 120/240 VAC Main Panel mounted on a pole..the feeder from the 200A main to the house is a 4/0 3 COND AL URD...2 insulated and one bare conductor (neut). w/ground rod at house..As far as I know this is a legal installation isn't it?

an insulated neutral is only required past the first OCPD EXCEPT where feed from a separate location like another building or pole?

i am getting old...so my memory is not working as good as it used to..

Thanks for any replies
