Our POCO requires metallic conduit for a service entrance to the meter. It does not allow a two way feed (as you would have on a overhead meter pole) in the same conduit, so many customers have the service coming into the meter in metallic tubing and the exiting wire going back up the pole in a seperate PVC conduit. We are having an argument on if PVC conduit is permissible for this purpose. If there is applicable code, please list the sections. Thanks.
