I'm putting in a new service 60 amp with 200 amp. I have meter box steel 2" riser and weather head.can I use pvc conduit out of bottom of meter box 2ft and then into house over to new 200 amp breaker panel? I'm told 02 wire is the correct size? Because of the pvc do I need to run a ground wire from the steel riser to the new breaker panel? I know I need a ground rod and ground going to water entrance line.
