Service Conduit Size

Service conduit size refers to the size of either the overhead or underground service conduit that feeds the service from the utility pole. For underground service conduit, the size is typically 2 inch PVC conduit. For overhead service conduit, the size is determined by the size of the conductors and by the requirements of the utility. Typical sizes for overhead service conduit are 1¼", 1½", and 2" RMC.
