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.
