When to Choose to install a discontinuous conduit system for your electrical service if:
choose • Your electrical service length is 101 feet or longer.
discontinuous
conduit • The sum total of the degrees of bends in the conduit run (including the bend
required at the bottom of the meter base riser) exceeds 180° requiring additional
work pits for cable pulling.
• The elevation at the location of available power is greater than the elevation
of your meter socket (i.e., your meter socket is downhill from the location of
available power).
A table for selecting the required conduit size in a continuous conduit system is
provided in the Electric Underground Service Installation Requirements handout.
