Abstract:
A method for connecting a primary cable or conduit extending through a gas main pipeline into a building, via a service line connecting the gas main pipeline into the building, comprising the steps of:closing off the service line from the main pipeline at a first location; purging gas from the service line downstream from the first location; installing first and second cable fittings into the service line after purging the gas from the service line; connecting a branch line cable to the primary cable; routing the branch line cable through the first fitting, into the service line; routing the branch line cable through the service line to the second fitting; routing the branch line cable through the second fitting and out of the service line; routing the branch line cable from the second fitting into the building; sealing the first fitting and the second fitting around the branch line cable, to prevent gas leakage at the first and second fittings; and re-opening up the service line to the main pipeline.
