The electrical lateral (sometimes called service
lateral) is the power wire that travels from the city
transformer to the exterior service panel of the house.
Depending on your situation, the service will come
from an overhead line, or through an underground electrical
conduit (some jurisdictions don't require conduit).
If the service is coming from underground the contractor
is responsible to dig the trench and install the conduit
in accordance with the electrical company specifications
and the National Electrical Code (NEC).
Once the electrical rough in is complete it is now
time to get the permanent power installed. During
the rough-in process the electrician must install
one finished GFCI receptacle and one breaker. This
will allow the electrical company to install permanent
power and to remove the temporary power pole leaving
power access for the subs.

The gas lateral is the pipe that connects
the gas from the main line to the house. The gas utility
company will install the meter and hook up the gas
line from the street to the house. Prior to installing
the gas lateral the gas company will want to make
sure that the following conditions are met: 1. The
gas line has been inspected and pressure tested; 2.
The furnace is installed and ready to run; 3. Schedule
the hook-up with your local gas company, which might
take a few weeks depending on schedules and work load.
To install the gas lateral the gas company locates
the line in the street and then cuts the asphalt and
digs until it locates the line. They tap into that
line and run the lateral line to the house. The size
of the pipe in the house and the meter size are determined
by the number of gas appliances installed.
Getting the gas and electrical hooked into the house
is important during the cold months of the year. During
the cold months drywall, painting and floor coverings
can't be completed without heat. Temporary heating
is an option but can be very expensive.
Contact the utility companies a few weeks before you
need to schedule gas and electrical laterals to get
an idea of their schedule. Also determine who will
pressure test the gas system.
