Chapter 2

Selecting a meter base/socket location

When choosing your meter base/socket location, be sure to consider the types of terrain
where your service line will be buried. Since PSE is responsible for repairing your service
line if it fails, the path you select is subject to being dug up. Therefore, we recommend
that the service line route be accessible for repairs and excavation.
NOTE: Refer to the general requirements section in Chapter 5, Metering Installation,
when selecting a location for your electric meter base and socket.

Multiple If a residential class customer installs a bus gutter or meter-pack enclosure to set
metered two meters (one meter for the house, the other for the shop, barn, garage, etc.) on
services a single piece of property being billed to the same individual, PSE will run a single
service line at the customer’s request. However, the single line must accommodate
the kW load and limit the voltage drop and voltage flicker to within PSE’s standards.
NOTE: PSE will not run a single service line to a bus gutter or meter-pack that
serves multiple residential class customers residing on differing properties with
separate legal ownership.

Service line trenches
This section refers to the illustrations found in the Electric Underground Service
Installation Requirements handout available at pse.com/customerconstruction.

Trench The routing of a customer-provided trench must maintain a minimum of 5 feet from
routing/ septic tanks and a minimum of 10 feet from drain fields.
clearances

Trench and PSE will allow customer-owned facilities within the service line trench if the following
backfill minimum horizontal clearances from PSE facilities are maintained:
requirements • 18 inches minimum for customer-owned tight-line sewer (not tile), storm drain lines,
roof drain lines, natural gas line, propane gas line, fuel oil line, and water mains up
to 6 inches.
• 12 inches minimum for water services, irrigation pipes, lighting, security and electric
supply circuits, closed-system roof drains/storm drains (not French drains), and
culverts.
NOTE: The Electric Underground Service Installation Requirements handout illustrates
the service trench requirements in detail.
Customer- If your service line will be crossing under any permanent structure (driveways, sidewalks,
installed decks, patios, rockeries, retaining walls, or through your backyard), you are required to
service line provide and install conduit under those obstructions.
conduit You are required to provide an electrical service line conduit for services 100-feet long or
less. However, PSE recommends the use of conduit for all services.
