Outbuildings

An outbuilding is a stand-alone structure that is located on residential property and is
not a living space. Typical outbuildings are barns, pump houses, garages, shops, and
storage sheds.

Service line An underground service line to an outbuilding is installed by the customer or PSE,
installation depending upon the intended use of the outbuilding (see Table 6).
responsibilities If you want PSE to install a separate service to your outbuilding, refer to the Service
for outbuildings Installation Responsibilities section at the beginning of this chapter.

NOTE: Installation costs and billing rates are different for each type of primary
use of outbuildings. Contact your CCS Representative at 1-888-321-7779 for
more information.

Cost for service

Charges vary depending on the location of existing electrical facilities, the type of service
you are requesting, and the distance to run service from our facilities to your home.
Contact CCS at 1-888-321-7779 to determine the cost for service.

Power quality, voltage flicker

In your Application for Service, PSE requires the locked rotor starting currents for
the largest single-phase and three-phase motors that draw in-rush current. After we
determine the size of transformer required to serve the new load of the facility, we will
calculate the percent voltage flicker (from the motor’s starting current) at the point of
service and provide that number to you.
If this voltage dip exceeds PSE’s limits based on facility type, the transformer size must
be increased to compensate for this. You will be responsible for the difference in cost of
the larger transformer, or you will need to install sufficient controls to bring flicker back
within PSE’s limits.
NOTE: We will size PSE’s facilities to provide a level of voltage flicker that is normally
acceptable to customers. If you need to be served with a higher quality of service,
contact your CCS Representative.
