Preface

This handbook is your guide to Puget Sound Energy’s (PSE) requirements for new,
altered/modified, or temporary electric service for permanent single-family residential
structures. We have also included additional requirements for electric service to
outbuildings (barns, shops, pump houses, garages, etc.).

What this handbook contains

In this handbook you will find answers to questions such as:
• What are the installation requirements for permanent and temporary underground
and overhead service?
• How do I choose the right service size?
• What are the trenching requirements?
• How do I locate existing underground utilities before I dig?
PSE’s service General boundaries for PSE’s gas and electric service area are available on
availability pse.com/customerconstruction. A Customer Construction Services (CCS)
Representative can help you to determine the closest available service line and can
provide you with cost information for establishing new service.

Codes, permits, and inspections

This handbook should only be used as a guide. It does not cover all possible federal,
state, or local code requirements. It is your responsibility to ensure that your project
complies with the most recent issue of the National Electric Code (NEC) and any
other federal, state, or local codes that may apply.
This handbook shall not be interpreted to conflict with the regulations of the state
of Washington or other regulatory bodies having jurisdiction. PSE’s metering
requirements may be more stringent. Local codes and requirements related to the
planned work should be addressed before any construction begins.
Electrical Once your service equipment is installed, the state of Washington, or the city with
service jurisdiction over your area, requires that your installation pass an electrical inspection
equipment before PSE can energize your system.
inspection NOTE: It is your responsibility to request an electrical inspection.

Electrical inspections for most areas in the PSE service territory are done by
the Washington State Department of Labor and Industries. However, electrical
inspections are performed by city personnel in several jurisdictions. Please
consult pse.com/permitsandinspections for a list of the cities and current
contact information.
