2025 Rulemaking - Electric vehicle charging installation
L&I is considering electrical rule changes that would affect requirements for installing electric vehicle supply equipment and electrician and administrator competency examinations. The changes are necessary because of legislation passed earlier this year and to streamline the rules.
The legislation involves Installation of Electric Vehicle Supply Equipment (SSB 5528 implementation). The changes would affect Chapter 296-46B WAC, Electric Safety Standards, Administration, and Installation.
The agency filed a CR-101 Preproposal Statement of Inquiry on Aug. 5.
About the new statutory amendments
Substitute Senate Bill 5528 (SSB 5528) (Chapter 233, 2025 Laws), requires additional certification requirements for electricians performing work on electrical vehicle supply equipment on all public works projects. It takes effect Jan. 1, 2026.
The provisions of the law include:
- People installing electric vehicle supply equipment on all public works as defined in RCW 39.4.010, must be certified by the Electric Vehicle Infrastructure Training Program (EVITP), or a similar nationally recognized training program;
- The EVITP, or similar nationally recognized program, must be open to all general journey level electricians.
- Certification is required only for work on the electrical components during the installation and maintenance of electric vehicle supply equipment.
- The requirements do not apply to:
- certain apprentices when the supervising journey level electrician is certified by a training program, and;
- installation projects under contract as of Jan. 1, 2026.
The Legislature provided L&I authority to adopt rules to implement the requirements.
Electrician and Administrator Competency Examinations
Changes are also being considered to streamline requirements for electrician and administrator competency examinations. The changes under consideration include:
- Requiring individuals to use department-issued unique candidate identification numbers when arranging for administrator competency examinations;
- Increasing the amount of time allowed for testing without having to start a new examination period and retake all sections; and
- Updates, clarifications, housekeeping, and other changes.
