13.1 Certificates of Competency, Specialty Scopes & Renewal

Key Takeaways

  • Under RCW 19.28.161(1), no one may engage in the electrical construction trade without a valid master, journey level, master specialty, or specialty certificate of competency, unless working as a supervised trainee.
  • WAC 296-46B-920(1) says the 01 general certificate covers all phases and all types of electrical and telecommunications installations, plus minor plumbing allowed by RCW 18.106.150.
  • The 02 residential specialty covers one- and two-family dwellings and Type III, IV, or V multifamily dwellings of not more than six stories above grade (WAC 296-46B-920(2)(a)).
  • Electrician certificates are renewed every three years on or before the holder's birthday; renewal more than 90 days after expiration requires passing the exam again (RCW 19.28.211; WAC 296-46B-940).
  • Renewal requires 24 hours of approved continuing education, including at least 8 hours on changes in the currently adopted NEC and 4 hours on RCW 19.28 and WAC 296-46B (WAC 296-46B-970).

Why this section matters

The Washington Codes section has 17 questions, and at least 70% (12 correct) is required. Many of those questions ask who may do a job, which certificate covers it, and what happens when a certificate lapses. The answers are in two places you are allowed to bring into the test: RCW 19.28 (the statute) and WAC 296-46B (L&I's rules). Tab both.

The certificate requirement

RCW 19.28.161(1) makes it unlawful to engage in the electrical construction trade without one of four certificates of competency: master journey level, journey level, master specialty, or specialty. The only other route is an electrical training certificate, which lets a trainee learn the trade under supervision in the proper ratio (Section 13.2).

WAC 296-46B-940(3) adds day-to-day rules that show up as exam questions:

  • The certificate must be worn and visibly displayed on the front of the upper body. It may be worn inside the outer layer only when protective clothing (rain gear, arc-flash or welding gear) is required, or when working in an attic or crawl space or operating equipment where wearing it would be unsafe. A cold-weather jacket is not protective clothing.
  • The electrician must also carry government-issued photo identification and show it when an inspector asks.
  • A certified electrician must not display a training certificate while working as an electrician.
  • A supervising electrician's certificate must be appropriate for the work the trainee is doing.

The 01 general journey level scope

WAC 296-46B-920(1): the general electrical (01) license or certificate "encompasses all phases and all types of electrical and telecommunications installations," plus the minor plumbing allowed by RCW 18.106.150 (for example, like-in-kind replacement of an appliance or an appliance part such as a water heater thermostat). An 01 electrician may therefore do the work of every specialty.

The 14 specialties (WAC 296-46B-940(4) and -920(2))

L&I groups the specialties by the experience needed to test for them.

CodeSpecialtyHours to testScope highlights (WAC 296-46B-920)

Two traps:

  1. There is no "telecommunications electrician" certificate. Code (09) is a telecommunications contractor and administrator category (WAC 296-46B-920(2)(m)). RCW 19.28.261(4) says the certification statutes do not apply to installing or maintaining telephone, telegraph, radio, or television wires and equipment.
  2. Specialties must stay in scope. Working outside the scope of a certificate is a civil infraction: $250 for a first offense and $500 after that (WAC 296-46B-915(3)(b)).

From journey level to master electrician

A master journey level electrician can do the work and be designated as an electrical contractor's master electrician (the administrator role). RCW 19.28.191(1)(a) requires that the applicant has held a valid journey level certificate for four years before taking the master exam. The master exam is not waived. The PSI bulletin lists three sections for the 01 master exam: 80 NEC and theory questions (4 hours), 20 Washington codes questions (1 hour), and 10 major load calculation questions (2 hours).

Certificate term and renewal

RuleSourceRequirement
Original certificate termWAC 296-46B-940(6)Expires on your birthday at least 2 and not more than 3 years after issue (L&I: 25 to 36 months)
Renewal cycleRCW 19.28.211(1)Every three years, on or before the holder's birthday
Earliest renewalWAC 296-46B-940(7)Not more than 90 days before expiration
Late renewalWAC 296-46B-940(8)Allowed within 90 days after expiration with the late fee (the current WAC 296-46B-909 table doubles the fee)
More than 90 days lateWAC 296-46B-940(9)Must pass the competency exam again
Continuing education not finishedWAC 296-46B-940(11)You may pay on time, but the certificate goes inactive until L&I validates the hours

Continuing education (WAC 296-46B-970)

To renew, an electrician must complete at least 8 hours of approved continuing education for each year of the prior certification period. Any part of a year counts as a full year, so a normal three-year cycle needs 24 hours:

  • at least 8 hours on changes in the currently adopted NEC;
  • 4 hours on RCW 19.28 and WAC 296-46B;
  • the remaining hours from L&I's approved course lists.

You cannot get credit twice for the same class. Basic trainee classes and electrician continuing education are separate lists: a class used for a trainee renewal cannot also count as electrician CE.

Reciprocity with Oregon

Washington has a reciprocal agreement with Oregon (WAC 296-46B-940(18)-(20); L&I).

  • Oregon to Washington: Oregon general journeyman (J) holders who earned the license after an 8,000-hour apprenticeship with at least 576 classroom hours and an Oregon exam, or Oregon general supervising (S) holders licensed by exam, may apply for a reciprocal 01 certificate on form F500-148-000.
  • Washington to Oregon: a Washington 01 certificate earned by passing a Washington exam after an approved apprenticeship, or a Washington master 01 certificate, can qualify for Oregon's reciprocal J license.
  • Disqualifier: anyone who has taken and failed the Washington exam for that certificate within the past two years is not eligible (WAC 296-46B-940(20)(d)).

Exam strategy

When a question describes a worker, first decide which certificate is needed, then whether that certificate is current, displayed, and being used within its scope. Most "who may do this?" questions are answered by WAC 296-46B-920 (scope) or -940 (certificate rules).
