Washington Residential Administrator Book Package

Prepare for the Washington Residential Electrical Administrator examination with a focused book package built around the three core references used for Washington electrical licensing and administrator exams. This package includes the Revised Code of Washington (RCW) Chapter 19.28, Washington Administrative Code (WAC) Chapter 296-46B, and the National Electrical Code, NEC, 2020 Edition.

The Washington Residential Electrical Administrator credential is associated with the state's 02 Residential specialty. Candidates pursuing this administrator certification should understand residential electrical installation requirements as well as the Washington laws and rules governing electrical contractors, administrator responsibilities, permits, inspections, specialty scope, certification, and compliance.

Washington electrical administrator examinations are open book. Candidates may use approved reference materials during testing, making familiarity with the NEC, RCW, and WAC an important part of preparation. The ability to recognize which reference applies to a question and locate the controlling provision efficiently can be just as important as remembering individual electrical rules.

The Residential Administrator role is different from electrician certification. Electrical administrators are responsible for helping ensure electrical contractors comply with Washington electrical laws, rules, and regulations. Administrator certification alone does not authorize a person to perform electrical installation work with the tools of the trade. Anyone performing electrical work must also hold the appropriate electrician certification and work within Washington contractor requirements.

This package helps candidates prepare for both sides of the Residential Administrator examination: residential electrical code knowledge and Washington-specific administrative requirements. The 2020 NEC provides national electrical installation rules, while RCW Chapter 19.28 and WAC Chapter 296-46B establish the Washington legal and regulatory framework governing the electrical trade.

What You Get

• Revised Code of Washington (RCW) Chapter 19.28
  Washington's electrical law covering electrical contractors, electricians, administrators, master electricians, electrical installations, licensing, certification, enforcement, responsibilities, and other statutory requirements governing electrical work in the state.
• Washington Administrative Code (WAC) Chapter 296-46B
  Washington's detailed electrical safety, administration, licensing, examination, inspection, permit, certification, contractor, and installation rules. This reference also contains the scope of work for Washington electrical specialty classifications, including the 02 Residential specialty.
• National Electrical Code, NEC, 2020 Edition
  The NEC edition currently identified by Washington Labor & Industries for electrical licensing examinations. It provides the national electrical requirements that apply to residential wiring, services, feeders, branch circuits, grounding and bonding, overcurrent protection, wiring methods, equipment, and other residential installations.

These three references should be studied together. A residential installation question may begin with a general NEC requirement but also involve a Washington-specific rule or specialty limitation contained in WAC 296-46B. Candidates who are comfortable working between the references can approach the open book examination more efficiently.

Exam Details

The Washington Residential Electrical Administrator examination is part of the specialty electrical administrator program administered through the Washington State Department of Labor & Industries and PSI.

• Classification: Residential Electrical Administrator
• Residential Specialty: 02
• Exam Type: Open book
• Testing Provider: PSI
• Passing Score: 70% on each required examination section
• NEC Edition: National Electrical Code, 2020 Edition
• Washington Law Reference: Chapter 19.28 RCW
• Washington Rule Reference: Chapter 296-46B WAC

Washington electrical administrator examinations may consist of multiple sections. All required sections must be successfully completed during the applicable one-year examination period. For administrator candidates, that one-year period begins with the date of the first examination attempt.

If a candidate passes one examination section but does not pass another, the successfully completed section does not need to be repeated during that same examination period. Candidates must follow the applicable waiting periods before retesting failed sections.

Administrator candidates do not need prior examination approval from Labor & Industries before scheduling. Washington permits electrical administrator candidates to schedule directly with PSI because there are no experience prerequisites to sit for an administrator examination.

Open Book Test

The Washington Residential Electrical Administrator examination is an open book test. Washington allows approved reference materials in the testing center under established examination rules.

The 2020 National Electrical Code may be used. Permanent index tabs are permitted, while removable tabs, sticky notes, and handwritten notes are prohibited. Original copyrighted reference books may contain highlighting and underlining when they otherwise comply with testing-center requirements.

Printed copies of RCW Chapter 19.28 and WAC Chapter 296-46B may also be taken into the examination. Washington Labor & Industries instructs candidates to hole-punch printed state laws and rules and place them in a three-ring binder.

Candidates may use a silent, nonprinting, nonprogrammable calculator that is not designed for preprogrammed electrical calculations. Personal computing devices and personal notes are not allowed.

Open book preparation should emphasize navigation speed. Instead of relying on the index for every question, learn the general organization of the NEC. Become familiar with residential branch circuits, services, feeders, grounding and bonding, wiring methods, equipment, dwelling calculations, and other common residential topics.

The same approach should be used with the Washington references. Practice locating rules concerning administrator duties, contractor requirements, specialty scope, permits, inspections, certification, examination procedures, and Washington-specific electrical amendments.

Licensing Steps

Washington electrical administrator certification is administered through the Washington State Department of Labor & Industries. Residential Administrator candidates follow the specialty administrator pathway.

1. Select the Residential Administrator specialty. Candidates seeking to serve as administrator for a residential specialty electrical contractor should prepare for the administrator examination associated with the 02 Residential specialty.
2. Schedule directly with PSI. Electrical administrator candidates do not require prior L&I examination approval and may schedule the applicable exam directly through PSI.
3. Prepare using the approved references. Study the 2020 NEC, RCW Chapter 19.28, and WAC Chapter 296-46B with particular attention to residential installations and Washington administrator responsibilities.
4. Begin the one-year examination period. The one-year administrator examination period begins with the candidate's first examination attempt.
5. Pass every required examination section. Washington requires a score of at least 70% on each examination section.
6. Retest failed sections when necessary. Candidates may retake unsuccessful sections after the applicable waiting period while keeping successfully completed sections during the same examination period.
7. Submit passing score reports. After all required sections are passed, provide the required PSI score reports and certification fee to Washington Labor & Industries.
8. Complete the administrator certification process. Labor & Industries must receive the required materials within 90 days of the last passing score date.
9. Complete contractor assignment when applicable. A certified Residential Administrator who will serve as the designated administrator for a contractor must complete the required assignment process.

When an administrator becomes assigned to an electrical contractor, the administrator accepts responsibility for helping ensure that contractor operations comply with applicable Washington electrical laws and rules.

State Requirements

Washington has a General Electrical Administrator classification and multiple specialty administrator classifications. Residential is one of the recognized specialties and corresponds to the 02 Residential electrical specialty.

There are no experience prerequisites to take an electrical administrator examination. Unlike electrician certification, candidates do not need to document thousands of electrical work hours before scheduling an administrator exam.

However, administrator certification does not authorize the certificate holder to personally perform electrical installation work. A Residential Administrator who wants to perform electrical work must separately hold the appropriate electrician certification and work under an electrical contractor as required by Washington law.

A specialty administrator may be assigned only within the contractor specialty that corresponds to the administrator's certification. A Residential Administrator is therefore associated with the residential specialty contractor scope rather than unrestricted general electrical contracting.

Washington's 02 Residential specialty includes qualifying telecommunications, low-voltage, and line-voltage wiring in one- and two-family dwellings and qualifying multifamily residential construction within the limits established in WAC 296-46B.

The specialty scope can also include qualifying electrical installations associated with residential ancillary structures and systems. Candidates should study the exact WAC scope because specialty limitations are important both for examination purposes and for contractor compliance after certification.

An administrator assigned to an electrical contracting company must also meet Washington assignment requirements and notify Labor & Industries of changes in assignment status within the period established by state rules.
