Washington B-HVAC/R Restricted Administrator Book Package

Prepare for the Washington HVAC/Refrigeration Restricted Electrical Administrator examination with a focused reference package built around the electrical code, Washington electrical law, and state administrative rules used for the 06B HVAC/Refrigeration Restricted specialty. 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.

Washington officially identifies this electrical specialty as 06B HVAC/Refrigeration Restricted. The administrator examination combines National Electrical Code knowledge, electrical theory, and Washington-specific laws and rules. Candidates should understand both technical HVAC/R electrical requirements and the limitations that determine what work an electrical contractor operating under the 06B specialty may perform.

Electrical administrators play an important compliance role in Washington. An administrator assigned to an electrical contractor accepts responsibility for helping ensure that the contractor complies with applicable Washington electrical laws and rules. Specialty administrators are limited to contractors holding the corresponding specialty classification, so a 06B Administrator works specifically within the HVAC/Refrigeration Restricted specialty.

Washington administrator examinations are open book. Approved reference materials may be brought into the testing center, which makes code-navigation skills an important part of preparation. Candidates should become comfortable determining whether a question belongs in the NEC, RCW Chapter 19.28, or WAC Chapter 296-46B and then locating the controlling provision efficiently.

The 06B classification permits defined HVAC and refrigeration electrical work while imposing specific limits on the primary electrical power connection to the HVAC/refrigeration system. Understanding those boundaries is important for both examination preparation and administrator responsibilities after certification.

This package brings the three central references together for organized study. The NEC provides technical installation standards, RCW Chapter 19.28 establishes Washington electrical law, and WAC Chapter 296-46B contains detailed rules for administrator certification, contractors, specialty scope, examinations, permits, inspections, and electrical installations.

Licensing Steps

Washington electrical administrator certification is administered through the Washington State Department of Labor & Industries. Unlike electrician and Master Electrician candidates, administrator candidates do not need prior L&I approval before registering for the examination.

1. Select the 06B HVAC/Refrigeration Restricted Administrator classification. This specialty administrator credential corresponds to the 06B HVAC/Refrigeration Restricted contractor classification.
2. Register directly with PSI. Washington does not require L&I pre-approval for an electrical administrator candidate to schedule the examination.
3. Prepare for the NEC & Theory section. Study the 2020 NEC with emphasis on overcurrent protection, grounding and bonding, wiring methods, HVAC/R equipment, motors, electrical equipment, hazardous locations, special conditions, and electrical theory.
4. Prepare for Washington Codes. Study RCW Chapter 19.28 and WAC Chapter 296-46B, including administrator responsibilities and the 06B specialty scope.
5. Take all required examination sections. The first examination attempt begins the one-year administrator examination period.
6. Pass each section with at least 70%. Sections passed during the same examination period do not need to be repeated while that examination period remains active.
7. Complete all required sections within one year. Administrator candidates must successfully complete every section within the applicable one-year examination period.
8. Apply for the administrator certificate. After passing all sections, submit the required score reports and certification materials to Washington Labor & Industries.
9. Complete the certification application within 90 days. L&I must receive the required materials within 90 days of the final passing score.

State Requirements

There are no experience prerequisites to take a Washington electrical administrator examination. A candidate does not need to hold an electrician certificate or document a specific number of electrical work hours before testing for the 06B Administrator certificate.

Administrator certification alone does not authorize the certificate holder to work with the tools of the electrical trade or perform electrical installations. A person performing electrical work must separately hold the appropriate Washington electrician certification and work under the applicable contractor requirements.

Washington has general and specialty electrical administrator classifications. A specialty administrator can only be assigned to an electrical contractor holding the corresponding specialty. A 06B HVAC/Refrigeration Restricted Administrator therefore serves a contractor operating within the 06B specialty rather than providing general electrical contracting authority.

The 06B specialty may not perform electrical work where the primary electrical power connection to the HVAC/refrigeration system exceeds 250 volts, single phase, or 120 amperes. This restriction is a defining feature of the classification and is an important subject for candidates to understand.

The specialty may install, repair, replace, and maintain specified HVAC/refrigeration telecommunications and Class 2 low-voltage control wiring and components in residential occupancies. It also permits qualifying HVAC/R telecommunications and Class 2 low-voltage control work in nonresidential occupancies that have no more than three stories on or above grade.

The classification may perform qualifying work on line-voltage components located within HVAC/refrigeration equipment. It may also repair, replace, or maintain internal components of qualifying equipment disconnecting means or controllers when the equipment meets the conditions established by Washington rules.

The 06B specialty may install short sections of raceway to provide physical protection for low-voltage cables. Washington defines limitations on this work so that the protective raceway does not become an unrestricted raceway installation between devices, junction boxes, or other components.

The specialty may also repair, replace, or maintain qualifying line-voltage flexible supply whips that are not more than six feet in length when the work meets the requirements of WAC Chapter 296-46B.

06B generally may not install line-voltage controllers or disconnect switches external to HVAC/refrigeration equipment. Washington rules provide a limited exception involving certain like-in-kind disconnecting means replacements associated with HVAC/R equipment replacement when all stated conditions are met.

Administrator certificates are renewed on a three-year cycle. Washington requires approved continuing education for renewal, including code-update and RCW/WAC content. An administrator assigned to an electrical contractor must also follow Washington requirements regarding changes in assignment status.

Reference Books

• Revised Code of Washington (RCW) Chapter 19.28
  This reference contains Washington electrical statutes governing administrators, contractors, electricians, certification, electrical installations, enforcement, and legal responsibilities. It provides the statutory foundation for the Washington electrical licensing system.
• Washington Administrative Code (WAC) Chapter 296-46B
  This reference contains administrator rules, contractor requirements, examination provisions, permits, inspections, specialty classifications, and the detailed scope and restrictions of 06B HVAC/Refrigeration Restricted work.

Administrator Responsibilities: Review the role of the designated administrator, contractor assignment requirements, examination and certification rules, permits, inspections, and Washington compliance responsibilities.

For open-book preparation, practice deciding which reference applies before opening a book. This can save time and reinforce the difference between NEC technical questions and Washington licensing or scope-of-work questions.

How 1 Exam Prep Helps You Reach Your Goal

1 Exam Prep helps Washington HVAC/R Restricted Administrator candidates organize preparation around the three core references included in this package: the 2020 National Electrical Code, RCW Chapter 19.28, and WAC Chapter 296-46B.

The package supports trade-focused review of overcurrent protection, grounding and bonding, wiring methods, HVAC/R equipment, motors, electrical theory, Washington administrator requirements, and the limits of the 06B specialty.

1 Exam Prep encourages practice-oriented study for the open-book examination. Candidates can strengthen their preparation by identifying the topic of each question, selecting the correct reference, finding the applicable provision, and applying the rule efficiently.

Reference navigation is especially useful for a specialty administrator examination because candidates must understand both technical code requirements and Washington contractor regulations. A technically correct installation still needs to fall within the electrical contractor's authorized specialty scope.

Organized preparation can also help candidates recognize subjects that need more attention. Additional review can then be directed toward grounding, overcurrent protection, motors, wiring methods, electrical theory, or Washington Codes based on individual study needs.

The goal is to combine HVAC/R electrical knowledge with structured code study, Washington regulatory awareness, practical reference navigation, and confidence-building preparation. This Washington B-HVAC/R Restricted Administrator Book Package provides the core references needed to support that study process.
