Washington A-HVAC/R Administrator Book Package

Prepare for the Washington HVAC/Refrigeration Electrical Administrator examination with a focused book package built around the electrical code, Washington electrical law, and state administrative rules used for the 06A HVAC/Refrigeration 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 identifies HVAC/Refrigeration as electrical specialty classification 06A. A Washington HVAC/R Electrical Administrator is responsible for helping ensure that an electrical contractor operating under the 06A specialty complies with applicable Washington electrical laws, rules, regulations, licensing requirements, and electrical installation standards.

The administrator examination combines technical electrical knowledge with Washington-specific regulatory knowledge. Candidates should be prepared for questions involving HVAC and refrigeration equipment, motors, overcurrent protection, grounding and bonding, wiring methods, electrical equipment, circuits over 600 volts, hazardous locations, special conditions, electrical theory, and Washington electrical laws and rules.

Washington electrical administrator examinations are open book. Candidates may bring approved reference materials into the testing center, making efficient reference navigation a key part of exam preparation. The ability to recognize whether a question belongs in the NEC, RCW Chapter 19.28, or WAC Chapter 296-46B can help candidates use testing time more effectively.

The 06A HVAC/Refrigeration specialty covers defined electrical work associated with heating, ventilation, air-conditioning, and refrigeration systems. Washington rules include specified low-voltage controls, telecommunications, line-voltage components located within HVAC/R equipment, certain controller and disconnect components, limited raceway work, qualifying flexible supply connections, and other electrical work that falls within the specialty scope.

This package gives candidates the three core references used for Washington electrical exam preparation. The NEC provides national technical requirements, RCW Chapter 19.28 establishes Washington electrical law, and WAC Chapter 296-46B contains detailed rules governing administrators, electrical contractors, examinations, specialty classifications, permits, inspections, and electrical installations.

What You Get

• Revised Code of Washington (RCW) Chapter 19.28
  Washington's electrical law covering electrical contractors, administrators, electricians, electrical installations, certification, enforcement, responsibilities, and other statutory requirements governing the electrical trade.
• Washington Administrative Code (WAC) Chapter 296-46B
  Washington's detailed electrical safety, administration, licensing, examination, specialty-scope, contractor, permit, inspection, and installation rules. This reference defines and regulates the 06A HVAC/Refrigeration specialty.

  The NEC edition currently used for the Washington electrical examination program. It provides technical requirements for HVAC equipment, motors, controllers, grounding and bonding, overcurrent protection, wiring methods, conductors, electrical equipment, hazardous locations, and special conditions.

These references should be studied as a coordinated set. A technical question may begin with the NEC, while a Washington rule may define whether the work falls within the 06A specialty or establish additional contractor and administrator requirements.

Exam Details

The Washington 06A HVAC/Refrigeration Electrical Administrator examination is divided into two required sections: NEC & Theory and Washington Codes.

• NEC & Theory: Approximately 40 questions
• Time Allowed for NEC & Theory: 2 hours
• Washington Codes: Approximately 17 questions
• Time Allowed for Washington Codes: 1 hour
• Total Questions: Approximately 57 questions across both sections
• Total Testing Time: Approximately 3 hours across both sections
• Passing Score: 70% or greater on each required examination section
• Exam Type: Open book
• Testing Provider: PSI
• Primary Code Reference: National Electrical Code, NEC, 2020 Edition

The published NEC & Theory examination outline includes approximately one question from NEC Article 90, two from NEC Articles 100 through 110, two from wiring and protection, four from overcurrent protection, four from grounding and bonding, five from wiring methods, four from electrical equipment, seven from motors, HVAC equipment, generators and transformers, one from equipment over 600 volts, one from hazardous locations, one from special equipment, two from special conditions, and approximately six questions involving general trade knowledge and electrical theory.

The Washington Codes section contains approximately 17 questions. Candidates should be familiar with administrator certification, electrical contractor requirements, specialty scope, examination rules, permits, inspections, assignments, and other Washington-specific provisions contained in RCW Chapter 19.28 and WAC Chapter 296-46B.

Open Book Test

The Washington HVAC/R Administrator examination is an open book test. Washington Labor & Industries permits approved reference materials in the testing center under established examination rules.

The 2020 National Electrical Code may be used. Permanent index tabs are allowed, while removable tabs, sticky notes, and handwritten notes are prohibited. Original copyrighted materials may contain highlighting, underlining, and permanent index tabs when they otherwise comply with examination rules.

Printed copies of RCW Chapter 19.28 and WAC Chapter 296-46B may also be brought into the examination. Printed state electrical laws and rules must be hole-punched and placed in a three-ring binder.

Because the NEC & Theory section contains approximately 40 questions in two hours, candidates should practice efficient code lookup. Motors, HVAC equipment, wiring methods, grounding and bonding, overcurrent protection, electrical equipment, and specialty-scope questions should become familiar areas of study.

The Washington references deserve equal attention. Questions involving administrator responsibilities, contractor assignments, permits, inspections, certification, or the limits of the 06A classification may require WAC Chapter 296-46B or RCW Chapter 19.28 rather than the NEC.

Licensing Steps

Washington electrical administrator certification is administered through the Washington State Department of Labor & Industries. Administrator candidates follow a different examination pathway from electricians and master electricians because Washington does not require prior electrical experience or examination approval before an administrator candidate registers with PSI.

1. Select the 06A HVAC/Refrigeration Administrator classification. Candidates who plan to serve as administrator for an HVAC/Refrigeration specialty electrical contractor should take the corresponding 06A administrator examination.
2. Register directly with PSI. Washington electrical administrator candidates do not need prior L&I examination approval before scheduling.
3. Prepare for NEC & Theory. Study the 2020 NEC with particular attention to HVAC/R equipment, motors, controllers, overcurrent protection, grounding and bonding, wiring methods, and electrical equipment.
4. Prepare for Washington Codes. Study RCW Chapter 19.28 and WAC Chapter 296-46B with emphasis on administrators, electrical contractors, specialty scope, permits, inspections, and examinations.
5. Take both required examination sections. The first attempt begins the administrator's one-year examination period.
6. Pass each required section. Washington requires a score of at least 70% on both NEC & Theory and Washington Codes.
7. Retest failed sections when necessary. Failed sections may be retaken after the applicable waiting period without repeating sections already passed during the same one-year examination period.
8. Complete all required sections within one year. All sections must be passed before the examination period expires.
9. Apply for the administrator certificate. Submit the required passing score reports and certification materials to Washington Labor & Industries.
10. Submit the application within 90 days of the last passing score. Washington requires the administrator certification materials to be received within the applicable 90-day period.

State Requirements

Washington recognizes a General Electrical Administrator classification and multiple specialty administrator classifications. HVAC/Refrigeration is specialty classification 06A.

There are no prerequisites to take an electrical administrator examination. A candidate does not need to hold an electrician certificate or document a specified amount of work experience before taking the 06A Administrator exam.

Administrator certification does not authorize a person to perform electrical installation work. Anyone working with the tools of the electrical trade must separately hold the appropriate Washington electrician certification and work under the applicable electrical contractor requirements.

A specialty electrical administrator can only be assigned to an electrical contractor holding the corresponding specialty. A 06A HVAC/Refrigeration Administrator therefore serves within the HVAC/R specialty rather than providing unrestricted general electrical contractor authority.

Washington's HVAC/Refrigeration specialty is not generally limited by voltage, phase, or amperage, but it remains limited to the scope of HVAC/R electrical work established in WAC Chapter 296-46B.

The specialty includes specified Class 2 low-voltage control wiring and telecommunications associated with HVAC/R systems, as well as certain line-voltage components located within HVAC/refrigeration equipment. Washington rules also permit limited work involving controllers, disconnect components, protective raceways, and qualifying flexible supply connections under defined conditions.

The classification does not provide unrestricted authority to install general electrical services, feeders, branch circuits, external controllers, or disconnect switches. Administrator candidates should understand these limits because contractor compliance depends on keeping work within the scope authorized by the contractor's specialty license.

When assigned to an electrical contractor, an administrator accepts responsibility for helping ensure that the contractor complies with applicable Washington electrical laws and rules. This makes knowledge of RCW Chapter 19.28 and WAC Chapter 296-46B important beyond the examination itself.
