Washington Pump & Irrigation Master Electrician Book Package

Prepare for the Washington Pump & Irrigation Master Electrician examination with a focused book package built around the primary electrical code, Washington electrical law, and state administrative rules used for the 03 Pump & Irrigation 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.

The Washington Pump & Irrigation Master Electrician certification is a specialty master credential. It is designed for experienced electricians who already hold the Washington 03 Pump & Irrigation specialty electrician certificate and are ready to move into the master-level classification. Preparation requires familiarity with electrical installations associated with pumps, water systems, controls, feeders, services, motors, grounding and bonding, wiring methods, and Washington-specific electrical laws and rules.

Washington electrical examinations are open book. Candidates may bring approved reference materials into the testing center under Labor & Industries examination rules. That makes efficient navigation of the NEC, RCW, and WAC an important part of preparation. Candidates should know which reference applies to a question and how to locate the governing requirement without spending unnecessary time searching.

The Pump & Irrigation specialty is limited to specified electrical work associated with domestic water systems, public water systems, irrigation systems, pumps, pressurization, filtration, treatment equipment, controls, pump houses, and related installations. Because the specialty involves motors, controls, electrical services, feeders, and equipment exposed to demanding operating environments, candidates should be comfortable applying both general NEC rules and specialty-specific Washington requirements.

This package gives candidates the three core references needed to build an organized study routine. The NEC provides national electrical installation requirements, RCW 19.28 establishes Washington electrical law, and WAC 296-46B contains detailed state rules, specialty scopes, certification requirements, inspections, permits, and Washington-specific electrical provisions.

What You Get

  • Revised Code of Washington (RCW) Chapter 19.28
    Washington's electrical law covering electricians, master electricians, electrical contractors, electrical installations, certification, enforcement, responsibilities, and other statutory requirements governing electrical work throughout the state.
  • Washington Administrative Code (WAC) Chapter 296-46B
    Washington's detailed electrical safety, administration, licensing, examination, certification, inspection, permit, and installation rules. This reference also defines the scope of the 03 Pump & Irrigation specialty and other Washington electrical classifications.
  • National Electrical Code, NEC, 2020 Edition
    The NEC edition identified by Washington Labor & Industries for the current examination program. It provides national requirements covering services, feeders, motors, controls, grounding and bonding, overcurrent protection, wiring methods, equipment, special conditions, and other installations relevant to pump and irrigation work.

These references are most effective when studied together. A pump or irrigation installation may involve a general NEC requirement, a Washington state amendment, and a specialty-scope limitation at the same time. Candidates should practice moving between the three books and identifying which requirement controls the situation described in an exam question.

Exam Details

Washington identifies this classification as the 03 Pump & Irrigation Master Electrician. The master examination is divided into two sections: NEC & Theory and Washington Codes.

  • NEC & Theory: Approximately 50 questions
  • Time Allowed for NEC & Theory: 3 hours
  • Washington Codes: Approximately 20 questions
  • Time Allowed for Washington Codes: 1 hour
  • Total Questions: Approximately 70 questions across both sections
  • Total Testing Time: Approximately 4 hours across both sections
  • Passing Score: 70% on each required examination section
  • Exam Type: Open book
  • Testing Provider: PSI
  • NEC Edition: 2020 National Electrical Code

The published examination outline places significant emphasis on grounding and bonding, wiring methods, motors and related equipment, services, overcurrent protection, wiring and protection, electrical equipment, special conditions, and general trade knowledge and theory. The Washington Codes section tests Washington electrical laws and rules contained in RCW 19.28 and WAC 296-46B.

The approximate NEC & Theory distribution includes questions from NEC introduction and general requirements, wiring and protection, services, overcurrent protection, grounding and bonding, wiring methods, electrical equipment, motors, HVAC equipment, generators and transformers, equipment over 600 volts, hazardous locations, special equipment, special conditions, and general trade knowledge and theory.

Open Book Test

The Washington Pump & Irrigation Master Electrician examination is an open book test. Candidates may bring approved reference materials into the testing center under Washington Labor & Industries rules.

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

Printed copies of RCW Chapter 19.28 and WAC Chapter 296-46B are also permitted. Washington requires printed copies of its electrical laws and rules to be hole-punched and placed in a three-ring binder.

Candidates may use a silent, nonprinting, nonprogrammable calculator that complies with testing rules. Calculators designed for preprogrammed electrical calculations are not permitted.

Open book preparation should focus on navigation as well as technical understanding. Candidates should become familiar with the NEC index, article organization, tables, exceptions, definitions, and cross-references. The same practice should be applied to Washington rules so specialty scope, licensing provisions, and state amendments can be located efficiently.

Questions involving motors, disconnects, branch-circuit and feeder conductors, grounding and bonding, overcurrent protection, or services will generally require the NEC. Questions involving the legal scope of the 03 specialty, certification, contractor responsibilities, permits, inspections, or Washington-specific requirements may require RCW 19.28 or WAC 296-46B.

Licensing Steps

Washington Pump & Irrigation Master Electrician certification is administered by the Washington State Department of Labor & Industries. Candidates follow the specialty master electrician pathway.

  1. Hold the 03 Pump & Irrigation electrician certification. Candidates must first be certified by Washington Labor & Industries in the applicable specialty.
  2. Meet the specialty master experience period. Washington requires a specialty master electrician candidate to have held the applicable specialty electrician certificate for at least two years.
  3. Apply for the Master Electrician examination. Submit the required master examination application through Washington Labor & Industries.
  4. Receive examination approval. Candidates should not schedule the examination with PSI until Labor & Industries approves the request.
  5. Prepare for both examination sections. Study the NEC & Theory portion and the Washington Codes portion using the approved references.
  6. Schedule with PSI. After approval, schedule the required examination sections through the authorized testing provider.
  7. Pass each required section. Washington requires a score of at least 70% on each section.
  8. Complete master certification requirements. After successful examination completion, follow Labor & Industries procedures for issuance of the specialty Master Electrician certificate.

When Washington issues the master certificate in the same category, it replaces the existing electrician certificate for that classification. The holder does not carry both an electrician certificate and a master electrician certificate for the same specialty at the same time.

State Requirements

The Pump & Irrigation specialty is identified as 03 under Washington electrical rules. It is one of the state's recognized specialty electrician classifications.

To qualify for the Pump & Irrigation Master Electrician examination, a candidate must have been certified by Washington Labor & Industries in the applicable specialty for at least two years.

The underlying 03 Pump & Irrigation electrician certification requires 4,000 hours of qualifying work experience in the specialty. Washington also requires the applicable basic classroom instruction for candidates pursuing a 4,000-hour specialty examination pathway.

The scope of the 03 specialty is limited to the electrical connection of circuits, feeders, controls, low-voltage systems, related telecommunications, and services supplying specified water-related equipment and systems. These can include domestic water systems, public water systems, pumps, pressurization equipment, filtration systems, treatment equipment, irrigation water pumps, circular irrigation system pumps, pump houses, and associated controls.

Because the scope is specific, candidates should study the exact specialty boundaries in WAC 296-46B. Master-level certification does not convert the 03 specialty into unrestricted general electrical authority. Work must remain within the scope of the specialty unless the individual holds another applicable certification.

Washington master electrician certificates are renewed periodically and continuing education requirements apply. Washington rules also provide specific continuing education treatment for Pump & Irrigation and Domestic Pump certificate holders because the work can overlap with the pumping and plumbing industry.
