Exam Details

The Iowa Disconnecting and Reconnecting Existing Air Conditioning and Refrigeration Systems examination is associated with the Iowa Electrical Examining Board's Special Electrician licensing program.

The current examination contains 50 scored questions with 120 minutes allowed for the scored portion. Candidates qualifying through examination must meet Iowa's current passing standard of 70%.

The examination also includes 5 non-scored questions, with additional testing time provided for those items. Non-scored questions are used for examination-development purposes and do not affect the candidate's final score.

Exam preparation should cover electrical subjects that directly relate to disconnecting and reconnecting air-conditioning and refrigeration equipment, including:

• General Electrical Knowledge
• Feeders and Branch Circuits
• Grounding and Bonding
• Raceways and Enclosures
• Conductors
• Motors and Controls
• Special Occupancies

Air-conditioning and refrigeration equipment frequently combines motors, compressors, controllers, disconnects, overcurrent protection, equipment grounding, flexible wiring methods, outdoor equipment, and manufacturer nameplate information. Candidates should be comfortable applying general NEC requirements together with equipment-specific provisions.

Open Book Test

The Iowa Disconnecting and Reconnecting Existing Air Conditioning and Refrigeration Systems examination is an open book test using approved reference material.

Iowa currently uses the 2023 National Electrical Code for electrical examinations. The National Electrical Code Handbook, 2023 included with The 1 Package provides the NEC text together with explanatory material that supports study of electrical installations and code navigation.

An open-book examination still requires strong preparation. Candidates must be able to identify the electrical issue being tested, determine the likely NEC article or table, and locate the appropriate requirement within the available testing time.

The highlighted and tabbed NEC Handbook supports this process by helping candidates build familiarity with frequently used sections involving conductors, grounding, overcurrent protection, motors, disconnecting means, wiring methods, and air-conditioning and refrigeration equipment.

Ugly's Electrical References is included as a study resource for electrical formulas, conductor information, motor information, voltage drop, grounding, transformers, conversions, and practical calculations. It should be used to strengthen electrical knowledge during preparation rather than as a substitute for learning to navigate the NEC.

9. Complete the remaining licensing requirements. Submit any remaining documentation required by the Iowa Electrical Examining Board.
10. Address separate business and contractor requirements. Candidates who plan to operate a business must also consider the licensing and registration requirements that apply to the services their company will offer.

Application Service is included with The 1 Package to provide support with organizing and working through the applicable Iowa licensing application process.

State Requirements

Iowa administrative rules identify Disconnecting and Reconnecting Existing Air Conditioning and Refrigeration Systems as an endorsement available under the Special Electrician license.

The endorsement may be issued when requested by an applicant who has either passed a supervised examination approved by the Iowa Electrical Examining Board or completed two years of documented experience in disconnecting and reconnecting existing air-conditioning and refrigeration systems.

This specialty credential is narrower in scope than a general Master Electrician or Journeyman Electrician license. It is intended for the specific electrical work covered by the endorsement and should not be treated as authorization to perform unrestricted electrical installations.

Iowa also provides an important licensing exception for certain professionals already licensed through the Iowa Plumbing and Mechanical Systems Board. Individuals holding qualifying Master HVAC/Refrigeration, Journeyperson HVAC/Refrigeration, Master Mechanical, or Journeyperson Mechanical credentials may perform the covered disconnect/reconnect work without obtaining a separate Electrical Examining Board license solely for that work.

Applicants pursuing an electrical credential can use Iowa's online Electrical Licensing System to create an account, submit a new application, complete the required checklist, and apply by examination or another applicable qualification pathway.

Business licensing and registration requirements depend on the type of work the company performs. Iowa separately regulates electrical contractors and plumbing/mechanical contractors, so candidates should establish the business structure and contractor credentials that correspond to the actual services offered.

Iowa currently uses the 2023 National Electrical Code. Statewide electrical installations are subject to the 2023 NEC requirements currently in effect under Iowa law.

  Included Book: A highlighted and tabbed rental study reference covering electrical formulas, Ohm's law, conductor information, voltage drop, grounding, motors, transformers, conversions, and other practical electrical information useful during exam preparation.

Exam Room Approved Books

• National Electrical Code Handbook, 2023
  The NEC Handbook included with The 1 Package is the primary approved code reference provided with this package for preparation and exam use. Its highlighted and tabbed format is designed to support efficient navigation of important electrical subjects.

Ugly's Electrical References is included as a preparation resource and should be used for study, formulas, and calculation review rather than as the primary exam-room code reference.

Test Information and Study Materials

General Electrical Knowledge should provide the foundation for preparation. Candidates should review voltage, current, resistance, electrical power, Ohm's law, conductor characteristics, terminology, and basic electrical calculations.

Ugly's Electrical References can help reinforce formulas and commonly used electrical information. Candidates should practice enough calculations that they understand the process rather than simply locating a formula.

Feeders and Branch Circuits are important because air-conditioning and refrigeration equipment must receive an electrical supply that complies with applicable NEC requirements. Review circuit ratings, conductor selection, overcurrent protection, disconnects, and the relationship between equipment ratings and the circuit supplying the equipment.

Grounding and Bonding should receive focused study. Candidates should understand equipment grounding conductors, bonding, fault-current paths, grounding connections, and the role grounding and bonding play in electrical safety.

Raceways and Enclosures are particularly relevant because air-conditioning and refrigeration equipment may be located outdoors, on rooftops, in mechanical spaces, or in other environments where moisture, weather, vibration, and physical protection affect the installation.

Study flexible wiring methods, raceways, fittings, boxes, enclosures, support requirements, wet-location provisions, and protection from physical damage.

Conductors are another major area of preparation. Review conductor ampacity, insulation types, temperature limitations, conductor identification, equipment grounding conductors, and the relationship between conductor sizing and equipment ratings.

Air-conditioning equipment frequently includes nameplate information such as minimum circuit ampacity and maximum overcurrent protection. Candidates should understand how equipment-specific NEC rules affect conductor and overcurrent-device selection.

Motors and Controls are especially important because compressors, condenser fans, evaporator fans, blowers, pumps, and other HVAC/refrigeration equipment frequently incorporate motors and control systems.

Review motor conductors, overload protection, branch-circuit short-circuit and ground-fault protection, controllers, and disconnecting means. These requirements perform different functions, and candidates should understand which rule applies to each part of the installation.

The NEC provisions for air-conditioning and refrigerating equipment deserve dedicated study. Candidates should know how those requirements interact with general motor provisions and recognize when equipment-specific rules apply.

Special Occupancies may also affect electrical installations. Equipment located in a specialized environment can be subject to additional NEC requirements because of the use or characteristics of the location.

A practical study method is to work through equipment scenarios. Consider an existing outdoor condensing unit and identify the circuit conductors, equipment grounding conductor, disconnecting means, overcurrent protection, wiring method, motor-related requirements, and relevant nameplate information.

Then practice locating each requirement in the NEC Handbook. This approach connects Code navigation with the type of equipment work addressed by the Iowa specialty endorsement.

The examination provides 120 minutes for 50 scored questions, so efficient reference use matters. Candidates who become familiar with the organization of the NEC can devote more examination time to calculations and questions requiring multiple Code provisions.

When reviewing missed practice questions, identify the source of the mistake. It may involve selecting the wrong NEC article, overlooking equipment nameplate information, confusing overload protection with branch-circuit protection, misapplying conductor requirements, or missing an equipment-specific rule.

The included 1 year of course access provides an extended preparation period for reviewing electrical topics, practicing calculations, strengthening NEC navigation, and revisiting difficult areas.

Please allow up to 15 business days for The 1 Package book orders.
