What Does NM-EE98 Stand For?

TL;DR
  • NM-EE98 refers to New Mexico's EE-98 Residential and Commercial Electrical classification, and "Part 1" covers Commercial and Industrial content.
  • Part 1 has 80 questions in 200 minutes, and you need 60 correct (75%) to pass.
  • Domain 1, General Knowledge and Electrical Installation Requirements, carries 13 questions - the largest single domain.
  • The exam is open book, but references must be bound; loose papers and handwritten notes are not allowed.

What NM-EE98 Literally Stands For

NM-EE98 is shorthand for the New Mexico EE-98 Electrical Contractor Exam, administered under the oversight of the New Mexico Regulation and Licensing Department, Construction Industries Division (CID), with PSI acting as the testing provider. "EE-98" is the classification code CID uses for the Residential and Commercial Electrical contractor license, and this site is focused specifically on Part 1 of that exam - the section covering Commercial and Industrial content.

That distinction matters because the letters "EE-98" show up in a handful of unrelated credentialing programs elsewhere. On this site, and in this article, NM-EE98 means exactly one thing: the New Mexico contractor licensing exam pathway administered through PSI for the EE-98 classification. If you're researching what the abbreviation means before you register, that's the definition to anchor to - not a national certification, not a manufacturer program, and not an unrelated professional designation.

Quick Definition: NM-EE98 Part 1 is the Commercial and Industrial exam segment within New Mexico's EE-98 Residential and Commercial Electrical contractor classification, given via PSI's computer-based testing system.

Part 1: Commercial and Industrial Scope

The "Part 1" label is not arbitrary - it identifies which slice of the EE-98 blueprint you're being tested on. Part 1 concentrates on commercial and industrial electrical work: services, feeders, branch circuits, overcurrent protection, grounding and bonding, raceways, hazardous locations, motors, transformers, and the New Mexico-specific code amendments that apply to this kind of installation work. It is deliberately separate from residential-specific content, which lives in Part 2, and from specialty topics, which live in Part 3.

If you want a full breakdown of what each of those ten content areas actually tests, the NM-EE98 Exam Domains 2026: Complete Guide to All 10 Content Areas article walks through every domain in depth. This article stays focused on what the name itself signals about scope, format, and requirements.

How Part 1 Fits Into the Full EE-98 Classification

Earning the EE-98 Residential and Commercial Electrical classification isn't a single test - it's a three-part trade exam plus a separate Business and Law requirement. Part 1 (Commercial and Industrial) is what this site is built around, but candidates working toward full qualifying-party status also need to pass Part 2 (Residential) and Part 3 (Specialties), unless CID has approved an exemption for a specific applicant.

Business and Law is handled independently - either by passing a separate examination or by completing a CID-approved course. It is not folded into Part 1, Part 2, or Part 3 scoring.

Exam Format Behind the Name

Understanding what NM-EE98 Part 1 "stands for" also means understanding how it's actually delivered. Per the PSI bulletin revised April 3, 2026, Part 1 consists of 80 multiple-choice questions administered by computer, with 200 minutes to complete it. A score of 75% - 60 correct answers - is required to pass.

The exam is open book, but that comes with strict rules about what "open book" means here:

  • Approved references include the 2020 NEC or NEC Handbook, the 2020 New Mexico Electrical Code, and the 2007 National Electrical Safety Code.
  • References must be bound. Highlighting, underlining, and permanent tabs are permitted.
  • Handwritten notes, loose papers, and temporary tabs are prohibited.
  • A silent, nonprinting, nonprogrammable calculator is allowed.

If any of that catches you off guard on test day, it's worth reading NM-EE98 Passing Score 2026: Exactly What You Need to Pass and How Hard Is the NM-EE98 Exam? Complete Difficulty Guide 2026 before you schedule.

Key Takeaway

Bring bound, tabbed copies of the 2020 NEC, the 2020 New Mexico Electrical Code, and the 2007 NESC - not loose printouts or handwritten summaries - or your reference materials may be rejected at check-in.

The 10 Domains Inside Part 1

The name "Commercial and Industrial" covers ten distinct content domains, each with its own question allocation out of the 80-question exam. Knowing these weights is essential to studying efficiently.

Domain 1: General Knowledge and Electrical Installation Requirements (13 questions)

The largest single domain on Part 1. Covers foundational installation requirements that apply broadly across commercial and industrial work.

  • Highest-weighted domain - prioritize accordingly

Domain 2: Services, Feeders, and Branch Circuits (10 questions)

Sizing, calculations, and requirements for getting power from the source to the point of use.

Domain 3: Overcurrent Protection (5 questions)

Breaker and fuse selection, coordination, and protection requirements.

Domain 4: Grounding and Bonding (10 questions)

Tied for second-highest weight; a domain that consistently trips up candidates who skim it.

Domain 5: Conductors and Cables (8 questions)

Ampacity, insulation types, and application rules for conductors and cable assemblies.

Domain 6: Raceways and Boxes (8 questions)

Sizing and fill calculations, plus installation requirements for raceway systems and enclosures.

Domain 7: Hazardous Locations, Special Occupancies, and Special Equipment (10 questions)

Classified locations and equipment rules specific to commercial and industrial settings.

Domain 8: Lighting, Signs, and General-Use Equipment (6 questions)

Installation and circuiting requirements for lighting and general-use equipment.

Domain 9: Motors, Transformers, and Generators (6 questions)

Sizing, protection, and installation requirements - a common source of calculation-heavy questions.

Domain 10: New Mexico State Code (4 questions)

Amendments and provisions unique to the 2020 New Mexico Electrical Code.

For a domain-by-domain study strategy rather than just the question counts, the NM-EE98 Exam Domains 2026: Complete Guide to All 10 Content Areas article is the natural next stop.

Who Actually Sits for NM-EE98 Part 1

Understanding what the name stands for also clarifies who this exam is for. Part 1 is taken by individuals pursuing the qualifying-party role for a New Mexico EE-98 Residential and Commercial Electrical contractor license - typically experienced electricians preparing to run or supervise a licensed electrical contracting business rather than just work under one. It's also relevant to anyone holding a CID-approved NASCLA credential who still needs to satisfy New Mexico's experience and Business and Law requirements, since a NASCLA waiver removes only the trade-exam requirement.

Registration, Fees, and Approval Timeline

Because "NM-EE98" describes a licensing pathway and not just a single test, the fee structure spans more than the exam itself:

  • Qualifying-party application: $30, plus a $6 certificate fee per classification.
  • Initial three-part trade exam fee: $269.06 (covers Parts 1, 2, and 3).
  • Failed-part retake: $89.69 per part.
  • Business and Law examination: $68.88, if satisfied by exam rather than an approved course.

Applicants need four years (8,000 hours) of relevant experience along with a notarized application and experience affidavits, and CID must approve the application before testing is scheduled. That approval is valid for six months, and once you pass, your exam scores remain valid for one year. A full cost breakdown, including how retake fees add up if you need multiple attempts, is available in NM-EE98 Certification Cost 2026: Complete Pricing Breakdown.

Once licensed, contractor licenses renew every three years, contingent on the qualifying-party signature and bond coverage for the renewal term. Note that a qualifying-party certificate is only valid while attached to an active license and gets canceled after two consecutive years unattached - a detail that matters if you plan to change employers or start your own firm later.

Scheduling Note: Because approval lasts only six months and exam scores are valid for one year, timing your Part 1, 2, and 3 attempts matters as much as studying for them. See NM-EE98 Exam Dates 2026: Testing Windows, Deadlines & Scheduling for how to sequence testing windows.

Preparing Around the Name, Not Around Assumptions

Because "EE-98" is shared by other unrelated credentials online, one of the biggest risks candidates face is accidentally studying material that doesn't match this specific New Mexico exam. Before you start pulling study resources together, confirm they reference the PSI bulletin for New Mexico's EE-98 classification, the 2020 NEC/NEC Handbook, the 2020 New Mexico Electrical Code, and the 2007 NESC - not a generic national exam outline.
