What the Idaho Limited Electrical Elevator Installer Exam Covers

The official content outline has 7 topics:

How to Prepare for the Idaho Limited Electrical Elevator Installer Exam

Start with the books. This is an open-book exam, so the references on the bulletin's list are your main study tool. Get the editions the bulletin names.

Learn where things are. Read the table of contents and the index of each book until you know where every major subject lives. On test day, finding an answer fast matters more than memorizing it.

Highlight the sections you use most. The exam facts above list the bulletin's rules on tabs and markings, so follow them exactly.

Take timed practice exams. The clock trains you to find answers at the pace the real exam needs: about 3 minutes per question.

Aim to pass more than once. One passing score can be luck. Several in a row means you're ready.

Reference Books for the Idaho Limited Electrical Elevator Installer Exam

The 2017 NFPA 70 National Electrical Code is the allowed reference, and the 2017 Ferm's Fast Finder Index, 2017 Key Word Index by Tom Henry and Ugly's Electrical References may also be used as optional references not used to develop the exam.

Where to get them:

• NEC 2017

On Test Day

• Go through the whole exam first. Answer every question you know and bookmark the ones you don't. Every exam lets you come back to bookmarked questions.
• Then go back to your bookmarks and work them out.
• Don't let one question eat your time. You have 3 hours for 60 questions, which is about 3 minutes per question.
• Before you finish, answer anything you skipped. A blank can't earn a point.

Study Tips

Take this practice exam several times. The goal is to consistently clear your exam's passing score — often around 70–75% — so passing feels routine before you walk into the real test.

Only select answers that directly respond to the question asked—not ones that merely sound correct or seem true. After choosing, verify your answer against the question to confirm you didn't misread it and that your selection genuinely addresses what was asked.

Our practice exam is specifically designed to mimic the testing conditions at all exam centers. While untimed PDF study guides might help with studying, they don’t prepare you for the challenge of managing your time during an actual test.

Know your way around each book's index and table of contents. Open-book exams reward speed: you need to find specific items quickly.

Sample Idaho Limited Electrical Elevator Installer Practice Questions

These questions come from our practice question bank, each with its answer and reference.

Sample 1 — 2017 National Electrical Code, NFPA – Chapter 3

Question: You are installing a new panelboard in a concrete block wall. According to the NEC, how far back from the finished surface is the front edge of the cabinet permitted to be set?

• A. Not more than ¼ inch
• B. It must be flush with the finished surface
• C. Not more than ½ inch
• D. Not more than ⅛ inch

Correct Answer: A

According to the National Electrical Code Handbook, Article 312.3 (Page 285), in walls of concrete, tile, or other noncombustible material, cabinets shall be installed so that the front edge of the cabinet is not set back of the finished surface more than 6 mm (¼ in.).

Reference: NEC 2017 Section 312.3

Sample 2 — 2017 National Electrical Code, NFPA – Chapter 4

Question: A time-delay (dual-element) fuse sized at the standard table percentage is not sufficient to carry the starting current of a squirrel-cage motor. The fuse rating is permitted to be increased, but in no case shall it exceed what percent of the motor full-load current?

• A. 200 percent
• B. 175 percent
• C. 400 percent
• D. 225 percent

Correct Answer: D

NEC 430.52(C)(1), Exception No. 2(b) permits the rating of a time-delay (dual-element) fuse to be increased but in no case to exceed 225 percent of the full-load current. The 175 percent figure is the standard Table 430.52 value; 400 percent applies to nontime-delay fuses and certain inverse time breakers.

Reference: NEC 2017 Section 430.52(C)(1), Exception No. 2

Sample 3 — 2017 National Electrical Code, NFPA – Introduction

Question: Which chapters of the Code apply generally to all electrical installations?

• A. Chapters 1 through 3
• B. Chapters 1 through 7
• C. Chapters 1 through 4
• D. Chapters 5 through 7

Per NEC 2017, 90.3, Chapters 1, 2, 3, and 4 apply generally. Chapters 5, 6, and 7 apply to special occupancies, special equipment, or other special conditions and may supplement or modify the requirements in Chapters 1 through 7.

Reference: NEC 2017 Section 90.3

Sample 4 — 2017 National Electrical Code, NFPA Calculations

Question: According to NEC Article 430, what values are used to determine the ampacity of conductors and ampere ratings for motor branch-circuit short-circuit and ground-fault protection for general motor applications?

• A. The values given in Tables 430.247 through 430.250
• B. 125% of the motor nameplate current
• C. The locked-rotor current of the motor
• D. The actual current rating marked on the motor nameplate

Correct Answer: A

According to the National Electrical Code Handbook (Page 496), NEC 430.6(A)(1) requires that for general motor applications, the values given in Tables 430.247 through 430.250 shall be used to determine the ampacity of conductors or ampere ratings of switches, branch-circuit short-circuit and ground-fault protection, instead of the actual current rating marked on the motor nameplate.

Reference: NEC 2017 Section 430.6(A)(1)

Why Practice Online Instead of With a PDF

A PDF shows you questions. It doesn't show you the clock. Our practice exams are timed and on a screen, so you practice finding answers under time pressure, not just reading them. Each attempt draws a new set of questions from our bank, and your results break the score down by outline topic so you know what to study next.
