- This practice test consists of Free National Electrical Code (NEC) 2017 questions. This practice exam helps for preparing Journeyman & Master license exams.
National Electric Code (NEC) is a standard adopted in United States of America for safe installation of electrical wiring and components. For obtaining license for carrying out electrical related works, in depth understanding of the code is necessary. Almost all the license exams will have a section related to NEC code. NEC code is not a book to read just before the exam. The best way to learn the NEC Code is through interaction with others (group study) and attempting number of practice tests.
NEC Code consists of 9 chapters each dividing into four groupings: General Requirements; Specific Requirements; Communications Systems and Tables
Chapter 1: General
Chapter 2: Wiring and Protection
Chapter 3: Wiring Methods and Materials
Chapter 4: Equipment for General use
Chapter 5: Special Occupancies
Chapter 6: Special Equipment
Chapter 7: Special Conditions
Chapter 8: Communications Systems
Chapter 9: Tables - Conductor and Raceway Specifications
Thanks for making this test vid btw... I didn't mean to sound un-grateful for the effort put into making and sharing this sample test.
Concise and to the point. Appreciate it.
To start, for clarification I understand these practice questions are based on the 2014 edition of the NEC. Any corrections I am applying here are only based on those books, and not on newer editions of the NEC. Please like to keep this collected information to the top, hoping to help anyone else who was further confused by this sample test. I appreciated the test not only for its intended purpose, but also for the extra work I had to put in to figure out these corrections. It helped me navigate the code alot faster than just answering the questions I think.
34. Reference is Article 250.21(B)(2), not the one mentioned.
38. The article number referenced is correct, 680.7, its specifically 680.7(A) and the quoted article is not that article. Additoinally, the question was worded terribly, and does not mention that it talking about the length of cord. The way the question is worded, its asking the length of of the equipment, not its wiring.
40. Quoted article has nothing to do with the question and answer. The actual article reference is 312.8(1).
41. The quoted article was close(numbers mixed up), but not correct. The correct article is 250.34(A).
48. The quoted article is incorrect. The actual article reference is 210.23(A)(1).
50. The quoted article was close, but not exactly correct to provide the answer. Specifically, it is article 680.26(B)(7) Exc. No. 2.
51. Quoted article is completely correct, though there are two paragraphs to the article, and only the paragraph that doesn't explain the answer was quoted.
52. Quoted article is correct, though specifically the answer is in 240.21(B)(1).
56. The question should have specifically stated that it meant for multiple separately derived systems. Based on the question asked, the answer would be 8 AWG. Specifically for separately derived systems, yes it is 3/0 AWG.
57. The article quoted is close, but does not answer the question. The specific reference article is actually 250.53(G).
59. The word "not" was excluded from the question. It is an important difference to say "rated not less than" vs. "rated less than".
I thought these questions were based on 2017 NEC…?
@@matthewellis3004 No. The current test is most likely depending on where you are located, this video is not. I reviewed each question and there were different answers for some in the 2017 or newer versions, while the answers they gave were correct based on the 2014 version.
Thanks
I was wondering /worried about some inconsistencies ... You da man!
Q10 explanation should be.. Article 100. Definition of Continuous Load. A load where the maximum current is expected to continue for 3 hours or more.
Love this video learning more than normal
thanks for making this video ! . it helped me discover and practice my own way of navigating the NEC book.
Where I am sure question 37 is used in most exams across the US, it is a terrible question. It is taken completely out of context and here is why that is a problem: 408.54 states "for the purposes of this section". 230.90(A) uses the language "Single pole circuit breakers grouped in accordance with 230.71(B) shall be considered as one protective device." Perhaps there needs to be more context to avoid confusion of where this rule applies.
56 under what conditions? This is for "multiple separate derived systems" which would likely be stated in a real test question.
Ok, so Answer 3 about Article 680.10 is coming from 2011 code and 2014 code book cycles. The information was revised in the 2017 and moved to article 680.11 Underground Wiring code cycle and the verbiage dose not reflect the 2011 or 2014 code cycles. in the 2020 code cycle it has been revised and new sections have been added.
The theory of this Practice Exam is well-founded. And some of the answers even match the questions. But not all of them. Some are completely unrelated. Nor can those taking this exam even verify whether the answers are correct. I feel as though everyone who saw this video is now dumber for having experienced this. I award you no points, and may God have mercy on your soul.
Question 8 is asking about disposal, the code reference is 422.16 (B) (1) not (2)
Question#41 references article 445.20 not 230.54(a) overhead service locations
Yeah, I was thinking what the actual F---
question #1 where it says 6 in the 511.3 ? i do not see it
I have the 2020 code book its under 511.3(C) apparently its 4 changes this video is wrong... i think this is from the 2017 code book
This video might have been useful a few code cycles ago but only three questions in and two code references have been change already. Would love to an updated test with 2017 NEC questions. Thanks
Why not an update with the 2020 NEC Code ? 2017 is outdated.
@@longshankdrills8799 everybody still using 2017, and it’s what is used on the PE test as well.
@@electroduval831 yeah I know that's what they use on the test, but the fact remains 2017 code book is outdated ! I personally use the 2020 code book because it's current.
Which is the most commonly referenced version of the NEC book. I purchased and tabbed a 2020. I have a '17 (not tabbed) and a '14 I havent seen for a while. Does the testing company supply a version of the test to correspond with the book edition you bring to the testing location?
lets do the 2023 code.
Question#50 answer is in 680.26 (B)(7) Fixed Metal parts
question 40 answer is in article 312.8 (a)(1) 2020 nec
Where to download the test to practice ?
I think the thought was there but if your going to give reference numbers to questions at-least get them right
Good video
did not find the answer of question #1 in table 511.3.C
Any other videos on RUclips with 2020 questions
Im worried this test will cause me to second guess some of the items I know are right... Is there an edited make of this vid with the right answers?
Although personally I'd say the people smart enough to catch the errors are probably ready for their exams. Just my 2¢
The code reference for Q36 is 440.62-C
36, explanation is needed. 440.62 (C)
Question 40?
There’s no reference in the code sited
Tanks
Question#48 answer is in 210.23 (A)(1)
Could someone mention if these answers are conditioned for this current year's exam? 2022... thanks
I would say yes but you need to know
How to do calculations
How many questions you can miss on each of these test.
We need other videos
Muy buena la información para surrallar el libro de codigo
This was solid. thank you!
Note this is from the 2017 NEC
First Question Wrong Answer! 2017Nec Requiers 4 cycles of air per hr. Or Positive air presure. Table 511.3(c)
Right off the bat . The answer to question #1 is NOT "6" , (511.3(C)) It states "4 or more air changes per hour) !!! Nowhere does it say "6" ... And "4" is among your answers to chose from. As well as "6". So, WHY is the answer "6" and NOT "4" ??? 🤔
You might want to double check!!!
because handbook figure 511-1
@@oswaldor37 I'll check, thanks !!! 👍
i checked both 2017 and 2020 fumbuzzled
I saw “4” not “6”
Nec 2020
There is so much wrong with this video. The answer is circled in the question following an explanation that’s missing the answer that was circled. Needs revising!
i need Electrical QA QC Engineer Material
no wonder i failed 2017 using 2020. testing centers get with the times
Q.34 is 250.21(B)(2)
👍
Can a handyman come and fix your electrical problem in Hayward California for Alameda County in California
Question 43 you said the grid supports the wire,, that’s backwards
I don't mean to be critical but there are quite a few verbal mistakes being said in this video. Question 37 you said 508 when it's 408 and then earlier you said question number 8 on question number 9. Then there was some repeat glitch on a question. Now I have to call into question the entire video and I don't have the brain power for that! lol
Thenks miss for you help
Simply brilliant.
How did you get 6 for the first question all I see is 4… This is a 2023 NEC
for #30 look at 400.12
Definitely giving wrong answers.
Yall gotta get these explanations right
necesito ayuda yo no hablo muy bien el ingles e tomado 2 veces el exxamen y me quedado corto la 1era ves por 9 puntos y la 2da ves x 5 puntos alguien k ya a pasado el examen que me pueda dar unos tips para poder pasarlo se lo agradeceria muchas gracias y bendiciones
Lo volvisteis a tomar ? De donde eres
Question number 37 you said 508 and it’s 408
annoying presentation....do you really need to read the answers or the code selection. And like comments below, code references are wrong on occasions but I found the correct code link....I finished the video but not thinking I will use again...
Number one is 4 not six.
Idk what y’all are talk about every question I’ve seen matches in my book haven’t made it all the way through this video though
What code book are you using?
Al lot of these gave the wrong article. But I got an 80% and I’ve only been studying for 2 weeks
52 is not correct...taps may over 25 feet without overcurrent protection provided they comply with B1-B5...
42 doesn't quite make sense...
too many "no explanation needed"s...there are plenty of code examples to better explain them.
Question 40s answer had nothing to do with the question,,
A lot of the explanations are wrong
Definitely disappointed, way too many errors
👍🏽
Awful. Wrong or missing code refrences everywhere
You stole every single question off electricianexamspracticetest.com (absolutely identical) I will be contacting them and letting them know to hit you with a copyright infringement violation.
Man.... I'm over stressed the hell out and I haven't got passed the first dammmm question..... lol. THE ANSWER shows 4 in ther code but she says 6.... wtf.... never mind... i'm done with this shiiit
Q41 ummm i think the explanation is wrong. apples and oranges ya know.
This is mindless reading of someone's test that has a F on it.
680.11 no 680.10 you fail
ESPAÑOL!!!
Learn fucking English
#8 is wrong, it says 3ft to 6.5 ft
A large number of mistakes on the explanations. Do a better job if you’re going to make a video to teach people about code. Maybe review it before you send it.
To me, question 41about portable generators and the answer given are two different subject matters. If you can not verify your answers, get off U Tube.
