I just went thru the 10 Residential sample questions in the International Association of Electrical Inspectors’ applicant handbook. I believe that 3 of the 10 answers given in the answer key on page 14 are wrong. If anyone has time to go thru these let me know if you agree that 3 of the answers are incorrect. Which 3?
Here's the link to the handbook that contains the 10 questions starting on page 12: http://www.iaei.org/cei/CEIApplicantHandbook.pdf

Some of the questions in my opinion could have been better chosen.
# 1 is technically correct but not what anyone in the trade would answer
# 5 is correct if you remeber it is an ISLAND.
# 9 pools does not seem to be concise enough. 680.50 refers to Part II which is entitled Permanently Installed Pools.
Remeber that even missing these three your score would still be 70%, passing and allow you to move on to the practicum phase of the certification.

I forgot that the answers were listed on page 14. I was starting from scratch. (AN)

#1 - How do you figure that #1 is technically correct? The interupting rating of a circuit breaker is measured in VOLTS!! I don't see how this can be correct in any way shape or form. "not what anyone in the trade would answer" - so who would give this as an answer??

#5 - I have no problem with this one, a bit tricky perhaps but I agree with the answer.

#9 - one of the answers is "Permanently Installed Pools". This is a better, i.e. more concise answer than "Pools" thus the answer key is wrong. It should be A not B.

#10 should be A "identified for standby use" not D "rated for continuous use". 702.4 makes no mention of a transfer switch being "rated for continuous use".

Interrupting rating is a defined term in article 100.....

Right. Interrupting Rating - The highest current at rated voltage that a device is intended to interrupt under standard test
conditions.

So Alan, how do you figure the answer of "Volts" given in the IAEI sample question below is "technically" correct?

The interrupting rating of a circuit breaker is measured in which of the following?

I didn't write this test. In my original post I indicated that I answered them from the book and then realized that the answers were already available. That was how I determined which questions would be suspect. That is the ones I missed using the book.
That said, the answer for # 1 refers to section 110.9 Interupting Rating. It does not refer to definitions. If you read it carefully they stress that the operating voltage of a breaker is a known value.
The last sentence explains that the interupting level of current is variable.
Voltage is a defining criterial in selecting breakers. Not just 120/240 & 277/480 but, 480 Y & 480 delta. This became a problem when 3 Phs breakers were installed on a Delta panel with no midpoint ground. All line/phase to ground voltage was equal to phase to phase voltage.
I do not consider this a good question.

#9 Part II includes reflecting & other pools. Not just swimming pools.

#10 I put down A. Based on 702.4 If they have D as the answer then that is an error.
[Edit] Their answer is B, approved by AHJ. A blanket answer that is always right even when the AHJ is wrong.

Remember, finding the errors IN the test may be part OF the test.

Thanks for your views on these sample questions. I just think they did a poor job on the sample question section.
