Print it out.....Work it out.......send me your answers and I just may give ya something.....

[Greg Fretwell]

No offense intended but some of your quetions are worded such that it is hard to figure out what you are asking.

[Paul W. Abernathy]

Lol.....none taken. but i use a database of questions from a software i use.....i did not write them.

They are based on 2008 NEC Updates and i had no trouble when i did it before posting it.....they are tough questions but the answers are found only using the 2008 code book.....the key to finding them is actually in the question for the most part.

[Paul W. Abernathy]

Oh......the blanks arw actually filled with the EXACT word as in the code book. Disect the article or section needed by the keys in the question.

From what i gather the software i use makes you really dig to find the verbiage in the code.....these questions are based on changes for 2008......

[Greg Fretwell]

It looks like an exercise in using the text search function on the CD more than actually testing useful knowlege.

[Paul W. Abernathy]

That would be cheating Greg.....lol

I find them easy....The concept of learning the NEC is by repeating look up exercisees...you learn as you explore. These questions are based on the 2008 Changes.

Most of the questions are done in a style that gives you a hint of the article or section to look in contained in the question itself. Just by looking it up, understanding the question will aid in learning.

"15. Older vending machines manufactured or remanufactured prior to January 1, 2005, shall be connected to a(n)"

I'm trying to recall the last time I saw a vending machine in a house...

Keg machines don't count!

[Paul W. Abernathy]

lol.......well considering NACHi is promoting "Commercial Inspection" courses all over the place........i see it possible they will face an outside receptacle that may get a vending machine.....and it shoukd have a GFCI receptacle on that location.....

lol......so since NACHI is going commercial...lol....why not...

What about indoor vending machines?

Would not matter....422.51 states Cord and Plug connected vending machines manufactured on or after January 1 , 2005 shall include a ground fault circuit interrupter as an intergral part of the attachment plug or be within 12 inches of the attachment plug......IE: GFCI receptacle.

"Older vending machines manufactured or remanufactured prior to January 1, 2005 SHALL BE connected to a GFCI outlet.....which opens it up to allowing a GFCI breaker option.

as for indoors or out becomes moot....since if it is outside and subject to the public per another 2005 change..210.8(B)(4)...it would have to be GFCI anyway......so this change deals directly with Vending Machines as a statement.

Now.......please dont ask me to define a Vending Machine..lol

I now am starting to think about the liability issue here with a "Vending Machine" on a small commercial inspection (convience store - where the most intelligent and common sence people work at) that require cooling such as sandwiches, ice cream, beer (cold to hot to cold can cause it to go flat), etc. if the GFCI was tested or accidentally popped during a inspection and no one noticed for a while. kinda like what we face in the home when a small freezer and/or Refrigerator is found connected to GFCI's in basement or garage locations.. I guess I had better put this little tidbit reminder on my small commercial worksheets I use on site for my inspection report..........geez will it never stop...

[Greg Fretwell]

I had this discussion with Fl IAEI about an ice machine. The consensus was, if you didn't have to put money in it, it wasn't a vending machine. I wasn't sure how money caused electrocution but there you go.
BTW this came about because of a kid being electrocuted by a candy machine (no ground pin on the plug). I guess if they got electrocuted by a slurpie machine they would have to be GFCI now.

[Paul W. Abernathy]

Remember we are speaking of vending machines.....not coolers wher you open the door and pick up a sandwich and take it to the counter.
We must know the definition of "Vending Machine"....the aspect of public safety more than out weighs a few flat coke cans...lol

BTW......the quiz was just if people want to try it........if people dont thing taking quizzes and testing knowledge (if one chooses too) does not aid in learning....they are mistaken...

Our goal ( as with joe t and his posts if he does not mind me speaking for him) is to just help broaden your knowledge ..not to make HI'S quote anything.....all about learning from educators willing to give of FREE time to help others.....sorry...just ranting for those who say things like this has no relation to home inspectors....this is where i disagree .. . . . Education is worthy no matter what it is.....

[Paul W. Abernathy]

Lol.....Greg you kill me.....but we did the requirement for GFCI on public water fountain receptacles....so watch out for that 2011 submission on Slurpie Machines.....

2008 NEC

422.51 Cord-and-Plug-Connected Vending Machines.

Cord-and-plug-connected vending machines manufactured
or re-manufactured on or after January 1,2005,shall in-
clude a ground-fault circuit interrupter as an integral part of
the attachment plug or be located within 300 mm (12 in.)of
the attachment plug. Older vending machines manufactured
or remanufactured prior to January 1,2005,shall be con-
nected to a GFCI-protected outlet. For the purpose of this
section,the term vending machine means any self-service
device that dispenses products or merchandise without the
necessity of replenishing the device between each vending
operation and is designed to require insertion of a coin,
paper currency, token, card, key, or receipt of payment by
other means.

Standard for Refrigerated Vending Machines ,or ANSI/UL
751-2005,Standard for Vending Machines .
