I say 4 because when you calc load based on 180va whether it is a single or a duplex,,,,,,,,,,,,so if it were 8 then the load would not agree with the rule as counted against the number of symbols.

Dick, read post #9 or go directly to 210.14(I) the NEC has already taken care of your scenario.

Nope don't think so.....

Let me try a different approach for and explanation dictating 4.

The dwg shows 4 symbols that could mean either a single or a duplex which in either case is still a total of 720VA. If you think there are 8 then the total would be 1440VA, but this can't be because there are only 4 symbols that dictate a max is 720VA.;)

Dick, this is where you need to read the article a little slower, what do you interpret this
receptacle outlets shall be calculated at not less than 180 volt-amperes for each single or for each multiple receptacle on one yoke.

to mean? ;)

Dick,

Also, don't forget the OP is the driving question, and it is not an Article 220 question.

. . . a test that has this question:

How many receptacles are connected to circuit 24 from panel RPB in the manufacturing facility

The plan shows four duplex symbols on that circuit. . . .

And, since Nathan shared the test answer was "4", its not even a NEC question and answer, IMO.
 
I see where you are coming from on that,the word "multiple" throws a kink in the works , if it had been omitted then 8 jumps right into the picture .

The stumbling block here is that word "multiple" , at first glance I read a "multiple receptacle" to mean one receptacle,,,,,,,,,,but this has nothing to do with the OP,I was using that 180va thing to find the answer and it got me into trouble,,,thats not an excuse its a fact:)D)

The info that falls out in discussion is teaching incognito.I challenge rather than accept, this helps me to understand and more so helps me retain the answer.

Note: The author must also write Law Books:)

In my world, we include a drawing called "Legends and Abbreviations." That drawing would show different symbols for simplex receptacles and for duplex receptacles. The same symbol can't be used for both devices. Generally, a simplex symbol is a single line through a circle, and a duplex symbol adds a second line. There are other nuances that convey whether the receptacle is mounted in the ceiling, the wall, or the floor, and whether they are above or below a horizontal surface (desk or countertop). So that part of the question should not be a source of controversy.
 
Exactly right Charlie, my mistake and I knew better, as I too have used those exact symbols.

I have thrown in the towel and agree it would be 8.
