How Many Outlets Or Recepticles On A Circuit??

K2

I know Ive read many times on these forums that there is no limit to receps on a resi circuit but i was in class the other night and the instructor, who was an inspector in 3 states, cited article 220.14 (i) and insisted that only 8 are allowed on a 15 amp and 12 on a 20.

I've read it over many times and believe the instructor to be incorrect on this. Am I right that he is wrong??

Also i was wondering where the article is that limits the outlets on commercial . Thanks !!!

220.14(J) Dwelling Occupancies. In one-family, two-family, and multifamily dwellings and in guest rooms or guest suites of hotels and motels, the outlets specified in (J)(1), (J)(2), and (J)(3) are included in the general lighting load calculations of 220.12. No additional load calculations shall be required for such outlets.
(1) All general-use receptacle outlets of 20-ampere rating or less, including receptacles connected to the circuits in 210.11(C)(3)
(2) The receptacle outlets specified in 210.52(E) and (G)
(3) The lighting outlets specified in 210.70(A) and (B)

As outlined above the receptacles can be added to the 3 watts per square foot and there is no requirement to use the 180 volt ampere rule of 220.14(I)

220.14(I) Receptacle Outlets. Except as covered in 220.14(J) and (K), receptacle outlets shall be calculated at not less than 180 volt-amperes for each single or for each multiple receptacle on one yoke. A single piece of equipment consisting of a multiple receptacle comprised of four or more receptacles shall be calculated at not less than 90 volt-amperes per receptacle. This provision shall not be applicable to the receptacle outlets specified in 210.11(C)(1) and (C)(2).

This rule is for commercial and industrial applications only.

The EI needs to keep reading (i) until directed to apply (j) [as precision detailed]

Agreed this is not for residential applications..only commercial and industrial Gen Purpose outlets.
220.14(j) being the correct exception to the (I) article.

"Also i was wondering where the article is that limits the outlets on commercial "

Article 220.14(I) IS the article that limits unknown or Gen purpose outlets for commercial applications...

"(I) Receptacle Outlets. Except as covered in 220.14(J)
and (K), receptacle outlets shall be calculated at not less than 180
volt-amperes for each single or for each multiple
receptacle on one yoke."
