My friend and I are discussing artical 338 for using type SER cable as a feeder to sub panels and as a branch circuit to rooftop HVAC units in a two story commercial office building.

I have read Art. 338.10 (B)(4)(a) which refers me to Art. 334 Parts I and II excluding 334.80 which deals with Ampacity.

I believe the entirety of article 334 applies to the installation of type SER installed inside as a branch circuit or feeder, and as such section 334.12 "uses not permitted" ..... 334.12 (A) (2) indicated to me that if the cable would be exposed within a drop ceiling it may NOT be used.

My friend claims that Art 334 does not "mention" SER cable specifically so it would not apply.

What do you guys think ?
 
I agree with you.

338.10(B)(4)(a) requires that when SE cable is used in the interior of a building for branch circuits or feeders the cable must comply with the installation requirements of Part II of 334.

334.12(A)(2) is located within Part II of Article 334, so I feel that you can't install exposed SER cable above a suspended or dropped ceiling.

This does not include 1 or 2 story family or multifamily units for those following along at home. :)

I agree, I posted that comment in regards to 334.12(A)(2) which states "Exposed in dropped or suspended ceilings in other than one- and two-family and multifamily dwellings". ;)

I just didn't feel like quoting the entire section since I had referenced it.:)
