SER cable

[aesllc]

I'm not sure about using SER cable for a commercial application. I'm wiring a two tenant space with a main breaker meter can. I want to run SER up a wall and above the first tenant space drop ceiling to feed the second space panel.

NEC '05 338.10(4) (a) refers me to parts I and II of article 334 for SE wire. The building is a 1 floor space divided into two spaces. The exterior walls of the building are brick and cinder, the remaining of the building is built and remodeled in conventional timber framing. I'm not quite sure how to classify the structure type and if my application falls in the proper use of the SE cable for that type.

Any suggestions would be appreciated.

You need to check with your local inspection dept on this issue.

if you have plans, look on the plans for the construction type of the building

Part II of 334...specifically 334.12(A)(2) does not allow the installation of SE here.

334.12 - Uses Not Permitted.
(A) - Types NM, NMC, and NMS.
(2) - Exposed in dropped or suspended ceilings in other than one- and two-family and multifamily dwellings

I do find this humorous:
334.12 - Uses Not Permitted.
(A) - Types NM, NMC, and NMS.
(3) - As service-entrance cable

338 tells us to follow 334....but then 334 tells us SE is not to be used as Service Entrance cable

Good catch Celtic. You may need to pipe this or use some MC cable.

Not knowing where the OP was located at, my response was based soley on the '05 NEC.
