From 2011 NEC Article 338.10 (B) 3 & 4:

"(3) Temperature Limitations. Type SE service-entrance
cable used to supply appliances shall not be subject to conductor
temperatures in excess of the temperature specified
for the type of insulation involved.
(4) Installation Methods for Branch Circuits and Feeders.
(a) Interior Installations. In addition to the provisions
of this article, Type SE service-entrance cable used for interior
wiring shall comply with the installation requirements
of Part II of Article 334, excluding 334.80.
Where installed in thermal insulation, the ampacity shall
be in accordance with the 60C (140F) conductor temperature
rating. The maximum conductor temperature rating
shall be permitted to be used for ampacity adjustment and
correction purposes, if the final derated ampacity does not
exceed that for a 60C (140F) rated conductor.
Informational Note No. 1: See 310.15(A)(3) for temperature
limitation of conductors.
Informational Note No. 2: For the installation of main
power feeder conductors in dwelling units refer to
310.15(B)(7).
(b) Exterior Installations. In addition to the provisions
of this article, service-entrance cable used for feeders or
branch circuits, where installed as exterior wiring, shall be
installed in accordance with Part I of Article 225. The cable
shall be supported in accordance with 334.30. Type USE
cable installed as underground feeder and branch circuit
cable shall comply with Part II of Article 340.
