SER cable ampacity

[nizak]

Am I correct in saying that type SER cable used to feed a sub panel in a residence has to be calculated using the 60 deg table for ampacity?

The same as NM-B cable would be.

Thanks

Not necessarily but it depends on what code cycle you are using

What code cycle this one has changed multiple times in the past few cycles. Here's the 2017 version.

338.10(B)
(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.
For Type SE cable with ungrounded conductor sizes 10 AWG and smaller, where installed in thermal insulation, the ampacity shall be in accordance with 60°C (140°F) 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 60°C (140°F) rated conductor.

Depends on your Code cycle.
If I recall correctly your statement is accurate for the '08 Code; in '11and '14 the 60° olny applied to SE in insulation; and in '17 its practically disappeared,

(opps.. I was digging thru Code books as my colleagues answered)
