SER Cable

[dav5y]

Hi All,

I'm confused..... What ampacity table in the NEC is for SER cable. Please note the cables will be installed inside a mult-dwelling unit.

It is based on 60C column.

For interior installations, the ampacity of Type SE cable used as feeders or branch circuits is determined by following the requirements of 334.80.

The ampacity of Types NM, NMC, and NMS cable shall be determined in accordance with 310.15. The ampacity shall be in accordance with the 60?C (140?F) conductor temperature rating. The 90?C (194?F) rating shall be permitted to be used for ampacity derating purposes, provided the final derated ampacity does not exceed that for a 60?C (140?F) rated conductor. The ampacity of Types NM, NMC, and NMS cable installed in cable tray shall be determined in accordance with 392.11.
