Hi guys...the TC-ER cable is a Tray Cable and can not be used inside a building unless in cable tray or a raceway. That TC-ER cable was supposed to pick up a listing for use in 1&2 family dwellings in accordance with 2017 336.10(9) with a new marking "JP" for joist pull. So you would see TC-ER-JP...but I have not seen any of it on the streets.

There is a product in the supply houses around here that some are starting to use...

Here is a link...
