      You have what appears to be a BX cable penetrating and indoor wall to a garage. This needs fire stopping to meet code.

      Here is Hilti’s drawing showing the wall assembly and how it can be fire stopped with their products. The optional metal conduit pictured would make it cleaner but also require disconnecting the cable.
