utilizes TSI thermo-lag l
material in one fire area for a short section of cable in conduit to meet Appendix R

However, the conduit is five (5) inches in diameter and, as such, does not apply to the compensatory measurec of the Bulletin which considers "small size conduit" as four (4) inches or less in diameter.
