3.7 Cable Compartment
The cable compartment is designed to allow both top and bottom
entry of cables. Several different methods can be used when pen-
etrating the top roof sheet and/or bottom pan. Conduit compression
hubs are the preferred method to limit potential arcing gases from
escaping the equipment. When this type of hub is not used, other
types of cable fittings can be used, but it is the installer’s respon-
sibility to seal any openings, up to ¾ in. with duct seal. Openings
larger than ¾ in. are not allowed. When conduit stub ups are used,
in a slab, the bottom pan must have holes cut into it to allow the
conduit to pass through while maintaining the no larger than ¾ in.
