To maintain UL Classification on cellular deck applications, refer to the tables below for maximum quantity of conductors allowed
to exit activation covers. Refer to the UL Fire Resistance Directory for additional floor design information. Depth of concrete over
top of steel deck must be a minimum of 2 1/2" [64 mm]
NOTES:
(a) Maximum quantity of three-conductor
power supply cords (3/8" [9.5mm]
maximum diameter).
(b) Maximum quantity of No. 12 AWG
conductors allowed when a 1/2" through
1" trade size liquid tight steel conduit with
cast steel 90º elbow is connected to
access cover. When conductors larger
than No. 12 AWG are used, the aggregate
cross-sectional area of the copper
conductors shall not exceed the aggregate
cross-sectional area of
No. 12 AWG conductors.
(c) Maximum quantity of No. 24 AWG
conductors (4-pair communication
cable has eight conductors; 25-pair
communication cable has 50 conductors).
When conductors larger than No. 24
AWG are used, the aggregate cross-
sectional area of the copper conductors
shall not exceed the aggregate cross-
sectional area of No. 24 AWG conductors.
Maximum size of any communication
cable is not to exceed 25-pair (3/8"
[9.5mm] maximum diameter).
(d) Maximum quantity of No. 24 AWG
conductors (4-pair communication
cable has eight conductors; 25-pair
communication cable has 50 conductors)
allowed when a 1/2" through 1- 1/4"
trade size liquid tight conduit with cast
steel 90º elbow is connected to access
cover. When conductors larger than
No. 24 AWG are used, the aggregate
cross-sectional area of the copper
conductors shall not exceed the aggregate
cross-sectional area of No. 24 AWG
conductors. Maximum size of any
communication cable is not to exceed
25-pair (3/8" [9.5mm] maximum diameter).
(e) Where local codes permit, conduit
may be omitted when used for
communication type cables. A steel
conduit fitting or a nipple that extends
a minimum distance of 1" [25.4 mm]
beyond surface of cover assembly must
be utilized. Protect wires from damage by
installing a bushing suitable for use with
the type of fitting used. The diameter of
the conduit fitting opening for the passage
of cables shall be no more than 1/8 in.
larger than the diameter of the cable.
Use a suitable fire-resistive caulking such
as 3M Part No. CP 25WB to seal openings
around cables larger than 1/8 in.
