INSTALLATION INSTRUCTIONS

Installation Instruction No.: 1 002 947 R3 – Updated April 2005

Wiremold Electrical Systems conform to and should be installed
and properly grounded in compliance with requirements of the
current National Electrical Code, Canadian Electrical Code or
codes administered by local authorities.

All electrical products may represent possible shock or fire hazard
if improperly installed or used. Wiremold electrical products are
UL Listed to U.S. and Canadian safety standards, made for
interior use only, and should be installed in conformance with
current local and/or the National Electrical Code.

IMPORTANT: Please read all instructions

before beginning.

Products Covered: RC9STC, RC9A15TC, RC9CTC, RC9SHTC, RC9A15TC-LJB and RC9A15TCLJB25

CAUTION: Do Not operate tile stripper or resurfacing equipment over top of covers. This may result in damage to the

surface finish of the product.

Suitable for use in air handling spaces in accordance with Sec. 300-22 (C) of the National Electrical Code.

Step 1 Layout and locate position

of hole(s).

Step 3 Core drill hole.

Step 4 Stem Assembly

Catalog No. RC9STC
Insert stem into hole.

Step 5 Cover Assembly

Catalog No.: RC9CTC
Remove disposable plate
and replace with carpet/tile
flange. Install with (4) #6-32
x 1/4" [6.4mm] FHMS

Step 2 Remove 6 1/2" [165mm] section from carpet

or tile. Use template provided.

CAUTION: Holes shall be spaced a minimum of

2' [610mm] on center and not more
than one hole per each 65 sq. ft.
[6 sq. m] of floor area in each span.

NOTE: Be certain to drill hole at least 4" [102mm] from any wall or

pillar to leave enough room for poke-thru cover assembly.

NOTE: For tile installations up to a maximum of 3/4" [19.1 mm] thick.

For tile thickness greater than 3/4" [19.1mm] consult factory.

Wire the Poke-Thru device (Can be completed
above floor). Refer to wiring schematic in Step 8.

Step 8 Connect Poke-Thru conductors according

to required device configuration. See
schematic below.

Step 7 Wire the POWER circuit.

WARNING: Ground wire from junction box must

be connected to SYSTEM GROUND.

CAUTION: Receptacle mounting means not grounded.

Grounding wire connection required. For isolated
ground wiring, connect ground leads to a separate
isolated grounding conductor. See NEC 250-146(d).

NOTE: The orange triangle shall only be placed on devices that

are wired for isolated ground. See NEC 250-146(d).

NOTE: When installing Cat No. RC9CTC to existing stems, apply

wiring label to the inside of the junction box cover.

CAUTION: To maintain UL Fire Classification, Slide Cover

must be replaced when communication cables
are removed. Order Cat.No. RC9SHTC.

CAUTION: Gasket must be set in place to provide scrub water

seal. Do not over-tighten Cover Mounting Screws.

Step 10 Communication Wiring

For cable pass-through, remove the egress
knockout located on the underside of the cover

Step 11 Attach Slide Cover with (2) #6 screws. Pass-

through cabling must pass through internal
gasket and data slide.

The RC9TC Series Poke-Thru Device is UL Listed and Classified to U.S. and Canadian safety standards to the
following conditions:

The RC9STC Poke-Thru Stem with the RC9CTC Service Head Fitting, the RC9A15TC factory assembled Poke-Thru
device, and the RC9APTC Abandonment Fitting are for use with 1-, 1 1/2-, or 2-hour rated unprotected reinforced concrete
floors and 1-, 1 1/2-, or 2-hour rated floors employing unprotected steel floor units and concrete topping (D900 Series Designs),
or concrete floors with suspended ceilings. (Fire resistive designs with suspended ceilings should have provisions for accessibility
in the ceiling area below the poke-thru fittings).

The assembled Poke-Thru stem and service fitting or the abandonment fittings will not reduce the ratings of the floor assembly
when the thickness and type of concrete (required for the specific rating) are within the specified limits and the fittings are
installed as specified:

1. Spacing – Minimum of 2' [610mm] OC and not more than one unit per 65 sq. ft. [6 sq. m] of floor area in each span.

2. Concrete – Minimum thickness of structural concrete topping of 2 1/4" [57mm] over metal deck or a minimum 3" [76mm]

thick reinforced concrete slab. Unit weight of concrete to be 110 to 155 pcf.

3. Installation – Mounted in a 3" diameter core-drilled hole in concrete per installation instructions accompanying
the fittings or abandonment fittings. For use with power circuits, data and/or telephone cables as tabulated below:

The “TC” suffix letters indicate that device may be installed on tile or carpet covered concrete floors. The “LJB” suffix
letters indicate units supplied without a junction box. The "25" suffix numbers indicate units supplied with 25 foot
receptacle leads.

(A) Maximum number of No. 12 AWG Type THHN conductors in power compartment of Poke-Thru fitting.

(B) Maximum number of 22 AWG conductors in low voltage compartment of poke-thru fitting (4-pair cables have (8)

conductors). When conductors larger than No. 22 AWG are used, the aggregate cross-sectional area of the copper
conductors shall not exceed the aggregate cross-sectional area of the 22 AWG conductors permitted in the low
voltage compartment.

For use on carpet covered and tile floors up to 3/4" [19.1mm] thick.

CAUTION: Receptacle supplied with this Poke-Thru is not suitable for direct field wiring. Contact manufacturer for

replacement. Field modifications will void UL Listing and Classification. Repalcement receptacle is limited
to this manufacturers’ Catalog No. RC9REC or RC9REC-25.
