IMPORTANT – PLEASE READ ALL INSTRUCTIONS BEFORE BEGINNING.
Products Covered: RC3S, RC3C20, RC3C15, RC3A20A, RC3CRT, RC3ART, and RC3G
Step 1: Core drilling of hole. Step 2: Insertion of Poke-Thru into Core-Drilled Hole.
Insert prewired assembly into hole and push down
until disposable cover plate or finish ring completely
seats onto concrete.
NOTE: Orientation of receptacle before
insertion is critical. Once installed,
the poke-thru cannot be rotated
for adjustment.
IMPORTANT: With RC3S the finish ring
and slide cover assembly
are packaged and sold
separately. To maintain
fire rating of device,
finish ring and slide
cover must
be installed.
CAUTION: Holes shall be spaced a minimum of 2' [610mm]
on center and not more than one hole per each
65 sq. ft. [5.9 sq.m] of floor area in each span.
Step 3: Remove Disposable Cover Plate (RC3S): Step 4: Install Finish Ring:
Using four #6-32 screws, install ring and push
down so that ring compresses floor covering.

The RC3 Series Poke-Thru Device is UL Listed and Classified to U.S. and Canadian safety standards to the following conditions:
The RC3S Poke-Thru Stem with the RC3S Service Head Fitting, the RC3A factory assembled poke-thru device, and the RC3RAP1, RC3RAP2
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 the service fitting or the abandonment fitting 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. [5.9 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 4" [102mm] 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:
(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 floors only.
Replacement receptacles are limited to the following:
Pass & Seymour 5252, 5352, BR15, IG6200, and IG6300, or Leviton 5262, 5362 only.
