INSTALLATION INSTRUCTIONS

Installation Instruction No.: 1 006 179 – September 2006

Wiremold / Legrand electrical systems conform to and should be
properly grounded in compliance with requirements of the current
National Electrical Code or codes administered by local authorities.

All electrical products may present a possible shock or fire
hazard if improperly installed or used. Wiremold / Legrand electrical
products may bear the mark as UL Listed and/or Classified and should
be installed in conformance with current local and/or the National
Electrical Code.

IMPORTANT: Please read all instructions

before beginning.

BEFORE CONCRETE POUR:

NOTE: Box is supplied with tunnel bracket, tunnel blocks

and device mounting brackets installed. If the
same service is to be used in both compartments,
it will be necessary to remove one or both of the
tunnel blocks to allow for pass-through of the
service wiring. The tunnel blocks are accessible
by removing the tunnel support. The installer may
do this either pre- or post-pour.

Step 1. Determine box location and conduit layout. Remove

box cover and desired knockouts and attach
appropriate conduit adapters, (not supplied by
Wiremold) to steel base.

Step 2. Re-attach box cover to base with (2) #8-32 x 1/2" long

screws provided.

Step 3. Adjust height of box so that the top of the black

trim ring is approximately 1/16" below the concrete
screed line.

Step 4. Secure the box to the floor using wire or other

fasteners through the holes provided in the top
cover. Once positioned, connect conduit to adapters
previously attached to box.

Step 5. Insert mud cap into top opening and press down

firmly to secure. Box is now ready for pour.

WARNING: Pour concrete to 1/16” (1.6 mm) above box

housing. Pours of 1/4” (6.4 mm) or more
over box housing will make it difficult to
break out the mud cap and cause excessive
concrete spalling.

numbers, installed as shown: RFB2DP, RFB2GFI.

Step 6. Locate box and chip away concrete located in mud

cap. Remove mud cap, and clean out any debris from
inside of box. If concrete does not break cleanly around
preset, the activation might not be properly supported.
The concrete edges around the top opening of the
installed box must be smooth and level for the proper
fit of the FloorPort Activations. Remove device
brackets, and the tunnel block(s) if required to provide
for the same service in both compartments. To access
the tunnel blocks, remove the tunnel support and then
re-install after removing the required block(s).

Step 7. Wire devices (not supplied by Wiremold), making sure

that any ground leads are properly connected to
ground screws. Attach the receptacle to the receptacle
mounting bracket using the #6-32 screw provided.
Secure the receptacle to the receptacle mounting
bracket with (2) additional screws and nuts, (not
provided). Attach the receptacle mounting bracket(s) to
the base with the (2) #8-32 mounting screws provided.

Step 8. Complete procedure by installing a Wiremold FloorPort

Activation, (sold separately), using the installation
instructions provided with that unit.
