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.

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.
