INSTALLATION INSTRUCTIONS
Installation Instruction No.: INST014 R2 – Updated April 2005
NOTE:* 20% cable fill is calculated to approximate reduction in cable capacity due to connectors mounted within raceway and fittings that may restrict
cross sectional area.
** 40% cable fill is the maximum designed cable fill base on a proposed revision to TIA/EIA 569-A.
Wiremold Electrical Systems conform with, and should be installed and
properly grounded in compliance with requirement of the current
National Electrical Code or codes administered by local authorities.
All electrical products may represent a possible shock or fire hazard
if improperly installed or used. Wiremold electrical products are UL listed, made for interior use and should be installed by qualified
electrical people in conformance with current local and/or the
National Electrical Code.
Note: Raceway may be configured in single or multiple channels
to accommodate power or communications wiring.

AL3300B BASE
AL3301 COUPLING
AL3309 GROUND CLAMP
AL3300 SYSTEM PRODUCT APPLICATION
At AL3300B base section butt joints, slide AL3301 Coupling
into first base section. Mount next base to surface. Center
coupling on joint. Tighten locking screws.
To attach AL3300B Series base sections to mounting surface.
Drill 9/32" holes in the base (approx. 48" o.c.). Fasten base
with #8 flat head screws.
1. Provide electrical feed through 1/2" or 3/4" trade size
K.O.’s in at AL3310B1 end.
2. Attach base section to mounting surface by drilling 9/32"
holes in base then fastening with #8 flat head.
3. Secure conductors in place with AL3300WC Wire Clips.
4. Join additional raceway sections with AL3301 Coupling.
5. Close end with either AL3310B or AL3310B1 End Fitting.
6. Snap cover into base to complete installation.
Position AL3309 Ground clamp into rib in AL3300B raceway
Base. Tighten locking screw. Attach ground wire using
brass cup washer and green hex nut to ground lug.
AL3300 SERIES DEVICE PLATES
AL3300D SERIES DIVIDER
For AL3346 and AL3356 Series Device Plates, install wiring
to devices as required. Attach device to plate using #6
screws and "keep" nuts (provided). Snap device plate
onto AL3300B raceway base.
Position AL3300D Divider into AL3300B raceway base as
shown. See cross sections below and refer to wire fill charts.
