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 list-
ed, 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.
