complete system which consists of standard construction cable protectors are used to protect against vehicular traffic,
components that can easily be installed and wired. such as light and heavy trucks and fork lifts.
For more permanent installations, a service trench is
installed as shown in Figure 10-82. To prevent bending, the
Wire Duct cover plate should be selected to support, at least, twice the
highest anticipated load.
Wire duct is free standing ducting specifically designed to
support wiring. These systems are commonly found on large
equipment and in industrial environments. Figure 10-79
shows a few components of a typical wire duct system.

Wire Guide

Wire guide is a convenient method to provide ducting for the Tread Plate
inside of control cabinets. The guides are plastic trays with an
array of vertical arms that make up the sides. Wires can be Concrete Floor
passed easily through the sides and down the guide. After
wiring is complete, the guide has a snap-on top which pro- Trench
vides a very clean appearance. Figure 10-80 shows a typical
length of commercial wire guide.

Cable Protectors

Cable protectors are generally deployed anywhere a service
cable must be routed across a heavy traffic area. Figure 10-81
shows two common cable protectors. Light duty protectors
are made from molded or extruded plastic or rubber. They are Figure 10-82 Service Trench
