Raceway
The term “Raceway” is used to refer to several items in cable installation. A
raceway of any type is a channel, tray, or platform along which cable is laid. Most
raceways are differentiated from conduits in the construction of each; where a
conduit is a cylinder that is closed on all sides and open at both ends, raceway is
typically open on one side along its entire length.
Floor raceway is a channel or trench set into the floor of a facility that cable may
be placed in. Floor raceway usually is a characteristic of a facility’s construction
that cannot be added after the facility has been completed.
Another common type of raceway is the tray-type raceway. Open on the top, the
tray-type raceway is often run along walls like a series of D-rings or used in open
areas, such as the space above suspended ceilings, to force cabling to follow a
specific path, routing it around sources of potential physical damage or electrical
noise.

Labeling Tape
All cables in an installation should be labeled. The addition of detailed labels to
cabling in an installation makes the process of installing, troubleshooting,
repairing, replacing, or expanding the facility cabling much easier. Cable labeling
tape is a markable tape (it may be written upon) with strong adhesive. When
labeling cables, keep the installation requirements of the cable run in mind. If a
cable which you are labeling needs to be pulled through a conduit or innerduct,
large, loose labels may bind or be pulled off during installation.
