Cable management
Follow all local codes for cable management. As a general rule, you can fill a cable conduit to a maximum of
60% of its capacity. You must maintain 40% free space. A variety of factors will determine how many cables
you can run into the dome. Capacity limitations include:
• number of cables
• size of the cables
• use of single-conductor or multiple-conductor cable
• use of a junction box
Figure 3 provides an illustration of the cable capacity of three typical applications. It is important to note that
all cables of the same gauge are not of the same diameter. Manufacturer, shielding, and rating affect the actual
diameter of cables of the same gauge. GE leaves the selection of the appropriate cable to the discretion of the
installer who is working with the local codes of the installation site.
