Information on laying tray cables for exposed run (TC-ER)
The procedure for using conduits is described in this section. Instead of conduits, you can also
use tray cables for exposed run (TC-ER).
• When using tray cables for exposed run (TC-ER), select suitable cable glands and
attach to the enclosure opening instead of the conduit. When doing so, ensure that the
enclosure opening is sealed and no moisture can enter.
Requirement:
☐ All electrical installations must be carried out in accordance with the locally applicable
electrical standards and the National Electrical Code
