What is the difference between TC and TC-er cable?
TC-ER cable refers to exposed run or ER-rated tray cable. TC-ER cables are out in the open instead of being buried underground where they are protected from wear and tear. Tray cables with an ER rating can be used up to 50 feet outside the tray without the need for additional armor if given proper support.
Can you direct bury tray cable?
XLP/XPTC tray cable can be installed in free air, in raceways, or direct burial. It can be used in rough environments hence approved for wet or dry locations as well as Class 1 Division 2 hazardous locations.
Can tray cable be run exposed?
To be approved for this rating, tray cables must pass additional crush and impact tests. Once a tray cable is marked with this rating it is deemed durable enough to be used as exposed wiring. This means that the cable does not require armoring and that it may be installed outside of the conduit or another raceway.
Can a ER rated cable be used in an exposed run?
The NEC has several additional requirements that must also be met before ER-rated cables can be used in exposed runs. These include: Exposed runs are permitted only in industrial establishments where the conditions of maintenance and supervision ensure that qualified persons service the installation.
Can a ER cable extend outside the tray?
Cables with an ER rating, on the other hand, can extend outside the tray if given adequate protection and support. Thus, in some applications, the use of ER-rated cables can eliminate the cost of installing conduit between the tray and an electrical device or the cost of using armored cable.
What’s the difference between PLTC ER and commercial grade cable?
Table 1: Feature comparison chart for cable types from PLTC-ER to commercial-grade cables. Power Limited Tray Cable Exposed Run (PLTC ER), also called “open wire” cable, is an industrial-grade solution that can be installed without the use of a conduit or a tray.
