What is a Tray Cable?

A tray cable, or TC as it is commonly referred to, is a multi-conductor cable that is used in industrial environments, designed for power and signal transmission. These cables are often installed through ducts, wire trays, and conduit. Tray cables are often found in an industrial environment which at times can be harsh due to exposure to high temperatures and different chemicals. in some applications, tray cables are installed in buildings and are required to be plenum rated. Plenum rated cables are cables that comply with flammability and smoke specifications set forth by the National Electrical Code (NEC). Tray cables are primarily UL rated, can be shielded or unshielded, and are offered in 300V and 600V. Another type of tray cable is PLTC that stands for Power Limited Tray Cable. PLTC is only rated up to 300V.

Terminology Notes

There are various terms used in the wire and cable industry related to this type of cable. They include:

  • PLTC, which stands for Power Limited Tray Cable. These cables are typically used for applications that have power limited circuits such as an alarm system.
  • VNTC, which stands for Vinyl Nylon Tray Cable. A VNTC cable is constructed using THHN or TFFN conductors with a PVC outer jacket. These cables are flame retardant.
  • TC-ER, which stands for Tray Cable – Exposed Run. These cables are used when they cannot be installed in a closed environment like conduit or a tray.
  • TC-ER-HL, which stands for Tray Cable – Exposed Run in a Hazardous Location. Similar to the TC-ER, but in an environment that is considered extreme.
  • Plenum rated, which refers to the flammability and smoke specifications of a cable.

Tray cable and instrumentation cable are very similar and are sometimes used interchangeably.
