## XLPE/PVC tray cable construction

DEV CABLE manufactures this cable to **UL 1277 tray cable construction specifications**, using **stranded copper conductors, XLPE insulation and a PVC jacket**. It is intended for industrial power, control and equipment connection projects involving cable trays and permitted exposed runs.

Copper carries the circuit current, XLPE insulates the cores, and PVC encloses the cable. These materials alone do not establish voltage, wet/dry temperature or environmental ratings: select these for the ordered construction.

## TC-ER cable specifications: selection checklist

Use this table to prepare an enquiry, then verify the proposed model data before ordering. It describes **selection requirements, not a list of stocked configurations**.

| Selection item | What to specify and verify |
|---|---|
| Conductor size | Original AWG or mm² requirement, stranding and circuit duty. An approximate area conversion does not establish an equivalent conductor specification. |
| Cores and ground | Insulated core count; ground size/type and whether it is included. Four insulated cores and three cores plus ground are different configurations. |
| Voltage and temperature | Circuit voltage, required cable rating and wet/dry operating conditions. Confirm the ratings of the proposed construction. |
| Shielding | Circuit, interference sources and screen/termination requirements. TC-ER designation alone does not establish shielding performance. |
| Installation dimensions | Gland entry and available space; check the offered outside diameter, weight and installation bend radius. |
| Environment and jacket | Oil, sunlight, moisture and other exposure; jacket color and printing. Each required environmental property needs supporting evidence. |
| Standards and documents | Project specification, destination requirements and any mandatory marking or third-party listing requirement. Identify these in the RFQ for technical review. |
| Supply | Total length, cut lengths, packaging, destination and required delivery date. Confirm MOQ, stock and delivery terms in the quotation. |

## Selecting cable for industrial circuits

For **power connections and motor control centers**, provide load, grounding and route. Current capacity depends on conductor size, installation conditions and applicable design rules, not just the cable-family name.

For **control panels and machinery**, use the wiring diagram to define cores and identification. Specify interference and screening needs. Stranded copper alone does not establish suitability for continuous flexing, drag chains or variable-frequency-drive motor leads.

For **utilities, processing, oil and gas, mining or cement plants**, describe the actual exposure and installation area. An industry name does not establish hazardous-location, outdoor, chemical or direct-burial suitability. Export projects also need destination-specific review.

## TC vs TC-ER: marking and permitted use

TC means tray cable; ER means exposed run. The distinction matters when cable leaves the tray to connect to equipment. Ordinary TC designation alone is not permission for a TC-ER exposed run.

[UL 1277](https://www.shopulstandards.com/ProductDetail.aspx?productId=UL1277) covers power and control tray cables and exposed-run marking. Verify the ordered cable marking, applicable listing requirements, support, protection against physical damage and permitted installation method. TC-ER does not mean unrestricted installation without conduit.

The NEC is an installation code, not a product certification. Check the applicable edition and local authority requirements. A shielded control cable is not automatically a TC-ER substitute: screening and installation suitability are separate selection criteria.

## Model data and project documentation

Request technical information tied to the **quoted construction and revision**, and confirm the document scope before using it for project approval:

- Conductor, core/ground arrangement, insulation, jacket and rated voltage/temperature.
- Construction drawing, outside diameter, weight and installation bend radius.
- Required marking, conformity documents and agreed inspection scope. State any third-party listing requirement explicitly in your RFQ.

100% continuity testing does not imply dielectric, insulation-resistance or certification testing. Use model documentation for engineering decisions; gallery images do not establish model dimensions, stock or approval.

## Request a TC-ER cable quotation

Send the selection details above with your cable schedule, quantity, cut lengths, packaging preference, destination country/port and required delivery date. Include mandatory documentation requirements in the initial enquiry.

**Every finished cable length receives 100% continuity testing before shipment. We provide a technical quotation within 24 hours after receiving a complete RFQ.** The quotation deadline is not a production or delivery lead-time commitment.

## TC-ER cable purchasing FAQ

### Does the conductor count include the ground wire?

Do not assume it does. Specify the insulated core count and ground size/type separately, and identify whether ground is included in the total. Match the notation to the wiring diagram.

### How do I choose AWG and conductor count?

Use the circuit design and cable schedule. Load and installation determine sizing; the wiring diagram determines cores and grounding. Supply the original AWG or mm² requirement, not only an approximate conversion.

### Can I specify shielding for TC-ER cable?

Include the circuit, interference environment and screen termination in your RFQ. Confirm the offered shield construction and availability; neither copper stranding nor TC-ER marking guarantees screening.

### Does TC-ER mean oil resistant, sunlight resistant or direct burial rated?

No. Verify each property against the exact cable marking and documentation. Exposed-run suitability alone does not establish those ratings or hazardous-location approval.

### How do I request a TC-ER cable datasheet?

Identify the proposed construction and request its technical data and revision. Confirm document availability and scope, including drawings and any conformity documents required by the project.

### When will I receive a quotation?

Within 24 hours after we receive a complete RFQ: conductor size/count, ground, voltage, wet/dry temperature, shielding, exposure, required documents, quantity, cut lengths, packaging, destination and delivery requirement.
