UL 1277 XHHW/CPE Type TC Control Cable 600V
UL 1277 XHHW/CPE Type TC Control Cable is a compact, flame-retardant 600V multicore control cable built with XHHW-2 copper conductors, FRXLPE insulation and a CPE outer jacket. It is intended for industrial power and control circuits where Type TC tray-cable installation, moisture resistance and outdoor durability are required.
PRODUCT OVERVIEW
The cable combines stranded bare annealed copper conductors with flame-retardant and moisture-resistant FRXLPE insulation and a flame-retardant, moisture- and sunlight-resistant CPE jacket. The listed conductor sizes are AWG 14, 12 and 10, and the product is rated 600V for wet or dry locations at temperatures up to 90°C.
Primary installation environments include cable trays, raceways and outdoor messenger-supported routes. The product is also listed for direct burial, Class 1, Division 2 hazardous locations and Class 1 control circuits. Constructions with three or more conductors are identified as suitable for exposed runs (TC-ER) in the supplied product data.

TYPE TC VS TC-ER
Type TC identifies the tray-cable product category. TC-ER adds an exposed-run application for qualifying constructions outside the tray under the applicable installation rules. For this product family, the supplied data states that constructions with three or more conductors are listed for exposed runs. Where TC-ER is required, confirm the cable marking and listing for the exact AWG/core construction being ordered.
PRODUCT APPLICATIONS
- Industrial power and control circuits requiring compact flame-retardant cable.
- Cable trays and raceways.
- Outdoor messenger-supported installations.
- Direct-burial routes where the required cable marking is confirmed.
- Wet or dry industrial locations up to the listed 90°C rating.
- Class 1, Division 2 hazardous-location projects as stated in the product data.

From Production to Delivery
The following schedule reproduces the listed XHHW/CPE Type TC cable dimensions and approximate weights for AWG 14, AWG 12 and AWG 10 constructions.
Production
Stranded bare annealed copper conductors are insulated with FRXLPE, assembled into the required multicore configuration and finished with the specified CPE outer jacket.
Inspection
Inspection focuses on conductor construction, insulation and jacket condition, finished dimensions, cable weight, marking and the project-specific electrical / flame-performance documents required for approval.
Packaging
Finished cable is wound on suitable reels or drums according to cable size, weight and ordered length. Product identification can include standard reference, AWG size, core count, length and project reference.
Shipping
Before shipment, cable identification, packing and requested technical documents are checked against the order. Where fire-performance documentation is required, the applicable test report or certification package should be agreed before production.
Frequently Asked Questions
What products do you supply for the power cable industry?
We provide a wide range of cable materials and electrical products, including aluminum conductors, aluminum rods, aluminum wires, overhead conductors, medium and low voltage power cables, cable insulation materials, filling materials, shielding materials, and cable manufacturing consumables.We provide customized solutions according to different cable manufacturing requirements.
What is the practical difference between Type TC and TC-ER for this cable?
Type TC is the tray-cable product designation, while TC-ER is relevant when qualifying cable is permitted to leave the tray for an exposed run under the applicable installation rules. This product data states that constructions with three or more conductors are listed for exposed runs. For a project, confirm that the exact ordered construction carries the required TC-ER marking.
Can this cable be installed outdoors or directly buried?
Yes, those applications are stated for this product family. The CPE jacket is described as moisture- and sunlight-resistant, and the product data also lists direct burial. For formal approval, the actual cable marking/listing should be checked for the required outdoor, wet-location and direct-burial ratings.
Why is CPE used for the standard outer jacket?
The listed CPE jacket is flame retardant and also described as moisture- and sunlight-resistant, which fits the industrial and outdoor installation focus of this Type TC cable. PVC or LSOH can be supplied on request, but a jacket-material change should be reviewed against the project’s flame, environmental and approval requirements.
Is this cable suitable for Class 1, Division 2 hazardous locations?
The product data lists Class 1, Division 2 use. Hazardous-location compliance also depends on the wiring method, fittings, seals, cable marking and applicable electrical code, so the complete installation should be reviewed rather than relying on the cable name alone.
How should I choose the AWG size and number of cores?
Start with the electrical design, number of control functions and spare-core requirement, then select the required AWG size. After electrical selection, check the finished diameter and weight because these affect tray loading, raceway fill, pulling and termination space.
