UL1277 TC-ER Xhhw-2 3c 12awg Cable

● TC-ER (Tray Cable – Exposed Run)
TC stands for tray cable, suitable for placement in cable trays.

ER stands for "exposed run," meaning the cable can be run outside the tray for a certain distance without additional protection.

●XHHW-2: The conductor insulation type used in the cable.
XHHW is an insulation type used in high-heat and high-humidity conditions, made of cross-linked polyethylene (XLPE).
XHHW-2 designates it as suitable for use in wet/dry environments up to 90°C and offers excellent heat and moisture resistance.

● 3C：Indicates the cable contains three conductors/WC57 Method 4.

● 12AWG：Indicates the conductor size is 12 American Wire Gauge.

FAQ

Q: Is the conductor of TC-ER XHHW-2 3C 12AWG cable copper or aluminum?

A: To ensure lower resistance, higher conductivity, and greater flexibility, most manufacturers use copper as the conductor material. While some cable models may use aluminum, aluminum is less common in smaller sizes like 12AWG. Therefore, the TC-ER XHHW-2 3C 12AWG cable typically uses copper. Please refer to the specific product specification for confirmation.

Q: What UL certifications does the TC-ER XHHW-2 3C 12AWG cable have?

A: TC-ER XHHW-2 3C 12AWG cable is typically certified by the following UL (Underwriters Laboratories) certifications:

UL1277: Suitable for power and control tray cables, approved for use in wet and dry locations, direct burial, or in trays.

UL44 Type XHHW-2: Designated with cross-linked polyethylene insulation, heat-resistant up to 90°C, and rated voltage 600V.

Q: Is the TC-ER XHHW-2 3C 12AWG cable suitable for outdoor or direct burial installations?

A: TC-ER XHHW-2 3C 12AWG cable is typically suitable for outdoor and direct burial installations. This cable features XHHW-2 insulation, which offers excellent resistance to heat, moisture, and UV rays, making it well-suited for outdoor environments. The TC-ER (Tray Cable – Exposed Run) rating indicates that it can be installed exposed without the need for additional conduit and provides some mechanical protection. Most of these cables meet the UL 1277 standard for direct burial use. However, because outer jacket material and construction may vary between manufacturers, the specific product's technical data sheet and UL filing should be consulted to ensure the cable is certified for direct burial installation. In environments with moisture, corrosive conditions, or high mechanical stress, additional protective measures are recommended to extend the lifespan.
