TC TC-ER Certificate

UL (Underwriters Laboratories) is a leading global safety certification organization that develops and tests standards for a wide range of products and systems. The UL Standard TC-ER certification specifically applies to Tray Cables that are used in industrial, commercial, and residential wiring, including for photovoltaic systems.

The “TC-ER” designation stands for Tray Cable - Exposed Run, and it refers to cables that are designed to be run exposed (without additional protective coverings or enclosures) and are often installed in cable trays or other direct wiring systems. UL Standard TC-ER cables must meet strict safety and performance requirements to handle the voltage and environmental stresses present in renewable energy systems like PV installations.

UL certification ensures that cables meet the requirements for:

Electrical safety under normal and fault conditions

Mechanical strength to withstand wear and tear, including in high-traffic environments or in systems exposed to extreme conditions

Environmental durability to resist moisture, chemicals, temperature fluctuations, and other elements found in both indoor and outdoor installations

When you use UL Standard TC-ER cables, you can be confident that your photovoltaic system will maintain high operational standards while meeting regulatory compliance and safety guidelines.
