If you install at Ta 40 °C environment, select copper wire with voltage rating of 600 V and

temperature resistance of 75 °C or 90 °C.
If you install at Ta 40 °C above environment, select copper wire with voltage rating of 600 V and

temperature resistance of 90 °C or above.
For UL installation compliance, use copper wires when installing. The wire gauge is based on a

temperature resistance of 75 °C, in accordance with UL requirements and recommendations. Do not
reduce the wire gauge when using high-temperature resistant wires.
