If you install at Ta 50°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 50°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.
