NOTE:
1. If you install at Ta 45°C environment, select copper wire with voltage rating of 600 V and temperature
resistance of 75°C or 90°C
2. If you install at Ta 45°C above environment, select copper wire with voltage rating of 600 V and temperature
resistance of 90°C or above.
3. 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.
4. Do not reduce the wire gauge when using higher temperature wire.
