If you install at Ta 50°C environment, please select copper wire with voltage rating 600V and
temperature resistant at 75°C or 90°C.

If you install at Ta 50°C above environment, please select copper wire with voltage rating 600V and
temperature resistant at 90°C or above.

For UL installation compliant, please use copper wires for installation, the wire gauge is based on
temperature resistant at 75°C which is requested and recommended from UL. Do not reduce the
wire gauge when using higher temperature wire.
