 If you install at Ta 40°C (with conduit box) / 50°C (without conduit box) above environment, s
elect
copper wire with voltage rating of 600 V and temperature resistance of 90°C or above.
 If you install at Ta 40°C (with conduit box) / 50°C (without conduit box)
environment, select copper
wire with voltage rating of 600 V and temperature resistance of 75°C or 90°C.
 For UL installation compliance, use copper wires when installing.
The wire gauge is based on temperature resistance of 75°C, in
accordance with UL requirements and
recommendations. Do not reduce the wire gauge when using high-temperature resistant wires.
