For UL installation compliance, select copper wires with voltage rating of 600V and temperature
resistance of 75°C.
Choose terminal wire size as Figure 4-12 shows.
Use insulated heat shrink tubing that is resistant to at least 600V to comply with UL and CSA
regulations (600 V, YDPU2), as Figure 4-13 shows.
If you install at Ta 50°C environment, use copper wires with voltage rating of 600V and
temperature resistance of 75°C or 90°C.
If you install at Ta 50°C above environment, use copper wires with voltage rating of 600V and
temperature resistance of 90°C or above.
To be UL installation compliant, you must 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 wire.
