Chapter 5 Main Circuit Terminals MS300 Frame B Figure 5-9 If you install at Ta 50 ° C above environment, use copper wires that have a voltage rating of 600 V and are temperature resistant to 90 ° C or above. If you install at Ta 50 ° C environment, use copper wires that have a voltage rating of 600 V and are temperature resistant to 75 ° C or 90 ° C. To be UL installation compliant, you must 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.
