UL ® Conditions of Acceptability
Applications must be tested as described below for specific wire
insulation or specific wire gauge sizes. Tests shall be performed in
the end application under worst case operating conditions.
Test Procedure
A. Monitor temperatures of terminals, using thermocouples between the
ring terminal and connectors L1, L2 or L3. The temperature must not
exceed 95°C (203°F).
B. Monitor temperatures of wire insulation, using a thermocouple located
three inches from the connector. The temperature must not exceed
the insulation rating of the wire.
*30A is maximum rating when operating above 240VÅ(ac).
Warning: Thermocouples attached to terminals will be at load voltage
potential, measurements need to be taken with isolated equipment or
isolate the sensor from terminal with suitable insulation.
