For external power wiring requirements, including the minimum AWG size of external wiring, see Table 3-3.
Wire sizes listed are for copper wiring only.
The power wiring terminals are pressure terminations, UL and CSA rated at 90°C. See Table 3-4 for external
input power cable terminations and Table 3-5 for external output power cable terminations.
Figure 4-11 and Figure 4-12 show the IAC-D input power terminal locations and detail.
