◆ Wire Selection
Select the correct wires for main circuit wiring.
Refer to Main Circuit Wire Gauges and Tightening Torques (CE-compliance) on page 149 for wire gauges and
tightening torques as specified by European standards.
Refer to Main Circuit Wire Gauges and Tightening Torques (UL Compliance) on page 167 for wire gauges and
tightening torques as specified by UL standards.
These tables use icons in Table 3.2 to show the shapes of the screw heads.
