■ Wire Size and Torque Specifications
WARNING! Fire hazard. Tighten all terminal screws to the specified tightening torque. Loose electrical connections could result in
death or serious injury by fire due to overheating of electrical connections. Improperly tightened terminal screws can also cause
erroneous equipment operation.
Select appropriate wire type and gauges from Table 3.8 . For simpler and more reliable wiring, use crimp ferrules on the
wire ends. Refer to Table 3.9 for ferrule terminal types and sizes.
