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
wire ends. Refer to Table 3.10
