A tightening torque requirement may be included in the 2017 NEC. Code Making Panel 1 has developed a first revision that would require a calibrated torque tool to be used to achieve the indicated torque value, indicated as a numeric value on equipment or in the installation instructions provided by the manufacturer, unless the equipment manufacturer has provided installation instructions for an alternative method of achieving the required torque. Use of proper torque tools is essential to verify that terminations are properly made and the equipment will function properly
throughout its life cycle. Testing has shown that installers use the wrong torque values in up to 75% of installations unless a torque measuring tool is used.
