Section 110.14(D) Installation

Section 110.14(D) Installation

(D) Installation. Where a tightening torque is indicated as a numeric value on equipment or in installation instructions provided by the manufacturer, a calibrated torque tool shall be used to achieve the indicated torque value, unless the equipment manufacturer has provided installation instructions for an alternative method of achieving the required torque.

Analysis of the Change

This new requirement will mandate the installer of mechanical connectors and lugs that include a numerical torque value to use a calibrated torque tool for installation. Alternative means are identified for connectors that will not require a torque tool such as connectors with sheer bolts that are designed to sheer at a manufacturer’s designed torque value.

Products

Blackburn and Homac electrical connectors.
