Training Circular TC 6-02.6 (TC 11-6) Grounding Techniques for Tactical Equipment and Systems November 2017This training circular is a guide to proper earth grounding methods and procedures for use with tactical systems. It describes different earth grounding systems and provides guidance on the proper methods for their installation. Earth grounding helps to protect personnel and equipment from electrical faults and power surges. Earth grounding also helps reduce circuit noise and other transmission interference that can degrade communications-electronics system performance (CECOM TR 98-6). The instructions contained in this circular are designed to supplement information not often found in technical manuals. It will help in setting up effective and safe earth grounding systems for tactical equipment, systems, and shelters. The procedures outlined in this training circular can assist in solving grounding problems which may be encountered. For detailed grounding procedures, consult the specific manual on the tactical equipment or systems being operated or installed. Failure to ground equipment or improper grounding can lead to serious injury or death. The equipment is also subject to catastrophic failure from electricity surges. Improper grounding can lead to burned-out circuit cards or complete destruction of a piece of equipment or the entire system may become nonmission capable.
