Connection reliability is critical to the long-term integrity of a grounding and bonding system. Traditional compression grounding systems offer installation efficiencies over exothermic welding systems and are compliant with IEEE Std. 837.
The Institute of Electrical and Electronics Engineers (IEEE) developed this standard as a means of qualifying permanently installed grounding connectors. However, under certain circumstances such as installations that are subject to corrosive forces or repeated freeze-thaw cycles, the reliability of compression grounding systems is often questioned.
If a grounding system is to last, the issues that put it in danger of failing must be identified and addressed. Risks to ground connectors include:
