Eliminate Earth Loops - Point 5 of Six Point Plan

Equipotential bonding is a very important measure to reduce equipment damage and life hazard for any site to be protected. Equipotential is achieved by means of bonding all circuits and conductors in a manner that reduces potential differences between elements of the lighting protection system, the metal framework of the structure, metal installation, conductive parts and electrical and telecommunications installations at the facility.

In some fasilities however, for the purposes of minimizing "noise" and for other reasons, separate grounds may be install for lighting protection, main power, computer and communications equipment. Although this may safe under normal conditions, large potential differences can occur under "fault" or "transient" conditions. ERICO's TECs can solve these problems by remaining in "open circuit" under normal operation, but forming a "closed" circuit under transient conditions.
