BICSI recommends tests be done to evaluate bonding connection between telecom busbars and AC grounding.

BICSI emphasizes keeping telecom grounding and the building’s AC grounding at the same potential, so a solid bond between the telecom bonding busbars and the AC grounding system must be verified. Testing this connection ensures there is a continuous, low-impedance path for fault currents and surges, preventing dangerous voltage differences between telecom equipment and building metalwork. A measured bond with low resistance confirms the bond exists and will perform under fault or lightning conditions, protecting personnel and equipment. This requirement applies to all installations, not just outdoor or high-voltage cases, because the safety and reliability benefits come from a reliable, common ground path everywhere.
