What is the minimum pull test requirement for fittings used in lightning protection systems?

The minimum pull test requirement for fittings used in lightning protection systems is 200 lbs. This requirement is established to ensure the reliability and integrity of the connections in lightning protection systems, as these systems play a crucial role in safeguarding structures from lightning strikes.

Fittings must be capable of enduring significant forces without failing, and the 200 lbs pull test helps to verify that the connections can withstand the mechanical stresses that may occur during a lightning event. Ensuring that fittings meet this standard is essential for the overall effectiveness of the lightning protection system, which must securely channel the electrical energy from a lightning strike into the ground without risking damage to the structure it protects.
