What is the main purpose of grounding and bonding CSST?

The main purpose of grounding and bonding CSST (Corrugated Stainless Steel Tubing) is to reduce the likelihood of electrical arcing due to lightning. CSST is often used in residential and commercial gas distribution systems, and it is susceptible to damage from electrical surges, particularly those caused by lightning strikes.

Grounding provides a path for electrical current to flow safely into the ground, minimizing the risk of shock and reducing the potential for arcing, which can ignite gas leaks or cause explosions. Bonding connects the metal components of the CSST system to ensure they are at the same electrical potential, further mitigating the risks associated with electrical faults and lightning strikes. By implementing proper grounding and bonding practices, safety is significantly enhanced, protecting both the structure and its occupants.
