What is the maximum length of an electrical bonding jumper for a corrugated stainless-steel tubing (CSST) gas piping system?

The maximum length of an electrical bonding jumper for a corrugated stainless-steel tubing (CSST) gas piping system is indeed 75 feet. This specification helps to ensure that any electrical potential that may build up on the gas piping system can be effectively managed and diverted to ground, thus minimizing the risk of electrical arcing or ignition when the system is in operation.

When installing electrical bonding for CSST, the length restriction is critical because longer bonding jumpers may lead to increased resistance and inefficient grounding. A jumper that exceeds this limit could potentially fail to provide adequate protection in the event of a fault, leading to safety hazards. Therefore, adhering to the 75-foot maximum ensures that the bonding jumper is effective while complying with safety codes or standards that govern gas piping installations.

Understanding the importance of bonding in CSST systems helps in preventing electrical hazards, ensuring that all installations are safe and compliant with regulations.
