a.Bond the CSST tubing wall at any convenient corrugation with a small wire
b.Attach the bonding clamp to a rigid pipe component or a CSST fitting, using a jumper at least No. 6 AWG copper, connected to the grounding electrode system
c.No bonding connection is ever needed on CSST
d.Use the gas as the grounding path
Giải thích
CSST bonding is made to a rigid metallic pipe segment or a CSST fitting, not to the thin corrugated tube wall, using a listed clamp and a jumper of at least No. 6 AWG copper connected to the building grounding electrode system. This diverts electrical energy safely and reduces arc-perforation risk from lightning. Always follow the CSST manufacturer's bonding instructions and the electrical code.
