Electrical Bonding
• Bonding/grounding clamp specications: conductors are to be no smaller than 6
AWG. Bonding clamps are to be listed to UL 467, and be attached in accordance
with the National Electric Code (NEC) and the listing of the clamp. The attachment
point for the bonding conductor is to be accessible. This bond is in addition to any
bonding requirements as specied by local codes. Note that the National Fuel Gas
Code (NFGC) limits the length of the bonding conductor to 75-feet. The bonding
connector must be installed and protected in accordance with NEC and NFPA 70.
• Attachment between the CSST gas piping system and the bonding clamp must be
made by connecting to a HOME-FLEX® brass tting (Figure 4.29), or any rigid pipe
between the rst CSST tting in the system and the meter (Figure 4.30). Under no
circumstance is HOME-FLEX® CSST tubing to be used as the attachment point for
the bonding conductor.
