Question: The NEC requires and intersystem bonding terminal per 250.94. Can I use that terminal bar to run a #6 to the gas meter to comply with CSST requirments for bonding or is it required to be a seperate wire?Second, can I tap the #6 to the water meter to go to bond to the gas meter? The water line coming in is copper so it is more of a grounding electrode then a bonding point if my understaning is correct.Third question is if I run a #6 to a phone board for a bussines in emt is it required to be bonded on both ends of the pipe same as if it was a GEC?In advance thanks for any input.
Q1: Using Intersystem Bonding Terminal for CSST Bonding
Yes, you can use the intersystem bonding terminal required by 250.94 for bonding CSST. This terminal is intended to provide a common bonding point for all metal piping systems and the electrical service.
Q2: Tapping #6 Wire for Water Meter Bonding
No, you cannot tap the #6 wire to the water meter to bond the gas meter. 250.104 requires that a grounding electrode conductor be connected to the gas meter piping separately, unless the water pipe is used as a grounding electrode as permitted by 250.52(A)(1) or (2).
Q3: Bonding #6 Wire in EMT to Phone Board
Yes, the #6 wire in EMT used to connect to a phone board for a business must be bonded on both ends of the pipe. This is because the EMT is considered a grounding electrode conductor, and 250.118 requires bonding of grounding electrode conductors at both ends. Flag for review
