3.) Proposal:
Revise 250.104(A) as follows:
Revise 250.104(A)(1) as follows:(A) Metal Water Piping. Where metal water piping systems do not meet the criteria for a grounding electrode as described in 250.52(A)(1), interior metal piping shall be bonded as required in (A)(1), (A)(2), or (A)(3) of this section. The bonding jumpers shall be installed in accordance with 250.64(A),(B), and (E). The points of attachment for the bonding jumpers shall be accessible.
4.) Substantiation: Under the 2005 NEC, interior metal water piping that does not qualify as a grounding electrode, extending ten feet beyond the structure, is still required to be sized for the service fault current that could not possibly energize the piping. Since the interior water piping would not be a grounding elecrode, there is no reason to bond to the service disconnecting means as currently required.(1) General. Interior metal water piping system(s) shall be bonded to any accessible point on the equipment bonding system. The bonding jumper shall be sized in accordance with 250.122, using the rating of the circuit that is likely to energize the piping system. If no such circuit exists, the bonding jumper shall not be smaller than 8 AWG copper.
