Under ground water pipe contiunity

[hhsting]

I have underground metal water pipe as grounding electrode. It has water meter/filter device right where it enters little beyond 5 feet like 6 feet. I am required to provide bonding jumper per NEC 2014 section 250.53(D)(1).

I did research I would imagine this is equipment bonding jumper right at the service disconnect. However not sure. Would it be supply side bonding jumper.

Which table one uses to size the bonding jumper and where is it in code?

Yes supply side, 10 feet or more of underground water pipe "grounding electrode" NEC Table 250.66 ...If you're jumping the meter " bonding jumper" #6 cu

Which table you used? Not sure how you got #6 cu. i have incoming service conductor 13 sets 500 kcmil Al into 4000A service disco.

That 6 is only for if you're jumping the meter .If you can get on the other side of it the then do so . I'll try to find it

I am jumping the meter and trying to find code section on which table to use to size the jumper.

The jumper is to maintain continuity to water pipe if meter is removed, jumper would be same size as GEC.

Once you exceed 1750 kcmil in service conductors, the GEC is 3/0 Cu.. the "jumper" see post #6
