bonding jumper or GEC #200530 04/05/11 11:26 PM

A GEC from the panel terminates to the water pipe, then a bonding jumper from the water pipe terminates on the ground rod.
One of my colleague says it is a violation because it has to be one continuous piece from the panel to the water pipe then to the ground rod.

I say the only portion that has to be continuous is the GEC not the bonding jumper that is to the ground rod.

i will try to post the picture.

The GEC need only be continuous between the panel and the first grounding electrode.

Code language can lead you to your friends' view, but the matter is addressed in Soares. Call it another example of bad grammar on the part of the NEC.

Reno,

Another section of "Bad Grammar" in the NEC IMHO is under 680 for "Bonding". Where the bonding conductor must be "Continuous without splice", but you can land 2 pieces of bonding wire under a proper bonding lug strip. Like in a deck box, you have the #8 from the light into a bonding lug, and on another bonding lug you have the #16 ground wire from the light and the #12 grounding wire from the circuit that feeds the light.

A lot of the lugs that I see for conduits and pipes are designed so that you can lay the conductor in the lug and tighten it without having to cut the wire.

Ghost,

I have seen those kinds of bonding bushings too. They are fine and acceptable. I was referring in my post about using approved lugs to connect "Bond" wires to and yet it doesn't mean "Without Splice". Some EC's go to great extent to run wires without splice but fail to use these lugs that are approved for use.

My only problem with landing on the rod first is what size wire is that? wink

it is #4 to the water pipe first then a separate piece of #4 goes to the ground rod.

That is exactly right the way you described it in the OP.
I thought I heard you went to the rod first, Even then it would be OK as long as you had the #4 or whatever 250.66 calls (to bond the water pipe)
The GEC is the first connection to an electrode. everything is a bonding jumper.

From the handbook
