One GEC to all electrodes

[GerryB]

Well, for people who consider that to not be a violation of 250.6 I will just reiterate my disagreement. (Mind you, I know that sometimes there is objectionable current on water pipes between houses, but that's something people don't really have knowledge or control of if they comply with using the water pipe as an electrode, so it is what it is.)

If you're complying with 250.50, there's generally no reason to run multiple GECs, especially with a single service disconnecting means.

Here's my concise response to the OP's post:



Not only can you, but you should. You're more likely violating code and good grounding practices if you do it some other way.

I can tell how things have evolved if you will in my area here. Older residential services you will the ground going to the water meter before the meter and nothing else. Next came one ground rod, then two, always understood both being separate would go to the first means of disconnect. Maybe around the same time as the second ground rod the water main started to be jumped out. Add some new confusion with gas pipe bonding, but SOP around here for say a 200 amp service would be #4 to the water main and #6 out to the rods.

Not required to be continuous, just bonded together.

Just to update, the installation passed inspection. From the meter/main to each side of the water meter then through the basement wall outside to each ground rod with one continuous conductor.
