Just so I'm perfectly clear on this, some of you are grounding electrical equipment based on the color of a screw???
Be afraid; be very, very afraid!

We have to pound in two ground rods here and they have to be so many feet apart. can't recall which. Also has to be grounded to water line. 3 points ground. stupid.

Grounding rod here at the meter box, 4 feet in the ground. Also ground to incoming water supply pipe from breaker box.
Grounding to water pipes, while once common, is no longer considered safe in many locales. Not only does it pose safety issues, but can also cause electrolysis to destroy plumbing components. Single point grounding via an 8 foot ground rod is preferred. Multiple grounds in a residential system can create different potentials within the electrical system and this is not a good idea, particularly for electronics and computers. This is not necessarily true in industrial installations but they utilize an interconnected "grid" system with protective devices installed for electronics and computer systems. Not an electrician but I do have considerable experience with water utility systems utilizing computerized monitoring systems. Just my .02.

They made us go to 3 ground points here several years ago. My guys always bitched when I made them beat the rods in for the electrician

Well, those who make the rules, many times, don't have a clue. LOL I suspect you might agree. In truth, one size fits all, usually fits nobody.

Gotta agree with you completely here, was just saying how they want it done here. My house has had that system in place for 60 years, with no issues to the plumbing (copper cold water side). In fact, when they installed the computerized water meters here a few years back, they made sure that the ground from the panel was completely secure. Honestly not sure how the potential is affected in my house by having two grounding points, I've never checked it.
Electrical systems are like people, every one is different. Even measuring everything doesn't always work. I've seen problems that took many hours to solve, and sometimes never did figure it out. Some work even though they are "wrong," but I've replaced many a water meter or valve that was eaten up by electrolysis, one house out of many, no telling.

You dont have to pound them in the ground.. All you need is a gallon of water!!! Peace Toolman
