Good point. I'll look for another reference re the GEC needing to be unspliced. I'm a bit off the mark with 250.24 (C). I took the 250.24(C) refence out with KZread editor. Thanks for pointing that out!

This would be great in my EKit.

Looks to me; both rods were cut off and are no longer 8 feet Making them both code violations.

Good point. But it was just a competition. So, if they would have drilled those rods down 8 feet, they would have gone through the ceiling and into the 1st floor. So it was a simulation, but they were inspected by judges.

​@@SparkyChannelmaybe you can get a hand bender and bend a back-to-back 90 on one ground rod. That way you do not have to cut it or go through your floor.

I submit that an additional configuration should be approved. Strip about 3" of insulation from the ground wire as in the left example. Bend the wire back on itself leaving a loop of bare copper. Place this loop against the copper clad ground rod and slip an acorn nut over the loop and the rod. Tighten securely. As in the left example, the ground wire is not cut and continuity is maintained if the acorn nut becomes corroded or loose. Advantage 1: No need to thread the acorn nut down from the free end of the ground wire. Advantage 2: Twice as much ground wire conductor is in contact with the ground rod. Advantage 3: An additional ground rod can be added at any time without interrupting the existing ground circuit. Advantage 4: The ground rod can be easily serviced and the acorn nut replaced if necessary without disturbing the existing ground circuit.

Folding the GEC in half and sliding the acorn over the loop is not code compliant as there are now essentially two conductors under the clamp

grounds come off a busbar so you will always have separate grounds.

While I don’t get involved with grounding rods, this reminds me of an electrical outlet where I once noticed a grounding wire tied in with a plastic zip tie. At least, they used a metal strap here. LOL

What about using 2 clamps on a single ground rod?

I have two on one of my 4 rods (I have solar arrays, detached garage, sub panel in garage, lot going on). The one with two has the solar array on the house copper run going through a ground bar on the side of the house and continuing to the ground rod. Ground rod has the main ground from the main panel in the basement too. Will I change this / fix it because of 'code'? No, because it's better and not able to lose this ground connection even more so with how it's run. Keep in mind, both grounds going to the rod also go to that bus bar with 1-2 other connections there as well.

Hi can u pls send me the link to order a necklace hand book thanks

yeah in GA we call'em acorn clamps as well. I would like to know the scientific study behind "number of conductors" rated for them clamps, cause you would think the more copper touching each other the better in a grounding system. Then again in Fort Benning they required us to put in a grounding grid and cad weld each rod that went to the roof with multiple lightning rods. maybe they know something I don't, but I'd like to know.

@SparkyChannel

Hi! The companies that make the connectors, such as the acorn clamp, hire engineers to run tests. Then they publish their findings, then the manufacturers make their manufacturers specs.

Both, they're cut. Also, if the acorn is listed for 2 conductors, then it's allowed

Is it useful and allowed to coat the bare wire and clamp with heavy duty corrosion inhibitor since it is exposed to the elements?

I would say that the concern would be that it's performance would be compromised over time.

Not an electrician so excuse what isn't obvious at least to me. How is the one on the left considered 1 conductor or is that a different type clamp?

@SparkyChannel

It's one wire because it isn't cut. As we say, it's unspliced. The one on the right is spliced, so it has to be counted as 2 wires.

@TomCee53

10 ай бұрын

Probably less of an issue with stranded, but my guess is with solid wires there would be a tendency for one to be looser than the other.

Wire on the left keeps strands tightly bundled for maximum contact and ground fault current transfer. Wires on the right have strands that are spread out and loose which decreases total contact area. Without even knowing written code specifics, this should be obvious.

@SparkyChannel

10 ай бұрын

Excellent!

@ardgeighw5174

10 ай бұрын

The strands being spread out increases the surface area of the contact points, meaning that it should transfer the current better, at least from a purely mathematical viewpoint

Grounds are suppose to prevent electrical fires but I have seen maaaany times when a properly grounded 120 VAC receptacle burns up and catches on fire.
