1/2" ground rods

[jeff48356]

Since Code requires two 5/8" copper ground rods for each new service, why does the Home Depot even carry 1/2" ground rods? You'd be surprised at all non-Code compliant items that Home Depot sells. What are 1/2" rods used for if not for service grounding electrodes?

Are they listed and stamped? Reread 250.52(5)(b). Copper rods are never required.

Telco and cable grounding? Not that that's the proper way to do it, but still...

Where does it say 5/8” for rods?

 

[electrofelon]

"......Shall be 5/8 in diameter, unless listed." Is the wording

Auxiliary and communication rods are not required to meet code min standard as long as they are properly tied to GES for the building. See 800.100 and 250.54.

See reference above.

I guess I’ve never seen an unlisted rod. Even the 5/8.

Never saw a telco 4’ or 6’ rod?

Never saw a telco 4’ or 6’ rod?

Never pulled one up to measure it.

i did see a bundle of short ones designated for a company that sells portable lighting systems, but nothing else that I remember.

When I did resi up grades I was taught to always assume that all grounding, electrical and telco, was inadequate unless verified.

I never verified crap, just supplemented with code legal options and left the other stuff as auxiliary and not subject to code mins.

. . . why does the Home Depot even carry 1/2" ground rods?

Actually, they're copper-clad. If you look closely, you can see that the copper is spirally wrapped.

And I use them all the time.

Even plain zinc coated (galvanized?) 1/2” rods are legal if listed.

I bought some LFMC at the supply house today, it was non-UL listed. They started selling a bunch of generic off-brand stuff lately. :roll:

Okay, you keep posting rolling eyes smileys at me,. Why?

What post of mine on the rods do you find incorrect?

Yup, if it's a 5/8" rod no listing required, 1/2" required. It can even be a piece of 3/4" RMC.

 

[Dennis Alwon]

The one at Lowes are 1/2" and are listed

Here is what the code states

Rod-type grounding electrodes of stainless steel and
copper or zinc coated steel shall be at least 15.87 mm (5∕8 in.) in
diameter, unless listed.

 

[chris1971]

We use listed 1/2”ground rods all the time. What’s the issue?







None.











Thought so.
