electrical landscape question
Its spring afterall!
Got a new service. Electricians drove a ground rod outside. They went just a little lower than grade. I am afraid when I lay new mulch it will cover the acorn clamp and some of the wire. If I lay topsoil, it will also cover the connection.
Is that ok? What can I do in this case?
And how does the bare copper not deteriorate so close, or in contact, with the ground?

The connections need to be flush or below grade. As long as they are listed for direct burial you should have no issues.

I also noticed where they made the connection, with the screw compression, the stranded wire kind of flattened out, the strands aren't tightly twisted under that acorn clamp... does that sound like an issue?
As far as burying it, I will do so, I trust you guys but that seems weird that its allowed to deteriorate in the ground like that....

I just ran a GEC for a garage subpanel. Using 'Table 250.66' said I can use #8 ... what am I missing?
Good luck with the landscaping mummy.

PC BOSS That sounds too small, although it is never required to be larger than #6.

#6 you can just run along the building surface as long as it is free from physical damage.

No, I wasn't missing that. I ran it in pvc. The original poster didn't say it was ran in conduit or not but I would assume if an electrician did it, then the #8 is also in conduit.
I think the OP was concerned about the exposed portion at the rod/acorn clamp. Which now that I think of it in regards to my similar setup, its a valid concern about covering up the smaller wire with dirt.
