True about the trench and such. There is also some provision for attaching to a buried plate. BUT since I have moved and haven't unpacked all the books yet I can't find my code book so I can not quote chapter and verse.

In my case, I asked the inspector the question about what to do if I couldn't drive the rod in because of hitting rock. He said that the rod didn't have to be driven streight down, it could be driven in at an angle or even layed in a trench as long as it was at least 30 inches deep. ----- Original Message ----- From: Tom Fowle To: blindhandyman@yahoogroups.com Sent: Sunday, September 16, 2007 04:49 Subject: Re: [BlindHandyMan] electrical safety when plumbing with plastic As Dale suggests, there are places where you can't drive an 8 foot rod deep enough, My colleague Bill Gerrey lives in a section of San Francisco where there is a layer of serpentine rock maybe 4 feet below the surface of the ground, and apparrently it's nearly impossible to get through. A friend tried to drive a ground rod through it for ham antenna safety purposes and when they hit the rock the sledge nearly bounced back in his face because the rod just wouldn't go down further. don't know what the code requires for electrical grounding in that case, probably a number of shorter rods. to drive a rod that's taller than you are without a ladder, you use a large chunk of pipe with a cap on one end. You stand the rod where you want it, put the capped pipe over the top and stand next it. You raise the capped pipe with one hand while holding the rod further down with the other, and let the pipe fall on top the rod. Starts slow, and takes a while in hard ground, but beats sledging from top of a ladder. Of course after you get down a ways, you have to switch to a sledge because the pipe hits the earth. tom Net-Tamer V 1.13 Beta - Registered [Non-text portions of this message have been removed] [Non-text portions of this message have been removed]
