Exclamation grounding rod

How do you determine the size of grounding rod for service on a house. Is there some kind of chart to use or anything like that.?

Thanks any help would be great.

The relevant Code Article is 250.52, Grounding Electrodes, (A), (5), which requires a rod NLT 8 ft. in lenth and NLT 5/8" in diameter.

Good Luck & Enjoy the Experience!!!!!!!!!!!!

According to what I read, Code requires a minimum of a 5/8-in diameter rod. Other sizes are 3/4" and 1". I believe they're supposed to be 8' long and must now be driven below ground level. In the past, I've seen rods sticking up out of the ground, with the EGC attached with a metal clamp. I always thought that was odd, and is now, I believe, against code since "leaving one end out of the ground could be a trip and lawnmower hazard". Rex Cauldwell - Wiring A House I always thought of the neighborhood jerk vandalizers cutting the ground wire for you. So, I always thought it odd to leave it sticking out.

I'm not a pro, so stand by for more info. Just wanted to see if I knew or have learned anything yet
