What ground rod means
A ground rod is a metal rod driven into the earth and connected to the electrical service, giving the system a connection to earth.
Also called grounding electrode.
Where it matters on a electrical job
Service upgrades usually include checking or adding ground rods and the bonding to water and gas pipes. Rocky ground can make driving rods slow, so look at the site before you price it.
What the model code says
- Rod electrodes must be at least 8 feet long. (IRC 2021, Chapter 36)
- They are driven so at least 8 feet is in contact with soil, or laid at an angle or in a trench at least 30 inches deep where rock is hit. (IRC 2021, Chapter 36)
Check which code edition your building department enforces for ground rod before you quote.
