when using two ground rods , is it require to run single ground wire for both ground rods or separate grounds for each

Either-- I usually run one wire and loop it long to the other rod.

You may have trouble terminating 2 wires if they originate in the meter base.

You can also run one to the first rod then use a jumper from the first to the second rod. I prefer the first method I discribed.

if you do use a jumper, gotta use irreversible crimp on the connection

Sidd lets assume we have a service with just two ground rods for the electrodes.

The conductor from the panel to the first ground rod is the GEC and can only be spliced with irreversible means.

However the conductor from the first rod to the second rod is not a GEC it is a bonding jumper and you can splice it and terminate just like any other conductor.

Check out this NEC handbook image.

That picture shows what you do when the inspector points out that you need a second ground rod.:grin:

True, but it does show Bob's point that the GEC ends at the first rod. The connection to the second rod is a bonding jumper and does not require an irreversible connection as previously mentioned.

thank you for the insight, I never considered the 2nd g-rod as a jumper, but I see how the NEC looks at it now.
