What gauge ground wire should you use for grounding rod for 200 amp service?

Answer for USA, Canada and countries running a 60 Hz supply service.

Standard ground rod is 5/8th inch diameter and 8 feet long and the conductor connected to it is bare #6 AWG copper. Where I live we are required 2 rods, and NEC requires them to be placed a MINIMUM of 6 feet apart. These rods are treated in the NEC as SUPPLEMENTAL to a water line ground.

As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.

Before you do any work yourself,

on electrical circuits, equipment or appliances,

always use a test meter to ensure the circuit is, in fact, de-energized.
