A ground rod by itself does what for metal parts that are not bonded?

A rod alone does not make unbonded metal safe.

  1. It makes them completely safe to touch
  2. It trips the breaker faster
  3. It does not lower their touch voltage to a safe value ✔

Why: Driving a rod does not give fault current a path back to the source. Metal parts must be bonded together to keep touch voltage low.

Huh, didn't know that: The IEEE defines touch voltage between a bonded metal structure and a point on the earth 3 feet away.

The dad joke
Why did the lonely ground rod feel useless? Nobody would bond with it.
