In which order do you connect a safety ground when installing it on isolated equipment?

  2. Attach both ends at exactly the same time
  3. Attach it to the equipment, then add a ground rod
  4. Attach it to the ground point first, then the equipment
Show answer

Correct answer: Attach it to the ground point first, then the equipment

The ground connection is made first so the equipment is never connected to a ground lead that is not grounded.
