The Earthing ground rod is a practical solution for such older structures, as well as for regions around the world without an updated grounding (Earthed) system.
Step 1: (Optional) Using The Ground Rod When Outlets Aren't Grounded
1. First Push the Ground Rod directly into the earth (8" to 10") close to the foundation of the building.
2. Run the cord from the Ground Rod, under or around a window or door, near where you will be using your product.
3. Make sure to cover the cord to prevent tripping.
4. Plug the prong end of your cord into the receptical end of the Ground Rod cord. If you live in a dry area, such as a desert, soak the earth around the Ground Rod from time to time for maximum conductivity.
