Proper Installation of Ground Rod
The ground rod should not be driven into dry ground.
Follow these instructions for proper installation:
1. Dig a hole large enough to hold 1 to 2 gallons of water.
2. Fill hole with water.
3. Insert rod through water and jab it into the ground.
4. Continue jabbing the rod up and down. The water will work its way down the hole, making it possible
to work the rod completely into the ground. This method of installing the rod gives a good conductive
bond with the surrounding soil.
5. Connect the bare copper ground wire to the rod with the proper ground rod clamp. (See Figure 4B
on Page 37.)
6. Connect the bare copper ground wire to the fan control boxes with a grounding lug.
7. Ground wire must not have any breaks or splices.
