Electrical Panel Grounding Methods
Electrical Grounding Methods and Requirements – Listing of electrical codes for grounding with examples of electrical grounding codes for home electrical wiring.
Methods for Grounding Electrical Panels
- Home Electrical Ground Problem:
- My 100 amp electrical service panel ground is connected to the existing copper pipe.
- My plan is to relocate the ground. I am going to clamp the wire to a iron C channel foundation support.
- The foundation support has a 1 foot all-thread solid bar penetrating through the foundation and extending out into the yard 12 feet, 3.5′ underground.
- The iron C channel is in the same location, so the existing ground wire is long enough.
- Is this ground sufficient?
- And will I have to kill the power to the panel before moving the ground?

Thanks for your electrical wiring question Mark.
Grounding Methods for Home Electrical Panels
Skill Level: Advanced – Licensed Electrical Contractor, Not Recommended for Homeowners.
Tools Required: Electricians Pouch of Hand Tools.
Estimated Time: Depends on the extent of the project, the grounding method to be used and available access to the project area.
Precaution: If the only ground source for the electrical system will be removed or modified then the electrical service should be shut off until the new ground source can be reconnected.
Notice: Making changes to the Electrical Service Panel should be done with a permit and be inspected.
- Mark, check with your local building department about the C channel that you are referring to.
- The depth of the channel is greater than the required 30 inches and it is longer than the required 8 feet however I am not familiar with the type of material that the C channel is made of or its ability to provide the necessary conductivity and resist corrosion.
- An alternative is to consider driving a ground rod or two depending on your location and conditions.
- If you are removing the only ground source from the main electrical panel then the panel should be shut off until the ground source can be reconnected.
