Methods for Grounding Electrical Panels
Electrical Question: I am doing some renovations in my basement and need to remove a copper water line. I ‘m replacing it with PEX (plastic) pipe.
- 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.

The Safest Way to Test Electrical Devices and Identify Electric Wires!The Non-Contact Electrical Tester
This is a testing tool that I have had in my personal electrical tool pouch for years, and is the first test tool I grab to help identify electrical wiring. It is a Non-contact tester that I use to easily Detect Voltage in Cables, Cords, Circuit Breakers, Lighting Fixtures, Switches, Outlets and Wires. Simply insert the end of the tester into an outlet, lamp socket, or hold the end of the tester against the wire you wish to test. Very handy and easy to use.
The Quickest Way to Check for Faulty Electrical Wiring!The Plug-In Outlet Tester
This is the first tool I grab to troubleshoot a problem with outlet circuit wiring. This popular tester is also used by most inspectors to test for power and check the polarity of circuit wiring.
It detects probable improper wiring conditions in standard 110-125 VAC outlets Provides 6 probable wiring conditions that are quick and easy to read for ultimate efficiency Lights indicate if wiring is correct and indicator light chart is included Tests standard 3-wire outlets UL Listed Light indicates if wiring is incorrect Very handy and easy to use.
Strip Off Wire Insulation without Nicking and Damaging the Electric Wire!The Wire Stripper and Wire Cutter
My absolute favorite wire stripping tool that I have had in my personal electrical tool pouch for years, and this is the tool I use to safely strip electrical wires.
This handy tool has multiple uses:
The wire gauges are shown on the side of the tool so you know which slot to use for stripping insulation.
The end of the tool can be used to grip and bend wire which is handy for attaching wire onto the screw terminals of switches and outlets..
The wire stripper will work on both solid and stranded wire. This tool is Very Handy and Easy to Use.
