The Ground System of Home Electrical Wiring
Electrical Question #1: I have been upgrading some of the fixtures and dimmer switches in my house.
- It is a recent construction circa 2006. Often times I see that many switches and fixtures throughout my house are not grounded.
- Either the ground wire is not connected to anything or the ground wire has been removed altogether. Is this OK? What problems can arise?
- It has never presented a problem, and everything functions fine.
- Finally, when installing these fixtures and switches where would I ground them? To the junction box?
Thanks for your time and consideration.
Background: Glenn, a Homeowner from Chicago.
Electrical Question #2:
- I am buying a home built in 1958. The inspection came back acceptable but outdated 2 pole wiring with no ground. How do people use common 3 prong devices with a 2 prong wiring system? I have heard about adapters and 2 prong power surges but not sure how reliable these are. How should I upgrade the outlet circuit and add a ground wire?
This electrical wiring question came from in Clarksville, Georgia

Thank you for your electrical questions.
The Essential Grounding System of a Home
Application: Home Electrical Ground System.
Skill Level: Intermediate to Advanced. This electrical project is best performed by a Licensed Electrician.
Tools Required: Basic Electrical Hand Tools and a Voltage Tester
Estimated Time: Depends on personal experience and the number of switches and outlets being replaced.
Correcting an Ungrounded Condition of Home a Electrical System
- When installing home electrical wiring all wiring must include a ground wire, except low voltage wiring where a ground is optional depending on the low voltage system.
- All electrical ground wires must be bonded or spliced together.
- If the junction box is metallic or provides a ground termination then the ground is to be attached there as well.
- If there is a device that is installed in the electrical junction box such as a switch or outlet and the device has a ground screw terminal then a ground wire must be attached to it as well.
With this information I think you’ll agree that the ground wires of your home electrical wiring system are not bonded which in this case cannot provide the protection that a ground system provides. I would have this taken care of.
NOTE: A electrical contractor would know how to take care of this for you and inspect the integrity of the ground system at the main electrical panel which is vitally important above.

The Safest Way to Test Electrical Devices and Identify Electric Wires!The Non-Contact Electrical TesterThis 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 TesterThis 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 CutterMy 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.
