Ground Wire Shock Hazard
Electrical Question #1: Is it safe to wire the ground wire to the neutral side of the outlet?
John, a Homeowner in Idaho asks:
- I have and outlet with a broken neutral somewhere in the ceiling.
- I wired the ground wire to the neutral side of the outlet and it works.
- I get 120 volts.
- What are the dangers of this?
Dave’s Reply:
Thanks for your electrical wiring question John.
The Danger of Incorrectly Connecting a Ground Wire to a Outlet
Application: Wiring a 120volt Receptacle Outlet.
Skill Level: Advanced – Best performed by a Licensed Electrical Contractor.
Tools Required: Basic Electricians Pouch Hand Tools, Voltage Tester or Volt Ohm Meter.
Estimated Time: Depends on the type and age of the electrical wiring and the access to the circuits and wiring to be evaluated.
Notice: Repairs to Home Electrical Wiring should be done according to local and national electrical codes and installing new or replacement electrical parts or equipment may require a permit and inspections.
Why a Ground Wire Should Not be Used as a Neutral Wire on a Receptacle Outlet
NOTE: A ground wire should never be connected to replace the neutral wire. Make Sure to Avoid Creating This Dangerous Electrical Shock Hazard in Your Home, as I explain below.
- The ground wire is intended to be a non-current carrying conductor for the purpose of providing a bonded path to ground to help prevent damage to electrical equipment and to work with ground fault devices to aid in preventing electrical shock in the event of an electrical short or current to ground condition.
- By incorrectly using the ground wire as a neutral wire you are placing voltage onto the entire ground system thereby energizing all the normally grounded components of any electrical device which is connected to the bonded ground system of the entire home.
- Therefore, when any electrical device is plugged into this outlet which you have incorrectly wired, and return path voltage is produced back into the ground conductor, you are then creating a lethal electrical shock hazard throughout the entire home ground system.
- Lethal electrical shock hazards will then be created in areas such as the bathroom bathtub or shower, any sink and anywhere that a person comes into contact with the energized ground system and a less resistant path to ground.
- This condition also has the potential to harm any electronic device or equipment that is connected anywhere in the home.
IMPORTANT: With the condition of this electrical question, it would be best to immediately disconnect the incorrect wiring hazard that has been created and correctly proceed with whatever method that is necessary to repair the fault with the neutral wire, please see the following resources for further assistance.
Electrical Question #2
Paula in Michigan asks:
I have a bare wire on an outlet that acts like a neutral. If I hook the bare wire to the neutral screw terminal and the black wire to the hot the outlet works.
Dave’s Reply
- Paula, From what you have described, connecting the bare ground wire to the neutral screw terminal of the electrical outlet is creating a dangerous condition in your electrical system that could cause an electrical shock hazard in your home.
- Even though this alteration appears to work, it is a dangerous modification.
- If an electrical outlet is not working properly when it has been wired normally and without modification then there is a problem within the electrical circuit wiring that will need to be identified and corrected by a qualified electrician.

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. 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. |
