Incorrect Outlet Ground Wire Could be a Shock Hazard
By Dave Rongey - Summary:|
The Danger of Incorrectly Connecting a Ground Wire to a Outlet: Why a Ground Wire Should Not be Used as a Neutral Wire on a Receptacle Outlet.
Ground Wire Shock Hazard
- 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?
Background: John, a Homeowner from Nampa, Idaho.
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.
