Plug-In Tester Shows an Outlet Problem
- My “Bull Head Tester” or circuit outlet analyzer is indicating that a defective receptacle I was trouble shooting needs the ground and neutral wires reversed.
- All the neutral wires are on the bottom bus bar and the ground wires are all on the right bus bar.
This electrical repair question came from: Roy, a Inspector from Durham, North Carolina.
Thanks for your electrical repair question Roy.
How to Repair Outlet Electrical Wiring
Application: Troubleshooting and Repairing Outlet Problems.
Skill Level: Intermediate to Advanced – Best performed by a Licensed Electrician.
Tools Required: Basic Electricians Pouch Hand Tools, Voltage Tester or Volt Ohm Meter or plug-in circuit analyzer.
Estimated Time: Depends on the age of the home and the condition of the electrical wiring and access to the circuit wiring to be evaluated.
Precaution: Identify the outlet circuit, turn it OFF and then Tag it with a Note before performing any wiring inspections or electrical repairs.
Re-Wiring a Receptacle Outlet
- Not all ground and neutral terminal strips are in the same locations.
- The layout of the electrical panel may be unique to the age and brand of the panel.
Plug-In Tester Readings
- When a plug-in receptacle outlet tester indicates that an outlet is not wired correctly the problem is usually the wiring at the outlet and not at the electrical panel.
- In fact the neutral and the ground wire should never be reversed in a sub-panel where the ground and neutrals are isolated and on their own terminal strip.

How to use a Plug in Tester and Circuit Analyzers for Testing Outlets
- The circuit should positively identified and shut off. The wiring at the outlet should be inspected and corrected as needed. If the outlet wiring is correct and the plug-in tester shows a fault then there may be a problem somewhere else within the circuit wiring, such as another outlet box, switch box or a junction box.
- Polarity testing of the affected circuit may be required and is best performed by a qualified licensed electrician who will be able to identify the problem and make the necessary repairs.
