Wiring Diagnosis & Short Circuit Repairs in Greater Taunton-Raynham, MA
Diagnosing wiring issues begins with a visual inspection of outlets, switches, and breaker panels to check for obvious damage, burn marks, or loose connections.
At Cotti-Johnson HVAC, Inc., our electricians use tools like multimeters and circuit testers to identify voltage drops, continuity problems, or abnormal current flow. To locate a short circuit, they may isolate affected circuits by turning breakers off and on, testing each wire section.
Once the faulty wire or connection is found, it’s repaired or replaced—often by removing damaged insulation, tightening connections, or running new wire. Finally, the system is retested to ensure safety and functionality before power is restored.
Outlet Not Working? Voltage Drop Testing Solutions
When an outlet stops working, one possible cause might be an excessive voltage drop, which means electricity isn’t flowing efficiently due to resistance in the wiring. This can be caused by loose connections, corroded wires, or damaged conductors.
Our electricians can use a multimeter to test the voltage at the outlet. A properly working outlet should read around 120 volts (in the US). If the voltage is significantly lower, they can perform a voltage drop test by applying a load (such as a test light or a plug-in device) and measuring the voltage again. A noticeable drop indicates resistance somewhere in the circuit.
A whole house safety inspection ensures your electrical system is working efficiently and safely. Call us for details.
Preventative Electrical Troubleshooting Tips
While a professional electrical system inspection is something you should get on a regular basis, there are things you can do yourself to ensure your electrical system is safe and to find problems before they escalate. Here’s what you can do.
- Inspect Outlets and Switches: Check regularly for signs of wear, discoloration, or warmth, which could indicate a problem.
- Tighten Connections: Periodically tighten wire connections in outlets, switches, and panels to prevent arcing and voltage drops.
- Test GFCIs and AFCIs: Press the “Test” and “Reset” buttons monthly to ensure ground fault and arc fault breakers work properly.
- Monitor Circuit Load: Avoid overloading circuits by balancing appliance use and upgrading circuits if needed.
- Use Surge Protection: Install whole-house or plug-in surge protectors to shield electronics from power spikes.
- Check for Tripped Breakers: If power is lost, check the breaker panel and reset any tripped breakers, but also investigate the reason they tripped.
