Bootleg ground

Bootleg ground or false ground refers to an improper electrical wiring practice where the ground and neutral wires are intentionally connected together at an outlet or device. This is often done in an attempt to provide a grounding path without installing proper grounding infrastructure. Bootleg grounds are considered dangerous and are against electrical codes in many jurisdictions because they can create a potential shock hazard and interfere with the proper operation of electrical devices and safety mechanisms.

Overview

In a properly wired electrical system, there are typically three types of wires: hot, neutral, and ground. The hot wire carries current to the device, the neutral wire carries current back to the power source, and the ground wire provides a safe path for electrical current in case of a short circuit or other malfunction. A bootleg ground occurs when the ground terminal is connected to the neutral terminal, either at the outlet or within the device being powered, in an attempt to mimic a grounded connection.

Risks and Hazards

The primary risk associated with a bootleg ground is electrical shock. Because the neutral wire carries current under normal operation, connecting it to the ground terminal can energize the grounding system. This means that metal parts of appliances and electrical boxes that should be safe to touch could become electrified, posing a serious shock hazard to users.

Additionally, bootleg grounds can compromise the integrity of an electrical system's grounding, which is designed to protect against electrical fires and damage to sensitive electronics by providing a low-resistance path to earth for fault currents. In the event of a fault, a bootleg ground may not provide an effective path for the current, increasing the risk of fire or damage to electrical components.

Detection and Correction

Detecting a bootleg ground can be challenging without the proper tools. Electricians often use specialized testers to identify improper wiring, including bootleg grounds. Once identified, correction involves removing the improper connection between the ground and neutral wires and ensuring that a proper and safe grounding method is established according to local electrical codes.

Legal and Safety Considerations

In many jurisdictions, creating a bootleg ground is illegal and violates electrical codes. Electrical work should always be performed by qualified professionals who are familiar with the local codes and standards. Homeowners and building managers should be aware of the dangers of bootleg grounds and take steps to ensure their properties are properly wired and safe.

Conclusion

Bootleg grounds are a dangerous and illegal practice that can compromise the safety of an electrical system. Proper grounding is essential for the safe operation of electrical devices and the protection of people and property from electrical hazards. It is important to address any suspected wiring issues promptly by consulting with a professional electrician.
