Reversing the live and neutral connections in an electrical circuit can have serious consequences and should never be done. In a standard electrical wiring configuration, the live wire (also known as the hot wire) carries the electrical current from the power source to the appliance or device, while the neutral wire provides a return path for the current to complete the circuit. This configuration is designed to ensure safety and proper functioning of electrical devices.

If you reverse the live and neutral connections, several potential issues and dangers can arise:

Electrical Shock: Reversing the connections can lead to the appliance or device becoming live even when it's switched off. This can result in electric shocks if someone comes into contact with it.

Appliance Damage: Many electrical appliances are designed to work with the live and neutral wires connected in a specific way. Reversing the connections can damage the appliance or cause it to malfunction.

Fire Hazard: In some cases, reversing the connections can increase the risk of overheating and potential fire hazards. It can also disrupt the operation of safety mechanisms built into electrical devices.

Violation of Electrical Codes: Electrical codes and regulations typically require proper wiring connections to ensure safety. Reversing live and neutral wires would be a violation of these codes.

Inaccurate Polarity: Reversing the connections can lead to incorrect polarity in electrical circuits, which can affect the performance of sensitive electronic devices and cause issues with lighting fixtures.

To sum it up, reversing the live and neutral connections is dangerous and can lead to electrical hazards, appliance damage, and safety violations. If you suspect a wiring issue or need electrical work done, it's essential to hire a qualified electrician to ensure that the wiring is correctly installed and compliant with safety standards.
