Experiencing a shock when touching your new stove while another electrical appliance is also running is likely due to a phenomenon called "ground potential difference" or "ground loop." This occurs when there is a voltage difference between the ground points of different electrical devices.

Here's how it happens:

  1. Grounding System: Electrical devices, including stoves and other appliances, are usually connected to a grounding system. The grounding system is designed to provide a safe pathway for electrical currents to flow to the ground in case of a fault or electrical surge, protecting users from electric shocks and preventing damage to the appliances.

  2. Ground Potential Difference: In some cases, different electrical devices may have slight voltage differences in their grounding systems due to the way they are wired or due to issues with electrical distribution in the building. This can create a "ground potential difference" between the appliances.

  3. Current Flow: When you touch the metal surface of your stove and another electrical appliance simultaneously, the current from one device may flow through your body to reach the other device, causing an electric shock. Your body completes the circuit between the two devices, and the shock occurs due to the small voltage difference between them.

  4. Insulation: Additionally, if you are standing on a floor that is a good conductor (e.g., wet floor or conductive flooring materials), it can enhance the shock sensation as it provides a better pathway for the current to flow through your body.

To prevent such shocks, consider the following measures:

  1. Ensure Proper Grounding: Make sure all electrical devices, including the stove and other appliances, are correctly grounded according to local electrical codes.

  2. Isolate Appliances: Try to avoid touching multiple electrical appliances simultaneously, especially when they are connected to different power sources or outlets.

  3. Address Electrical Issues: If you frequently experience shocks or suspect a ground potential difference issue, it's essential to have a qualified electrician inspect and address any electrical problems in your home's wiring or grounding system.

  4. Wear Footwear: Wearing non-conductive footwear, such as rubber-soled shoes, can help reduce the chance of electric shocks if you accidentally touch a live electrical component.

Always prioritize safety and consult with a professional electrician if you have concerns about electrical shocks or grounding issues in your home.
