What safety measure should be taken when working on live electrical circuits?

When working on live electrical circuits, implementing appropriate safety measures is crucial to protect oneself from electric shock or injury. Wearing rubber-soled shoes helps provide insulation between the person and the ground, which can significantly reduce the risk of electrical shock. Rubber is a poor conductor of electricity, so this footwear can offer an extra layer of protection.

Using insulated tools is equally important. Insulated tools are designed to withstand high voltage and prevent electrical currents from passing through the tool to the user. This feature helps ensure that even if the tool makes accidental contact with live electrical components, the insulation will protect the electrician from being shocked.

Both wearing rubber-soled shoes and using insulated tools together create a safer working environment, especially when dealing with live circuits. By following these measures, electricians can minimize the hazards associated with working on energized systems, allowing them to perform their tasks more securely and effectively. This is why the combination of both safety practices is the best choice in this scenario.
