What safety equipment should be used when changing a fuse in a live circuit?

When changing a fuse in a live circuit, insulated fuse pullers are the most appropriate safety equipment to use. These tools are specifically designed to handle electrical components while providing an added layer of protection against electric shock. The insulation on the pullers minimizes the risk of electrical contact and helps ensure the user's safety.

Using insulated tools is critical in live electrical work because they prevent accidental contact with conductive surfaces, thus reducing the likelihood of electrocution or injury. Insulated fuse pullers have been tested to withstand the high voltages found in live circuits, giving the user confidence that they are safer than standard tools without insulation.

While rubber gloves can provide some protection, they are less effective when manipulating fuses directly and may not meet the necessary standards for high-voltage environments. Similarly, pliers and standard fuse pullers lack sufficient insulation to safely handle live circuits, which exposes the user to greater risks in situations where electrical contact is possible.
