The main idea is to minimize your exposure to arc flash and other hazards when inserting or removing a breaker from a panel. Using tools that extend your reach or operate remotely lets you stay farther away from live parts, which reduces the energy your body could be exposed to if an arc or fault occurs. Extended-length or remote-operated racking tools are specifically designed to let you perform the racking while keeping your hands and body outside the most dangerous zones.

A standard-length tool doesn’t provide as much distance, so your hands and arms are closer to energized parts. No tool needed would require you to place yourself inside the panel or very near energized components, greatly increasing risk. A magnetic racking device might seem helpful, but it doesn’t consistently guarantee sufficient distance or compatibility with all breakers and panels, so it’s not the best universal solution for reducing exposure.

So, extended-length or remote-operated racking tools offer the best protection by maximizing the distance from potential arc flash energy during racking.
