Insulated lineman's pliers are designed with a protective layer, usually made of rubber or plastic, that covers the handles. This insulation is specifically engineered to protect users from electrical shocks by preventing the conduction of electricity through the handles. These pliers are typically rated for a certain voltage level, often up to 1000 volts, and are used by electricians and other professionals who work with live electrical circuits. The insulation also provides a better grip, reducing the risk of slipping during use. Non-insulated lineman's pliers, on the other hand, lack this protective layer. They are made entirely of metal, except for the handles, which may have a basic plastic or rubber coating for comfort and grip, but not for electrical protection. These pliers are suitable for general-purpose tasks such as cutting, twisting, and gripping wires, but they should not be used on live electrical circuits due to the risk of electrical shock. The primary difference lies in the safety features: insulated pliers offer protection against electrical hazards, while non-insulated pliers do not. This makes insulated pliers essential for electrical work, whereas non-insulated pliers are more appropriate for mechanical tasks where electrical safety is not a concern.
