<p>PROBLEM TO BE SOLVED: To provide a safety tool allowing a safe and efficient replacing work of integrating wattmeter by dissolving the danger of causing a short circuit accident or injury of human body, in the fastening or loosening work of a fastening and fixing small screw for every wire to an integrating wattmeter, by the contact of the tip of a driver tool with the small screw of the adjacent other wire by its lateral slippage. SOLUTION: This interpole insulating tool is formed of a frame of U-shape in front view formed of a horizontally long main plate 1 and side plates 2 and 2 provided continuously downward from both the ends thereof. The lateral length thereof is set to the length extending over a wire fixing part (a) in the integrating wattmeter M. The main plate 1 has a plurality of window holes 3 formed in conformation to individual wire fastening parts (b) in the integrating wattmeter M, and the side plates 2 and 2 have lateral positioning projections 4 and 4 protruded to the mutually opposed directions. Further, a plurality of partitioning walls 5 for partitioning individual wire insert holes h are integrally formed on one longitudinal side of the main plate 1.</p> |
