摘要： A PAIR OF INTERLOCKING BUS BARS ARE PROVIDED FOR A WATT-HOUR METER TO ELIMINATE RISK OF SHORT CIRCUITING METER COMPONENTS WHEN ONE OF THE BUS BARS, WHICH HAS AN INTEGRAL TERMINAL ON IT, IS CONNECTED TO THE METER TO CONVERT IT FROM A FOUR TERMINAL METER TO A FIVE TERMINAL METER. THE INTERLOCKING MEANS OF THE RESPECTIVE BUS BARS PREVENT THE FIFTH TERMINAL FROM BEING PLACED IN OPERATING POSITION WHILE THE FIRST BUS BAR IS SERVING AS A TEST LINK CONNECTED BETWEEN TWO TERMINALS ON THE METER BASE PLATE.
