The E-Z Test 99800 series of meter test jacks are designed to increase safety and to simplify testing of socket-type watthour meters. They feature dead-front construction, which means that no accessible part of the test jack is 'live' until the tester chooses, and a unique, simplified connection system. Four types are available for safe, convenient and efficient field testing of virtually all commonly used socket-type meters.
Molded from a tough, glass-impregnated polycarbonate, E-Z Test 99800 meter test jacks will withstand the rigors of daily field use. Time proven, lever-actuate cams are used to firmly connect the meter blades to the test jack. A husky bypass bus is incorporated to handle customer loads, even at extended range meter installations that use the new 320-ampere, self-contained meters.
All test jacks incorporate fuses for protection in the potential circuits. Each type of test jack is available with fuses -Y rated for 250 volts maximum, or for applications such as testing 277/480 meters, with fuses rated 600 volts maximum
