FAILURE TO DEVELOP THESEPROCEDURES COULD LEAD TO IMPROPER USEOR OTHER MORE SERIOUS CON-SEQUENCES.1-0 INTRODUCTIONType Vac Clad-W switchgear assemblies are designedwith all the bus work completely insulated for safety.Since the current carrying parts are not readilyaccessible, type VCP-W Manual Ground and TestDevice is designed for insertion into the breakercompartment to gain access to the primary stationarycontacts. It provides a convenient means to:1. Ground a circuit for maintenance work;2. Apply potential for cable testing; and,3. Access both bus and line circuits for “phasing out”.tests.CAUTIONBECAUSE OF THE UNIQUE APPLICATION ANDVAST VARIETY OF SYSTEM/USERREQUIREMENTS, SPECIFIC SAFE OPERATINGPROCEDURES FOR THE USE OF THIS DEVICEMUST BE DEVELOPED BY THE USER.1-1 DESCRIPTIONThe device consists of a drawout element that can beinserted into a circuit breaker compartment in the samemanner as a type VCP-W circuit breaker. It includes sixterminals and ground bus connections. Each terminal isisolated from each other and the ground bus connectionby insulating barriers. The upper and lower terminals areaccessible upon opening the respective front hingeddoor. The ground connection is located in the lower frontsection of the device.Vac Clad-W switchgear is a two-high arrangement. Inthe lower compartment the top terminals normallyconnect to the main bus and the bottom terminalsnormally connect to the incoming line or feeders. In anupper compartment, the opposite normally holds true,i.e., the top terminals connect to the incoming line orfeeders and the bottom terminals connect to the mainbus. This must be verified for each application. Becauseof this two-high arrangement, the bus and the linepositions of the grounding and test device terminals willvary depending upon whether the device is used in anupper or lower compartment. Therefore, it is mostimportant that the bus or line terminals be correctlyidentified for each compartment before using thisdevice.
