True False 2 In a medium voltage metal-clad switchgear assembly, all main bus and connections are insulated. True False 3 When selling Medium Voltage Switchgear in NEMA markets, "Metal-Clad" structures are always used. True False 4 Vertical structures of medium voltage switchgear are usually ____ inches wide. 26 36 42 All of the above 5 Safety interlocks are not required by governing standards and are supplied as an option by some manufacturers. True False 6 The secondary contact plugs can be manually engaged when the circuit breaker is in the TEST position. True False 7 The automatic shutter system prevents contact with live primary current carrying parts by closing when the breaker is levered out of the "CONNECTED" position. True False 8 Design and proof testing show compliance with ANSI standards and includes: Short circuit test Thermal tests Dielectric tests Continuous current test All of the above 9 This design component allows breakers and other devices to be withdrawn form their compartments for inspection and maintenance.

True False 11 Access to the line compartment is made through rear panels or doors. True False 12 ________ devices check and or regulate the flow of power in medium voltage switchgear. Control Switching/Interrupting Metering Protective 13 Primary and secondary electrical connections are made and live when the breaker is in the "TEST" position. True False 14 Medium voltage switchgear assemblies generally fall into the voltage categories of 5 and 15kV, 27kV, and 38kV. True False 15 The space between the front of the circuit breaker and the front doors of the assembly is occupied by the ________.

True False 17 The circuit breaker makes its primary bus connection using ________. Power Stabs Finger Clusters Clamps Jaws 18 When circuit breaker and/or auxiliary equipment is stacked in a medium voltage switchgear structure, temperature requirements must be considered. True False 19 The term "Metal-Clad" means that the structures (and compartments within each structure) are physically separated from each other by grounded metal barriers. True False 20 A weatherproof enclosure that allows switchgear, motor starters, and MCCs to be located in one area is called ________.
