4 1-26.   If a 28 volt 6 ampere fuse blows, the proper procedure is to replace it with which of the following devices? 1.  A larger fuse until the cause of the overload has been determined 2.  A fuse of the same voltage and current rating 3.  A fuse rated 20 percent lower than the blown fuse 4.  A copper strap until the cause of the overload is determined 1-27.   Before electrical equipment is overhauled or repaired, what general safety precaution, if any, should be followed? 1.  The fuse for the associated circuits should be replaced with circuit breakers 2.  The main supply switches should temporarily be shorted out 3.  The power switches should be secured open and tagged out of service 4.  None 1-28.   After work on equipment is complete, who should remove any attached tags? 1.  The job inspector 2.  The repair crew leader 3.  Any member of the repair crew 4.  The person who signed and attached the tag 1-29.   What is the purpose of the grounding cable attached to the frame of a generator aboard ship? 1.  Create a potential difference between the frame and the ship 2.  Conduct power to the generator under emergency conditions 3.  Ensure equipment is at same ground potential as the ship 4.  Break the circuit between the frame and the power supply under emergency conditions 1-30.   Which of the following steps should you take to help ensure that metal-case test equipments are safe to use? 1.  Energize the instrument to test the ground 2.  Ensure the equipment is grounded 3.  Insulate the metal case from ground 4.  Connect all metal cases to a common ungrounded lead 1-31.   Which of the following precautions should you observe when using measuring instruments? 1.  Avoid strong magnetic fields 2.  Avoid excessive current 3.  Avoid mechanical shock 4.  Each of the above 1-32.   The meter movement in a voltmeter can be easily damaged by excessive current if you do not follow certain procedures. When setting up the meter to read voltage, the RANGE SWITCH should first be set to (a) what relative range and then changed to (b) what relative range? 1.  (a) Highest (b) Closest to the voltage to be read 2.  (a) Highest (b) Lower than the voltage to be read 3.  (a) Lowest (b) Lower than the voltage to be read 4.  (a) Lowest (b) Closest to the voltage to be read
