7 1-47.   If a fluorescent light is to be attached to a branch circuit, which of the following splices should normally be used? 1.    Staggered splice 2.    Knotted tap joint 3.    Western Union splice 4.    Fixture joint 1-48.   When is a knotted tap joint normally used? 1.    When a branch circuit is joined to a continuous wire (main wire) 2.    When a Western Union splice would be too bulky 3.    When a lighting fixture is joined to a branch circuit 4.    When a wire nut is used to complete the joint 1-49.   Which of the following splices is NOT butted? 1.    Fixture joint 2.    Rattail joint 3.    Knotted tap joint 4.    Western Union splice 1-50.   Why is friction tape used over a splice? 1.    To provide a protective covering over the rubber tape 2.    To provide maximum insulation to the splice 3.    To prevent shock when latex rubber is used 4.    To reduce the amount of rubber tape required 1-51.   Why would you use a crimped terminal instead of a soldered terminal? 1.    Connections can be made more rapidly 2.    Less operator skill is required 3.    Connections are more uniform in construction 4.    Each of the above 1-52.   When noninsulated splices and terminal lugs are insulated, what types of insulation are most commonly used? 1.    Rubber tape and friction tape 2.    Spaghetti and heat-shrinkable tubing 3.    Spaghetti and friction tape 4.    Rubber tape and heat shrinkable tubing 1-53.   When heat-shrinkable tubing is used, what is the maximum temperature to which the wire should be subjected? 1.    180ºF 2.    220ºF 3.    300ºF 4.    340ºF 1-54.   When a large aluminum terminal lug or splice is installed, why is it NOT necessary to clean the aluminum wire? 1.    It is done automatically by the tubing 2.    The wire is cleaned by the abrasive compound in the lug or splice 3.    Oxide film does not form on aluminum 4.    The insulation used provides the necessary cleaning agent 1-55.   When aluminum terminals lugs or splices are installed, which of the following tools is generally recommended for use? 1.    Pliers 2.    Power crimping tool 3.    Hand crimping tool 4.    Vise grips
