grounded
A tee module elbow is identified as a 600 Amp elbow, the 600 Amp indicates that this is the elbows __?__.
continuous current rating
The purpose of an elbow’s operating eye is to provide a point where a(n) __?__ can be attached for operations.
live line tool (shotgun stick)
The term loadbreak, when referring to a 200 Amp elbow means that the elbow is designed to make and break an energized circuit.
true
An industrial plant uses 15 kV, 200 Amp loadbreak elbows for their motor connections. However, they do not want to disconnect them under load. If the motor circuits are de-energized, the elbows can be operated as __?__ elbows.
deadbreak
A separable connector is another name for a(n) __?__.
elbow
IEEE Standard __?__, (“Separable Insulated Connector Systems for Power Distribution Systems above 600 V”) is the industry standard that sets specifications for elbow interchangeability among manufacturers.

ground (drain) wire
A transformer can be ordered as a dead-front with 200 Amp bushing wells. A bushing well is an apparatus bushing component that forms a cavity to __?__.
accept and accessory
A bushing insert is a 200 Amp loadbreak accessory that is often included when ordering a 200 Amp loadbreak elbow, a bushing insert is a screw-in bushing that is required to connect the elbows to.
true
A 200 Amp loadbreak elbow contains a probe that serves as a contact for the connector and has a polymer tip. The purpose of the polymer tip is to __?__ when operating the elbow under energized conditions.
suppress the arc
An elbow’s operating interface is the tapered interface surfaces that are mated or separated during make and break operations.
true
The 200 Amp loadbreak and the 200 Amp deadbreak elbows use different methods for securing their bushing attachments. The loadbreak uses a locking ring. The method used to secure the deadbreak elbow is the __?__.
bail assembly
The 200 Amp insulated plug used to park an energized or de-energized elbow is called a(n) __?__.
stand-off plug
