Final answer:
An elbow bend is a 90° bend in conduit made perpendicular to the original length of conduit. It is commonly used in electrical installations to change the direction of the conduit around corners and obstacles. Elbow bends are available in different angles to suit different installation requirements.
Step-by-step explanation:
An elbow bend is a 90° bend in conduit made perpendicular to the original length of conduit. It is commonly used in electrical installations to change the direction of the conduit around corners and obstacles. Elbow bends are available in different angles, such as 90°, 45°, and 30°, to suit different installation requirements.
For example, in Figure 5.24, a telephone pole with a 90° bend in the power line is shown. This bend allows the power line to change direction while maintaining the necessary clearance from other objects. Similarly, in Figure 5.22, an illustration of a telephone pole at a 90° bend in a power line is provided, demonstrating how a guy wire is attached to the top of the pole at an angle relative to the vertical.
Overall, an elbow bend is a crucial component in conduit installations and plays a significant role in the direction and organization of electrical wiring.
