Where must a bushing be located when flexible cord enters a portable lamp?

The lamp shade
The base or stem of a portable lamp
The power entry point of a wall
The wiring compartment of a fixture

The correct answer is: The base or stem of a portable lamp

The bushing plays a crucial role in ensuring the safe entry of flexible cords into portable lamps. When the flexible cord enters the lamp, it is essential for the bushing to be located at the base or stem of the portable lamp. This location serves multiple purposes: it protects the cord from abrasion or damage at the entry point, offers strain relief, and helps prevent electrical shorts that could occur if the cord were to rub against sharp edges or other materials. Positioning the bushing at the base or stem also maintains the structural integrity of the lamp, allowing it to function effectively without risking the safety of the user. The other locations mentioned, such as the lamp shade or wiring compartment, do not provide the same level of protection and functionality for the flexible cord, which is why they are not suitable alternatives.
