Final answer:
Transformer secondary conductors are not protected by the primary overcurrent device. They have their own overcurrent protection devices on the secondary side.
Step-by-step explanation:
Transformer secondary conductors are not considered to be protected by the primary overcurrent device. The primary overcurrent device is designed to protect the primary side of the transformer from excessive current. It is typically located on the primary side and is responsible for interrupting the current flow if it exceeds a certain predefined value. The secondary conductors, on the other hand, are protected by their own overcurrent protection devices, such as circuit breakers or fuses, which are specifically designed for the secondary side. These devices ensure that the secondary conductors are not exposed to excessive current that could lead to overheating or other safety hazards.
