What is the correct procedure for installing protective grounds?

The correct procedure for installing protective grounds emphasizes that the ground end should be attached first. This is crucial for ensuring safety when working on or near energized lines. By connecting the ground to the structure or equipment before making any other connections, you create a safe path for any fault currents that may occur. This means that if there is a fault or accidental contact with the line while you are working, the ground will provide a safe route for electrical energy to dissipate, significantly reducing the risk of electrical shock or injury to the worker.

In practice, this procedure establishes safety protocols that protect linemen from accidental electrocution or injury due to unexpected energization of the line. By prioritizing the attachment of the ground end, you effectively establish a buffer or safety zone, creating a more secure working environment.

While testing the line before grounding is important for ensuring that the line is de-energized, that does not take precedence over safely grounding the equipment first. Similarly, connecting the line while it is energized or using wire without prior checks would be considered dangerous practices that are not aligned with safety protocols. Therefore, attaching the ground end first is not only a procedure but a fundamental aspect of safe electrical work.
