Which step is NOT part of installing bus jumpers?

The process of installing bus jumpers involves specific safety protocols and steps to ensure a successful installation. One critical aspect of this process is removing all power before the installation begins. This step is vital because it minimizes the risk of electric shock or inadvertent activation of the system while personnel work on the jumpers.

Inspecting bus jumpers and receptacles for damage is a proactive safety measure that ensures the components are in good condition before installation. Charging the train is typically considered part of the pre-operation tasks, ensuring that the train has the necessary electrical power for operation. Applying handbrakes is crucial for ensuring the train remains stationary while maintenance or installation is taking place.

Thus, the step of removing all power contributes directly to safety and is a foundational aspect of the installation process, making it an integral part. Therefore, identifying this step as one that is NOT part of the installation process does not align with the correct safety measures that must be followed.
