What is the first step in installing bus jumpers?

The correct first step in installing bus jumpers is to apply handbrakes. This is a critical safety measure, as it ensures that the equipment is stable and will not move during the installation process. Applying handbrakes creates a safe working environment for personnel, helping to prevent accidents or injuries that could result from unexpected movements.

When handling electrical equipment or making modifications such as installing bus jumpers, ensuring the area is secure and that all necessary safety protocols are followed is paramount. By applying handbrakes first, you minimize the risk of equipment shifting, which could lead to unsafe conditions while you work on the jumpers.

Inspecting jumpers for damage, opening the receptacle, and restoring power are important steps, but they should occur only after ensuring that the installation site is secure, which starts with applying the handbrakes.
