🔍 Key Concepts

• Follow the reverse order of how grounds are applied for high-voltage work (what gets connected first should be removed last). • Think about keeping the system safely connected to the ship’s hull ground for as long as possible during removal. • Focus on the roles of the individual ground straps to the motor terminals versus the single common hull ground connection in figure B.

💭 Think About

• When applying grounds originally, which point is safest to connect to first: the hull ground or the motor terminals? How does that affect the order you should disconnect them? • While removing grounds, which connection do you want to keep in place until the very end so the system is never left "floating" without a safe discharge path? • If you disconnected the hull ground first, what could happen to any remaining charges on the motor terminals and straps still attached to the common point?

✅ Before You Answer

• Be sure you know which clamp in the figure is the common hull ground connection and which are the motor terminal clamps. • Confirm which part provides the actual path to the ship’s structure: the common hull ground or the individual motor straps. • Before choosing, verify that your sequence keeps a continuous path to ground for as long as possible during disconnection.
