🔍 Key Concepts

• Order of making and breaking electrical connections for safety • Purpose of a ground (earth) connection on high-voltage equipment • Risk of creating a live, ungrounded common point while you are handling leads

💭 Think About

• If something becomes energized while you are installing the strap, which point would you want to be solidly connected to the hull first? • When removing the portable grounds, should you reverse the order of how you installed them for safety? What does that imply about the safest order for installation? • Which sequence avoids having your hand or body be the only path to ground if a phase becomes live unexpectedly during connection?

✅ Before You Answer

• Which step ensures the ground reference (hull) is established before any phase conductors are tied into the common point? • Which options would ever leave the common point floating (not solidly grounded), even momentarily, while a phase might be connected? • Confirm which sequence is standard in electrical safety practice: ground first or last when applying safety grounds.

Question 1 of 20

Connect the phase connections to common first, then connect the common connection to hull ground.

The common to hull ground connection and the phase connections to common should all be made simultaneously.

The common to hull ground connection and the phase connections to common can be made in any sequence.

Connect the common connection to hull ground first, then connect the phase connections to common.
