🔍 Key Concepts

• Primary means of electrical isolation versus normal control devices • Difference between a disconnecting means and a control circuit device • Requirements for a device used to safely lock out and de-energize equipment for maintenance

💭 Think About

• Which of these devices actually opens the main power conductors with a positive, visible, and lockable disconnection? • Which option is normally used just to send a control signal (like "start" or "stop") but does NOT guarantee the power circuit itself is fully de-energized? • For safe maintenance, which device can you reliably lock and tag so no power can be restored accidentally?

✅ Before You Answer

• Verify which options are considered disconnecting means in electrical safety practice. • Check which device only acts on a control circuit and does not break the main power lines. • Confirm which device cannot be relied upon as the primary isolation when performing lockout/tagout.
