🔍 Key Concepts

• Autotransformer (reduced-voltage) starters are used to limit high inrush current on larger motors. • The one-line diagram shows different starter types: note the difference between LVP, LVR, and the “RED‑V” notation. • Compare the motor sizes (HP / kW) and the protective device ratings (AT/AF) for each load.

💭 Think About

• Which load on this diagram would draw the highest starting current if started across-the-line, based on its horsepower? • Which cubicle shows a reduced-voltage feature in its labeling or symbology that would normally be associated with an autotransformer starter? • Why would a cargo-related motor sometimes need limited starting current and torque compared with small service pumps or treatment plants?

✅ Before You Answer

• Match the largest HP motor with the corresponding feeder on the diagram. • Identify which LVP/LVR unit includes the “RED‑V” (reduced voltage) indication and think about what type of starter that implies. • Verify which answer choice matches the motor fed from the cubicle that likely contains the reduced-voltage (autotransformer) starter.
