🔍 Key Concepts

• Look at the horizontal axis labeled "current x FLC" (full‑load current) and identify where the motor current curve starts at time zero (locked rotor condition). • Understand that locked rotor current is typically several times the full‑load current; this graph shows that multiplier directly. • Multiply that current multiplier by the given 25‑amp full‑load rating to estimate the locked rotor current.

💭 Think About

• On the motor current curve, at the very beginning of the start (near the top of the left side), what value on the "current x FLC" axis does it align with? • If the full‑load current is 25 amps, and the graph shows the starting current is some multiple of FLC, what approximate ampere value does that represent? • Compare your calculated amperes to the answer choices: which one is closest to your calculated locked rotor current?

✅ Before You Answer

• Be sure you are reading the motor current curve, not the OCR or fuse curves. • Confirm the current multiplier is read from the bottom horizontal scale (1 to 10 times FLC), not from the time axis. • Verify your final number is several times higher than 25 amps, consistent with typical locked rotor behavior.
