MotorsQuestion 1300 of 1506

Why should a resistance split-phase motor not be restarted often or used on slow-starting loads?

  1. The centrifugal switch wears out after a single start.
  2. The main winding is too small for repeated starts.
  3. The thin starting winding heats up fast.
  4. The start capacitor overheats after the first start.
Show answer

Correct answer: The thin starting winding heats up fast.

The thin winding gets hot quickly when it stays in circuit.
