A treadmill repeatedly trips its dedicated 20A circuit breaker under normal load. The most likely cause is:

  • AA console programming error in the speed settings
  • BExcessive current draw from a failing motor, high belt-deck friction, or an overloaded circuit
  • CIncorrect elevation angle programmed into the console
  • DA faulty speed sensor causing incorrect RPM readings

Correct Answer

Excessive current draw from a failing motor, high belt-deck friction, or an overloaded circuit

Explanation

Repeated circuit breaker trips indicate a sustained overcurrent condition. Check whether the circuit is shared with other loads first, then investigate belt friction, motor condition, and MCB output current.
