How long should an elevator be shut down before restarting the power?

The recommended duration for shutting down an elevator before restarting the power is designed to ensure that any residual issues, such as mechanical entrapments or electrical faults, are addressed before the equipment is reactivated. Shutting down the elevator for 10 seconds allows for system resets and can potentially clear minor faults. This brief duration is typically sufficient for many elevator systems to reset their controls and ensure that safety mechanisms have had time to engage properly.

Elevators are complex systems with multiple safety features, and the protocols for power restart procedures prioritize both passenger safety and equipment integrity. A short waiting period also helps in preventing damage that could arise from restarting an elevator that is still experiencing issues. The specific time frame can vary by manufacturer and type of elevator, but 10 seconds is a standard practice in many guidelines for ensuring an elevator is safe to operate again.
