Before resetting an overload relay on a starter, you must ___.

Before resetting an overload relay, it is essential to find and correct the cause of the overload. Overload relays are designed to protect motors from overheating due to excessive current, which can occur for various reasons, such as mechanical failure, binding, or electrical issues. Simply resetting the relay without addressing the underlying cause can lead to repeated trips of the relay, potential damage to the motor, or even electrical hazards.

By identifying and resolving the issue that triggered the overload condition, you ensure that the motor operates safely and efficiently once power is restored. This proactive approach helps maintain the integrity of the electrical system and prevents future overload occurrences.
