Protective devices such as relays, overload coils and circuit breakers must be checked on installation and at regular intervals while in service to ensure that they are always ready to operate correctly if a fault should occur in the equipment that they are protecting. Routine testing will quickly detect faulty or incorrectly adjusted protection devices, and possibly prevent serious damage to equipment and injury to personnel.
