Automatic transfer switches should be tested monthly to ensure proper functioning. Testing the switch requires the switch be electronically switched from the normal position to the alternate position or power position. In cases where there is no built-in testing feature, this must be done manually by disconnecting normal power and switching to alternate power.
Transfer switches must be maintained and placed in dust and dirt free areas in order to ensure the switch’s contacts remain functional.
In order to assure that your transfer switches remain in effect and timely when called upon, they should annually be inspected.
