Load Break Disconnect Switch Inspection Checklist

A load break switch, or a disconnector or disconnect switch, can serve as enclosures for overcurrent protection and ground fault protection. Ensure that the switches are maintained and are functioning properly by performing visual inspections and mechanical testings using this form. Check that the switches are in their required operating position, that they are free of chips or cracks, and inspect the linkages and operating handles for signs of damage. Take photos of any visual defects and use the inspection results to inform corrective measures as necessary. This form is customizable to suit your inspection requirements and maintenance guidelines and works in both on and offline environments.
