Process Control Panels and Circuits Commissioning Checklist

1. Inspect for Physical Damage: Upon receiving the equipment, carefully inspect it for any physical damage that may have occurred during shipping. Report any damage following the shipper’s instructions.
2. Verify Nameplate Information: Compare the information on the equipment’s nameplate with the latest single line diagram and equipment specifications to ensure alignment and accuracy.
3. Wire Check and Connection Inspection: Conduct a wire check on power panels and lighting panels, ensuring that wiring is correctly in place. Clean the panel and inspect all connections, tightening them as needed.
4. Bonding Verification: Confirm that power panels and lighting panels are properly bonded to the transformer if applicable, ensuring secure electrical connections.
5. Neutral-Ground Separation: Verify that the neutral is not connected to ground within power and lighting panels. Ensure that the neutral is only grounded at the transformer, following proper electrical safety practices.
6. Conformity to Local Standards: Ensure that junction box covers, enclosures, condulets, wire trays, and similar devices meet local standards for environmental conditions and are correctly installed.

This checklist outlines the key steps for commissioning and ensuring the proper functioning of process control panels and circuits.
