HT & LT Electrical Systems:
7 Checks Before Handover

Project handover is more than energising a panel. A dependable electrical installation needs coordinated inspection, testing, documentation and a clear record of what was commissioned. The exact checks depend on the project, equipment and applicable standards, but the following seven areas provide a useful starting point.

1. Verify panels and equipment

Check panel identification, ratings, physical condition, clearances, gland plates, earthing connections, busbar arrangements and equipment labels. Confirm that installed equipment matches the approved drawings and project schedule.

2. Inspect cable routing and termination

Review cable routes, supports, segregation, bend radius and protection. At termination points, verify correct lugs, glands, ferrules, torqueing and phase identification. Keep cable records aligned with the as-built documentation.

3. Check earthing and bonding

Verify that equipment and relevant metallic parts are bonded as required by the project design. Earthing continuity and resistance measurements should be tested using appropriate instruments and recorded in the commissioning documentation.

4. Test protection and control functions

Protection devices, interlocks, indication and control functions should be checked against the approved design and equipment requirements. Where relay settings or protection coordination studies apply, verify that the installed settings are documented and authorised.

5. Perform pre-energisation checks

Before energisation, complete the project-specific safety and readiness checklist. Confirm that temporary connections are removed, covers are secured, warnings are in place, access is controlled and the responsible team has completed the required checks.

6. Commission under controlled conditions

Commissioning should be planned so that each stage can be verified before moving to the next. Record readings and observations for transformers, panels, feeders and other equipment included in the project scope. Any abnormal result should be investigated before final handover.

7. Close documentation and handover

A professional handover package can include test reports, equipment schedules, cable schedules, approved as-built drawings, settings, manuals, warranty information and maintenance recommendations. The exact document set should follow the contract and project requirements.

Final thought

Electrical reliability starts with disciplined installation and continues through testing and maintenance. A structured handover helps the facility team understand what was installed, what was tested and how the system should be maintained.
