Factory electrical testing and commissioning involve checking the installation against project expectations and recording the results. Installation completion, functional verification and handover to the operating team should be treated as distinct control points. From the client's perspective, preparation starts at quotation stage by identifying the participants and the records required at each stage.
Factory electrical projects: testing, commissioning and handover
Factory electrical testing and commissioning involve checking the installation against project expectations and recording the results. Installation completion, functional verification and handover to the operating team should be treated as distinct control points. From the client's perspective, preparation starts at quotation stage by identifying the participants and the records required at each stage.
Define acceptance expectations at the start
Do not describe handover only as the completion of physical installation. Establish which systems will be reviewed, which records will be checked and how outstanding items will be closed.
Create a responsibility schedule for the client, contractor, design team and relevant equipment suppliers. For each system, identify who prepares, carries out, witnesses and evaluates the controls. Plan external organisation or operator involvement separately where required.
Distinguish inspection, measurement and functional checks
Initial verification of an electrical installation combines inspection with tests appropriate to the project. Schneider Electric's Electrical Installation Guide highlights reporting of inspection and test results, while recognising that requirements vary with local conditions and installation characteristics.
The approach in this article concerns the client's tracking of records and responsibilities. Qualified technical personnel must determine test methods, conditions and acceptance criteria using the project requirements, equipment manufacturer instructions and applicable rules. This article is not a procedure for carrying out site tests.
Link the test plan to the system schedule
A report should clearly identify the equipment or circuit to which it applies. Switchboard, circuit and system names should match the project references. Dates, results and responsible parties should be traceable.
A client-side tracking structure could include:
| Control point | Record to track |
|---|---|
| Installation review | Relevant drawing revision and work inspected |
| Measurement and testing | Results linked to equipment or circuit identifiers |
| Functional check | Function assessed and parties involved |
| Nonconformity | Outstanding item, responsible party and target date |
| Recheck | Result and evaluation after corrective work |
This is a project tracking tool, not a replacement for the technical test schedule.
Coordinate commissioning with the other teams
Electrical infrastructure, production machines and mechanical systems may be ready at different times. Make those dependencies visible in the commissioning programme. Agree the machine manufacturer's attendance and duties in advance where participation is needed.
Energising a system and verifying the expected functions of connected equipment are different milestones. Name the completed control point clearly in meeting records rather than using a general description such as “finished”.
Manage outstanding work through closure records
Keep a common list of issues identified before handover. Include location, system, description, responsible party and target date. State which document or recheck will demonstrate closure.
The responsible technical team should assess how each issue affects commissioning or handover. Photographs may help document an item, but a photograph alone does not establish technical acceptance. Record who made the decision and the evidence used.
Collect as-built drawings and operating documents
As-built drawings describe the installation as constructed. Separating superseded and current versions, matching equipment identifiers to site labels and keeping records accessible helps the operating team use the information.
Depending on the project, the handover file may cover current drawings, equipment information, inspection records, operating and maintenance documents, outstanding work and responsible contacts. The European Commission's Documentation and Commissioning guide also considers these document groups together. It is not a statement of Turkish legal requirements or a mandatory document checklist for every project in Türkiye.
Complete the handover with the operating team
Include the people who will operate the systems alongside procurement and site representatives. Agree where documents will be held, how equipment information can be found and who will track remaining work.

Frequently asked question
Are test reports alone enough for handover?
The decision depends on the contract and technical assessment. Review the coverage of the records, their match to the actual installation, outstanding items and other required handover documents together.
