Electrical distribution requirements
Data-centre electrical distribution is defined by the project redundancy concept, source arrangement, critical-load classification and monitoring requirements. Zejiefu can review switchgear and distribution-board scope from approved documents, but does not claim a facility tier, availability level or certification that has not been independently verified.
Typical equipment scope
- Main LV switchgear for approved A and B distribution paths
- ATS or transfer panels for defined operating sequences
- Boards for mechanical, utility and critical support loads
- Metering and communication provisions specified by the project
Project information to provide
- Approved SLDs and redundancy narrative
- Load schedules and source capacities
- Protection coordination and fault levels
- Monitoring protocol and required status points
- Testing, witness and documentation requirements
Engineering and delivery workflow
The review focuses on source boundaries, interlocking, feeder identification, maintainability and monitoring points. Approved drawings and control narratives are required before manufacture. Factory inspection records are provided where included in the confirmed supply scope.

Prepare the RFQ documents
Use the SLD and BOQ preparation guide to align ratings, feeder references, installation requirements and document revisions before submitting the project.
Frequently asked questions
Does Zejiefu determine the data-centre redundancy level?
No. Redundancy, availability and facility classification must be defined by the responsible project designer. Equipment is configured to the approved documents.
Can monitoring points be included in the switchgear scope?
Yes. Required meters, status contacts and communication interfaces should be listed in the monitoring schedule or control narrative.
