What is this service?
Preparation of the electrical single line diagram, representing the distribution of power from the source (transformer or generator) through the main and sub-distribution boards down to the loads, showing breaker ratings, cable sizes and earthing. It is the primary reference for understanding, operating and maintaining the installation, and is issued approved to the Saudi Building Code.
Why do you need this service?
A single clear reference for the entire electrical installation.
Simplifies operation, maintenance and fault tracing.
A prerequisite for approval of the electrical drawing package.
Compliance with the Saudi code and international standards.

Frequently Asked Questions About This Service
What is a single line diagram for?
It represents the entire electrical installation on one page: from the transformer or generator through the main and sub-boards down to the loads, with breaker ratings and cable sizes — the first thing anyone reads to understand the system.
When do I need it after handover?
For maintenance, fault tracing or adding a new load, because it shows each board's supply source and capacity limits — saving considerable time compared with tracing cables on site.
Must it agree with the load calculations?
Yes. Breaker ratings and cable sizes on the diagram are checked against the load report for consistency; any discrepancy between them is raised as a technical comment at approval.
