Normal operation
Source and distribution
Map the normal supply route and identify the equipment that supports critical operations. Load growth, distribution boundaries and monitoring points form part of the same review.

Critical power systems
Continuity is a system decision.
THE SYSTEM VIEW
Continuity is a system decision.
Reliable power depends on the relationship between loads, supply routes, backup equipment and operating procedures. A coordinated review considers normal operation, an interruption and maintenance activities together, rather than treating availability as a single equipment feature.
The final configuration depends on the site requirements, the equipment available and the agreed scope of work. Interface planning connects those decisions with installation, testing and the information needed for operation.
CONNECTED LAYERS
Explore the system interfaces
Select a layer to see how it connects to the wider installation.
Supply interruption
Backup and transfer
Consider the permitted interruption and required autonomy for each load group. Coordinate the intended backup arrangement with the electrical design and equipment capabilities.
Planned intervention
Isolation and maintenance
Examine how equipment can be inspected, serviced or replaced. Define operational instructions and responsibility for authorising changes between operating modes.
Design review priorities
Understand the load
Identify critical functions, expected demand, starting characteristics and future expansion.
Review operating modes
Describe normal supply, backup operation, transfer and maintenance conditions with the project designer.
Keep an operating record
Preserve settings, inspection results and clear instructions for the personnel who manage the installation.
BEFORE HANDOVER
Make the interfaces reviewable
An interface register should identify each connection, the information needed to complete it and the party responsible for verification. Keeping this record current gives installation and commissioning teams a common reference when equipment or site conditions change.
At acceptance, drawings and equipment schedules should reflect the delivered arrangement. Test records, settings and agreed operating instructions then provide a useful starting point for maintenance and future modifications.
