Load structure
Separate critical, essential and general loads and identify motor starting or other demanding duties.
Solution planning
Secondary distribution
Structure low-voltage distribution requirements around loads, continuity, protection and panel arrangement.
At a glance
Secondary distribution
A useful low-voltage inquiry connects the load schedule to incomers, bus sections, outgoing feeders and operating priorities. This gives the technical team a clear basis for panel arrangement discussions.
Equipment selection
Match the equipment to the electrical system

Project information
- Load schedule and diversity assumptions
- System voltage, frequency and earthing arrangement
- Rated current and short-circuit requirements
- Incomer, coupler and feeder functions
- Form of separation, access and expansion needs
Selection details
Key considerations for this application
Continuity
Describe source arrangement, transfer expectations and the operating sequence for normal and abnormal conditions.
Panel integration
Identify metering, communication, control power and interfaces with building or process systems.
