Switchboard design.
Ready for manufacture.
Switchboard design and manufacturing documentation for New Zealand projects. We develop coordinated layouts, schematics and equipment schedules from your supply arrangement, loads and operating requirements, with the design deliverables agreed at quotation.

Layouts, schematics and equipment schedules
A clear design package connects the electrical specification with the physical assembly. Our work includes general arrangements, busbar layouts, power schematics and equipment schedules, with the scope agreed for each project.
Space for cable termination, access to devices, transport sections and future additions needs to be considered alongside electrical ratings. Identifying these requirements early reduces ambiguity when the board reaches manufacture.
Coordinate the physical and electrical design
EPLAN Pro Panel supports the development of the assembly layout in 3D. Component positioning, cable space and internal clearances can be reviewed alongside the electrical documentation before the board is built.
Heat dissipation, airflow and enclosure constraints also affect layout decisions. Required drawing formats, including PDF and agreed DWG or DXF deliverables, should be established at the start of the project.
Control revisions through manufacture
Approval comments and changes need a clear revision history. Agree who approves the design, the point at which manufacturing can proceed and how later changes will be incorporated into the final documentation.
Electrical analysis starts with the network.
PowerCAD network analysis can support load flow, short-circuit, voltage-drop and protection-coordination work within an agreed design scope. Useful results depend on reliable source, transformer, cable, load and protection data.
Confirm the designer’s responsibilities, study boundaries and required outputs. Supply authority information, protection settings and operational switching arrangements should be coordinated with the responsible project parties.
