Switchboard Design,
Cost Estimation & Engineering.
Specialist switchboard drafting, comprehensive cost estimation, compliance calculations, and engineering support for Australian manufacturers. Built strictly to AS/NZS 61439 and AS/NZS 3000.
AutoCAD & SolidWorks Drafting
General Arrangement, Single Line Diagrams, and tier elevation schedules.
Full Cost & BOM Estimation
Copper busbar weight, enclosure sizing, and breaker selection within 48h.
Engineered Strictly to AS/NZS 61439 & AS/NZS 3000
Australian switchboard compliance demands rigorous verification. We calculate, check, and cross-reference every design parameter before drafting begins.
Temperature Rise Verification
Calculations per AS/NZS 61439.1 Clause 10.10 ensuring internal ambient temperatures and terminal limits remain safe under full load factor.
Short-Circuit Withstand
Verification of busbar bracing, supports, and electrodynamic stress calculations to withstand specified Icw / Ipk fault levels.
Form of Segregation
Precision partitioning designs for Form 1, Form 2a/b, Form 3a/b, and Form 4a/b configurations to guarantee operational isolation.
Clearance & Creepage
Strict adherence to insulation coordination, dielectric properties, and environmental pollution degree spacing requirements.
Comprehensive Design & Estimating Solutions
From tender stage bills of quantities to fabrication-ready manufacturing drawings for CNC punching and busbar folding.
Estimating & Tender Support
Never lose a bid due to estimating backlogs. We convert consulting specifications and single-line diagrams into fully costed estimates within 48 hours.
