Core Design Capabilities
Electrical Design That Delivers Certainty
We provide end-to-end electrical design and engineering support — from early concept and load studies through to detailed drawings, switchboard design, protection coordination, and compliance packages.
Power Systems Design
Complete electrical power system design including load calculations, single-line diagrams, cable sizing, protection schemes, and distribution architecture.
Switchboard & Control Design
Detailed switchboard design, control schematics, MCC layouts, and integration of metering, monitoring, and automation systems.
Compliance & Documentation
AS/NZS compliant drawings, design reports, certificates, and technical documentation prepared for council, network, and construction approval.
Why Clients Choose Us
Design That Reduces Risk & Accelerates Delivery
Standards-Driven Engineering
Every design is developed against current Australian standards (AS/NZS) with clear consideration for safety, maintainability, and future expansion.
Construction-Ready Packages
We deliver clear, coordinated drawings and documentation that reduce RFIs, minimise site variations, and support smooth installation.
Integrated with Renewables & Controls
Designs that properly integrate solar, battery, EV charging, generators, and energy management systems from day one.
Ongoing Project Support
We stay involved through tender, construction, and commissioning — answering queries and refining designs as the project evolves.
Our Design Process
From Concept to Construction-Ready Design
1. Project Brief & Requirements
We capture load requirements, site constraints, future expansion plans, compliance needs, and integration with existing or planned energy systems.
2. Concept Design & Load Analysis
Preliminary single-line diagrams, load studies, and high-level architecture options are developed so decisions can be made early and with confidence.
3. Detailed Design & Engineering
Full detailed design: cable schedules, protection coordination, switchboard layouts, control schematics, earthing, and equipment specifications.
4. Documentation, Review & Support
Issue of design packages, design reports, and ongoing technical support through approval, tender, and construction stages.
Ready for Clear, Compliant Electrical Design?
Whether you need power systems design for a new build, switchboard upgrades, renewable integration, or full compliance documentation — Renostain delivers precise, construction-ready electrical engineering.
