About this app
The Maximum Demand Calculator is a practical tool designed for electricians, designers, and industry professionals working to Australian and New Zealand standards. Built around the AS/NZS 3000 (Wiring Rules) methodology, this app helps you quickly and accurately calculate the electrical maximum demand for an installation using the C1 and C2 tables.
Perfect for residential, commercial, and industrial scenarios, the app removes manual lookup mistakes and streamlines compliance calculations—saving time and improving accuracy on every project.
◼ Accurate AS/NZ 3000‑Based Maximum Demand Calculations
The app uses the recognised C1 and C2 table methods from the AS/NZS 3000 standard to help determine maximum demand. It supports:
C1 Table calculations for fixed appliance loads
C2 Table calculations for socket‑outlet and general‑purpose circuits
Diversity adjustments according to the Wiring Rules
Combined installation load assessments
Single‑phase and three‑phase systems
Whether you're sizing supply cables, assessing switchboard loading, or preparing certification paperwork, the app helps ensure your calculations remain consistent with industry expectations.
◼ Auto‑Generated PDF Reports
Create clean, professional PDF output for:
Job records
Compliance documentation
Customer handovers
Audit or inspection notes
Long‑term installation history
Each PDF includes your calculated maximum demand values, input data, job details, and notes—ideal for electricians who need reliable documentation without extra admin time.
◼ Simple, Fast & Professional
Designed with electricians in mind, the interface is clean and efficient:
Easy‑to‑use input fields
Clear results for maximum demand
