Residential Three-Phase Load Calculation

Job ID: 39706970

Budget: $10 – $30 AUD

I need a clear, professionally presented maximum-demand study for a new residential build that will be supplied by a three-phase service. The scope is confined to the heating and cooling equipment plus all lighting and general-purpose outlet circuits; kitchen and laundry loads are handled elsewhere, so they can be left out of your figures.

Please work through the accepted diversity factors for a contemporary home, document every assumption you apply, and show the step-by-step derivation that leads to the final kVA (or kW) figure for each phase and for the service as a whole.

Deliverables
• A concise load schedule or spreadsheet that lists connected loads, applied demand factors, and resulting demand per phase.
• A short explanatory note (PDF or DOCX) that walks through the calculation method and references the electrical standard or guideline you used.

Accuracy, clarity, and a format that lets me plug the numbers straight into my drawings are what matter most.
