Maximum demand in Australian load worksheets
A workflow guide for preparing user-entered maximum-demand rows before using the AUWiring switchboard load calculator.
Worksheet purpose
Maximum demand work should leave a traceable row record. The calculator can add entered rows and show worksheet totals, but it does not decide every demand assumption for the project.
The useful result is a structured review record: load groups, current or power basis, entered demand assumptions, spare capacity notes and the next technical check for the project.
Workflow
- Prepare each load row before opening the calculator.
- Confirm the unit and source for current, kW or kVA.
- Enter demand or allowance assumptions as visible row values.
- Keep spare capacity and future allowance notes separate from present connected load.
- Review the result before carrying it into cable, switchboard or supply work.
Maximum-demand row fields
| Field | Purpose | Review point |
|---|---|---|
| Load group | Identifies the row owner | Avoid duplicate or missing loads |
| Entered value | Current, power or apparent power basis | Check the source and unit |
| Demand assumption | User-entered factor or allowance | Keep the basis visible |
| Phase basis | Single-phase, three-phase or grouped | Affects current and balance review |
| Review note | Standards, DNSP or design caveat | Prevents overclaiming the worksheet |
Reading the result
A maximum-demand result is a planning output. It can show whether entered rows produce a plausible worksheet total and where assumptions need review. It cannot confirm supply availability, switchboard suitability or final compliance by itself.
Use the phase-balancing calculator when single-phase row allocation matters. Use cable calculators when the demand current needs route or cable review.
Boundaries
- Do not hide demand assumptions inside unexplained totals.
- Do not copy fixed demand rules into public page text.
- Do not treat spare capacity as present demand.
- Do not describe a worksheet result as approval for installation.
Maximum demand in Australian load worksheets in Australian work
Show how to structure a maximum-demand worksheet so the calculator result remains a traceable planning record rather than a compliance claim. The useful record is not just the final number or definition; it is the combination of the entered value, the supply arrangement, the equipment or circuit reference and the decision that still needs project review.
Australian maximum demand workflow for user-entered switchboard load worksheet rows Keep the wording in Australian English, use metric units, and treat 230/400 V a.c. at 50 Hz as the ordinary low-voltage context unless the project information states a different value.

- Standards contextAS/NZS 3000 context noted for project review; current standards, authority requirements and project design records remain controlling sources.

Practical use sequence
For Maximum demand in Australian load worksheets, begin with the circuit, board, load, cable route, equipment item or measurement record named by this topic. Record the value basis, such as current, voltage, kW, kVA, route length, test value, product rating, tariff value or worksheet field, then note the review boundary so another person can see what this page explained and what still needs a project decision.
The strongest Maximum demand in Australian load worksheets record is specific enough to be reviewed later. It names the Australian context, keeps the entered assumptions visible, separates calculation support from compliance decisions and shows where a calculator, table, chart or term definition should be opened next.
Record detail to capture
Keep the Maximum demand in Australian load worksheets note attached to Australia; Australian English; project, DNSP, local authority, product and standards source documents can override worksheet assumptions.. When the page is used during design, estimating, testing, review or study work, write the entered assumption, the source that supplied it, the circuit or equipment label and the person or role that must review the following action.
For Maximum demand in Australian load worksheets, the review cadence is Annual or when maximum-demand fields, switchboard table rows or Australian standards context changes. and the update trigger is Calculator field change, switchboard table change, standards context update, DNSP/local authority update or project feedback.. If the topic connects to Maximum demand, open that page after the current definition, input basis or boundary has been recorded, so the next calculation inherits the right Australian context.
A complete Maximum demand in Australian load worksheets record leaves four facts visible: why the page was opened, which Australian supply or equipment context applies, which value remains user-entered and what later change would alter the result. That makes the page useful as a working note instead of a loose reference copied away from the project evidence.
- InputsWrite down the entered values and their units before comparing results across calculators or reference pages.
- LocationKeep the value tied to the board, circuit, cable run, equipment terminal, supply point or worksheet row it describes.
- Authority checkCompare the record with current Australian requirements, DNSP or local authority conditions and product information.
- Review trailRetain the date, edition context and reason for the calculation so later changes can be traced.
