Supply, power and load
Concept articles for Australian supply context, power units, load current and maximum-demand records.
Supply, power and load project basis
Concept articles for Australian supply context, power units, load current and maximum-demand records. These articles clarify Australian electrical terminology, supply assumptions and equipment context before the topic is applied in calculators, tables, charts or project notes.
More
Confirm the nominal 230/400 V a.c. or project-specific voltage basis, 50 Hz context where applicable, phase arrangement, metric units, manufacturer information, DNSP or authority conditions and current project documents before applying a result.
Check that the definition, supply basis, equipment label and project context still match the calculator, table or chart being used.

Review before applying
Supply, power and load articles explain terms and concepts before a calculator, table or chart is used. Keep the explanation connected to Australian terminology and the project record being prepared.
Recheck the selected article whenever the supply arrangement, equipment data, route length, tariff basis, measurement method or project document set changes.
