Switchboard load schedule fields
Field list for recording Australian switchboard load schedule inputs before using load and maximum-demand calculators.
Load schedule fields for switchboard records
Show the record fields needed for load schedules without prescribing a universal maximum-demand method.
| Field | Purpose | Typical source | Boundary |
|---|---|---|---|
| Board reference | Ties the schedule to a real switchboard. | Drawings or board schedule | Do not combine boards without a clear record. |
| Load group | Separates lighting, socket, mechanical and dedicated loads. | Load schedule or design note | Grouping affects interpretation. |
| Phase allocation | Shows L1, L2 and L3 placement. | Circuit schedule | Phase allocation must be checked before balancing. |
| Connected load | Records load before demand treatment. | Nameplate, schedule or design load | Connected load is not automatically demand load. |
| Demand factor source | Keeps the entered factor traceable. | Project reviewer or governing source | This table does not publish universal factors. |
- Use the table to make maximum-demand inputs traceable.
- Final demand assessment remains a project and standards review task.
Before demand checks reach the calculator
Capture each circuit and load assumption consistently so maximum-demand and phase-balance results can be checked against the schedule.
| Item | Value |
|---|---|
| Purpose | Show the record fields needed for load schedules without prescribing a universal maximum-demand method. |
| How to use the source | Field table only; demand arithmetic lives on the maximum-demand calculator. |
| Standards and project context | AS/NZS 3000 maximum-demand context noted for project review; verify current rules and authority requirements. |
| Where judgement is still needed | Use this table for lookup, labelling or worksheet context; do not treat it as a project-specific calculation result. |
| Before relying on it | Confirm current standards, local authority requirements, DNSP conditions, project documents and manufacturer data before relying on a decision. |
Standards basis for load schedule fields
Keep the standards context, checked date and switchboard scope visible beside the schedule fields.

| Source type | AUWiring field model with standards context |
| Derivation basis | AUWiring worksheet field table; no controlled demand-factor tables are reproduced. |

| Review interval | Annual or when maximum-demand fields, project-record practice or standards context changes. |
| Review trigger | Calculator field change, standards update, authority context change or project feedback. |

| Australian application | Australia; project and authority context can override worksheet structure. |
