# Meters

> Record meter installations, load calculations, and supply information for electrical work

This section documents meter changes, load calculations, and supply connection details. Accurate job details are essential for network operator records, billing accuracy, and grid capacity management.

## Meter management

The meter section tracks all metering changes associated with the electrical work, supporting up to 8 meters per job.

<Tip>
  When replacing meters, add both the old meter (status: "Removed") and new meter (status: "Installed") to maintain complete installation records.
</Tip>

### Adding and managing meters

<Steps>
  <Step title="Add meters">
    Click "Add Meter" to create a new meter entry. The system supports up to 8 meters per CCEW.
  </Step>

  <Step title="Set meter status">
    For each meter, select the appropriate status:

    * **Installed:** New meters added during the work
    * **Removed:** Existing meters removed during the work
    * **Existing:** Meters already present and unchanged
  </Step>

  <Step title="Remove unnecessary entries">
    Use the "Remove" button in the top-right corner of any meter card to delete unwanted entries.
  </Step>
</Steps>

### Meter specification details

For each meter entry, provide the following information:

<CardGroup cols={2}>
  <Card title="Identification" icon="id-card">
    * **Meter Number:** Physical meter serial number
    * **Register Number:** Specific register identification
    * **No. of Dials:** Total number of reading dials
  </Card>

  <Card title="Configuration" icon="settings">
    * **Master/Sub Status:** M (Master), S (Sub), or N (None)
    * **Wired as Master/Sub:** Physical wiring configuration
    * **Tariff:** Rate code (e.g., T11, T31, T33)
  </Card>
</CardGroup>

### Common tariff codes

Understanding tariff codes helps ensure accurate billing setup:

<Tabs>
  <Tab title="Residential">
    * **T11:** General domestic supply (single rate)
    * **T31:** Off-peak hot water heating
    * **T33:** Controlled load (pool pumps, storage heating)
  </Tab>

  <Tab title="Commercial">
    * **T20:** Small business single rate
    * **T22:** Demand-based commercial rates
    * **T41:** Large commercial/industrial supply
  </Tab>
</Tabs>

<Info>
  **Meter Reading:** Record the current reading for billing continuity and consumption tracking.
</Info>

## Load and supply assessment

### Load calculation requirements

Accurate load assessment ensures grid stability and compliance with network capacity:

<Steps>
  <Step title="Calculate additional load">
    **Estimated Increase in Load (A/ph):** Calculate the additional electrical load in Amps per phase from new installations.

    <Tip>
      Include all new appliances, lighting, and equipment in your load calculation.
    </Tip>
  </Step>

  <Step title="Assess existing capacity">
    **Is increased load within capacity?** Evaluate whether existing electrical service can handle additional load:

    * **Yes:** Current installation/service capacity is adequate
    * **No:** Service upgrade or load management may be required

    <Warning>
      Exceeding service capacity can cause safety hazards and compliance issues.
    </Warning>
  </Step>

  <Step title="Document connection status">
    **Is work connected to supply?** Indicate current energisation status:

    * **Yes:** New work is connected and operational
    * **No:** Work awaits network operator inspection/connection
  </Step>
