# Common mistakes (/docs/form-guides/electrical/nsw/nsw-ccew/common-mistakes)



Common mistakes when completing a NSW CCEW, and how to avoid them.

Use this page to check records from an existing draft. Complete every new CCEW directly in the BCNSW eCert portal.

<Callout type="warn" className="docs-callout-warn my-4">
  Tradie Forms does not provide the new CCEW or direct eCert lodgement. A legacy draft is a historical reference, not a current certificate.
</Callout>

## Data entry and validation [#data-entry-and-validation]

### 1. Incomplete testing documentation [#1-incomplete-testing-documentation]

**Mistake:** Missing or incomplete test results, especially insulation resistance, earthing, and RCD tests.

**How to avoid:**

* Perform all required tests on site before certifying
* Record measured values (e.g. insulation resistance in MΩ) from calibrated equipment
* Use **Check All** only when every listed test was actually performed
* Complete the **Test report** section before **Certification**

<Callout type="warn" className="docs-callout-warn my-4">
  Form validation does not replace physical testing. Test the installation using the standards and job requirements that apply to your work.
</Callout>

See [Test report](/docs/form-guides/electrical/nsw/nsw-ccew/test-report).

### 2. Address errors [#2-address-errors]

**Mistake:** Wrong or incomplete addresses for customer or installation site.

**How to avoid:**

* Confirm customer address vs installation site. They are separate fields
* Cross-reference with the job file, contract, or electricity bill
* Complete all required components: street number or lot/RMB, street name, suburb, state, postcode
* For rural properties, verify lot/RMB numbers with council or title documents

See [Customer](/docs/form-guides/electrical/nsw/nsw-ccew/customer) and [Installation](/docs/form-guides/electrical/nsw/nsw-ccew/installation).

### 3. Outdated licence details [#3-outdated-licence-details]

**Mistake:** Expired or incorrect installer or tester licence numbers and dates.

**How to avoid:**

* Check licence expiry before signing the certificate
* Verify contractor and qualified supervisor numbers against current NSW records
* Renew stored details after every licence renewal. Do not copy old certificates blindly

See [Installer](/docs/form-guides/electrical/nsw/nsw-ccew/installer) and [Tester](/docs/form-guides/electrical/nsw/nsw-ccew/tester).

## Technical specification errors [#technical-specification-errors]

### 4. Equipment and work detail inaccuracies [#4-equipment-and-work-detail-inaccuracies]

**Mistake:** Wrong equipment ratings, quantities, or work scope documented.

**How to avoid:**

* Tick only equipment categories where work was performed
* Record rating and number installed for each selected category
* Use **Particulars** for model numbers and non-standard configurations
* Align load calculations with installed equipment

See [Equipment](/docs/form-guides/electrical/nsw/nsw-ccew/equipment).

### 5. Meter and load errors [#5-meter-and-load-errors]

**Mistake:** Missing meter rows when metering work was done, or incorrect tariff/load figures.

**How to avoid:**

* When replacing meters, record both removed and installed meters
* Match meter numbers and readings to the physical meters on site
* Confirm estimated load increase reflects new circuits and appliances

See [Meters](/docs/form-guides/electrical/nsw/nsw-ccew/meters).

### 6. Treating a draft as a submission [#6-treating-a-draft-as-a-submission]

**Mistake:** Finishing a Tradie Forms draft but not submitting the current CCEW in eCert.

**How to avoid:**

* Enter and check the current details in eCert
* Submit as soon as possible and no later than seven days after completing the tests
* Save the eCert confirmation or reference with the job

<Callout type="warn" className="docs-callout-warn my-4">
  Legacy drafts may show a serial field or helper. Do not treat that as the current eCert reference or submission process.
</Callout>

See [Certification](/docs/form-guides/electrical/nsw/nsw-ccew/certification).

## Network and provider errors [#network-and-provider-errors]

### 7. Incorrect network service provider [#7-incorrect-network-service-provider]

**Mistake:** Wrong electricity distributor or relying on a legacy provider email field.

**How to avoid:**

* Confirm the distributor against the customer's electricity bill, not postcode alone
* **Ausgrid:** Sydney, Central Coast, Hunter
* **Endeavour Energy:** Greater Western Sydney, Blue Mountains, Southern Highlands
* **Essential Energy:** Regional and rural NSW
* Confirm the required parties and delivery details in eCert
* Check the customer email carefully because eCert uses it to provide their copy

See [Installation](/docs/form-guides/electrical/nsw/nsw-ccew/installation).

## Quality assurance [#quality-assurance]

### 8. Skipping the eCert review [#8-skipping-the-ecert-review]

**Mistake:** Submitting without checking all sections against the job file.

**How to avoid:**

* Review customer, installation, equipment, meters, installer, tester, test report, and certification in order
* Compare the completed eCert to your site notes before submitting
* Confirm the compliance declaration reflects work you personally verified
* Save the confirmation and check the customer's copy went to the right email

<Callout type="success" className="docs-callout-success my-4">
  Treat the cert as an official record. Every field should match what you did on site.
