Keep TCA1 Copies One Year: ACMA Cabling Rules for On Site Cablers

September 25, 2026
Keep TCA1 Copies One Year: ACMA Cabling Rules for On Site Cablers

If you perform or supervise cabling work in Australia, you operate under the Telecommunications (Cabling Provider) Rules 2025 and AS/CA S009:2020, the Wiring Rules, plus product standards under AS/CA S008 and the 2025 Technical Standard. Every job needs a written certification statement using the TCA1 or TCA2 form, kept on file for at least one year. ACMA is the regulator to check whenever a rule seems ambiguous on site.

TL;DR:

  • All cabling must maintain separation from electrical wiring along the entire run to prevent interference and electrical hazards, verified with photos before closing up the ceiling.
  • Only products with valid TLN labelling and appropriate datasheets can be used, with supplier documentation kept readily available for audits.
  • Certified cablers must personally perform or supervise all work, produce a certification statement promptly after completion, and keep records for at least one year.
  • Subcontracting work or working outside registered categories can lead to suspension or revocation of licensing, especially if certification or product labels are missing.
  • Building compliance into everyday practice involves verifying product labels and test results during installation and automating certification documentation to avoid delays.

How Do the Wiring Rules Govern On-Site Installation?

AS/CA S009:2020 applies to customer cabling on the customer side of the network boundary, covering fixed and concealed cabling in homes, offices, and rural sites. It kicks in the moment you touch permanent cabling infrastructure, whether that's a new install or a repair to existing runs.

Separation from electrical wiring is the single most cited compliance failure on inspection reports. The Wiring Rules set minimum clearances between telecommunications cabling and mains electrical cable to prevent induced interference and, more seriously, electric shock risk to anyone touching a phone jack or data port.

Key obligations under AS/CA S009:2020 include:

  • Maintaining separation distances from electrical cabling at all points along a run, not just at the termination
  • Routing cable away from heat sources, sharp edges, and areas prone to moisture ingress
  • Testing every completed run for continuity, polarity, and signal performance before calling the job finished
  • Documenting test results so they can support the certification statement required under the Cabling Provider Rules

Pro Tip: Photograph separation distances at rooftop and subfloor penetrations before you close up the ceiling. It takes thirty seconds and saves hours if a building manager questions the install later.

What Product Standards Apply Under AS/CA S008?

AS/CA S008 sets the technical bar for cables and connecting hardware used in customer cabling, covering things like insulation performance, fire behavior, and electrical characteristics. ACMA adopted this standard into the Telecommunications (Requirements for Customer Cabling Products) Technical Standard 2025, which means using non-compliant gear isn't a paperwork technicality. It's a breach of the same rules that govern your registration.

Every compliant product carries a Telecommunications Labelling Notice (TLN) mark, either on the item itself or its packaging. Before you install anything, verify:

  • The supplier can produce a compliance declaration or TLN documentation on request
  • Cable jacketing and connector housings show the correct labelling, not a generic import sticker
  • Product datasheets match the application (indoor versus outdoor rated, plenum versus standard)

Keep supplier invoices and any compliance certificates in your job file. If ACMA or a registrar ever audits a completed installation, unlabelled cable is the fastest way to turn a routine job into a compliance investigation.

What Do the Cabling Provider Rules 2025 Require?

The Telecommunications (Cabling Provider) Rules 2025 replaced the 2014 version and commenced in March 2025, and they're the legal backbone behind every registration category in the industry. Under the CPRs, a registered cabler must either perform the work personally or directly supervise it, ensure the finished installation complies with the Wiring Rules, and prepare a written certification statement for every completed job.

Core obligations include:

  • Performing or directly supervising all regulated cabling work covered by your registration
  • Preparing a certification statement as soon as practicable after finishing the job
  • Retaining a copy of every certification statement for at least one year
  • Cooperating with ACMA inspectors and registrars, including producing records on request

Penalties for non-compliance range from formal warnings to suspension or outright revocation of registration. Repeated breaches, falsified certification statements, or working outside your registered category can end a career fast, not just a single job.

Which Registration Type Do You Actually Need?

Registration comes in three flavors, and picking the wrong one is a common early career mistake. Each has its own scope and its own competency evidence trail.

  1. Restricted registration covers basic cabling work like simple extensions and single-line installations, and typically requires around a modest amount of documented on-the-job experience.
  2. Open registration covers the full range of customer cabling work, including complex structured cabling and multi-line systems, and generally calls for closer to a substantial amount of experience under supervision.
  3. Lift registration is a narrow category for cabling installed inside lift wells and shafts, treated separately because of the unique access and safety conditions involved.

All three require passing a cabling regulation test, with an 80 percent pass mark, before a registrar will approve the application. Specialized work, fibre optic termination, coaxial systems, or complex structured cabling, often demands additional competency units on top of the base registration, so check the specific unit codes your registrar lists before assuming your Open ticket covers everything.

How Do You Complete a Valid TCA1 or TCA2 Statement?

Every job needs a certification statement, and ACMA's TCA1 form is the standard template, though you can build your own version as long as it captures the required fields: the cabler's registration number, the work performed, the address, the date, and confirmation of Wiring Rules compliance.

Timing matters more than most cablers realize. The statement should be prepared as soon as practicable after the work finishes, not weeks later when you're catching up on paperwork. Give a copy to the customer, give a copy to your employer if you're not self-employed, and keep your own copy for at least one year.

  • Use TCA2 instead of TCA1 when you discover a pre-existing non-compliant installation you didn't cause
  • Notify the building manager or owner in writing when TCA2 applies, especially in multi-tenant buildings
  • Attach the statement to the invoice if that's easier, provided every required field is still present

Pro Tip: Build a TCA1 template into your invoicing software so the certification statement generates automatically the moment you close out a job. Waiting until end of week is how fields get forgotten.

What Must Supervisors Verify Before Signing Off?

Supervisor inspecting completed cable termination

Direct supervision means physically overseeing the work, not just being contactable by phone. If an unregistered worker installs cabling under your supervision, you carry full responsibility for that work when you sign the certification statement.

Before signing, confirm the worker followed separation and routing rules, all products carry TLN labelling, and every run passed testing. Check that the worker's experience hours are being logged correctly if they're building toward their own registration.

  • Verify test results personally rather than relying on a verbal "it's fine"
  • Retain training records and experience logs for every unregistered worker on your crew
  • Store certification copies, test sheets, and product compliance documents together by job number for at least twelve months

What Does a Pre and Post-Job Compliance Checklist Look Like?

A simple sequence keeps most jobs audit-proof without slowing anyone down.

  1. Before starting: confirm your registration category covers the scope of work, and check any specialized competency units required for fibre or coaxial elements.
  2. Before installing: verify every cable and connector on site carries valid TLN labelling and matches the application.
  3. During installation: maintain separation distances from electrical cabling and route around heat and moisture hazards.
  4. After installation: test every run for continuity and performance, and record results in the job file.
  5. Before leaving site: issue the TCA1 (or TCA2 for pre-existing faults), distribute copies to customer and employer, and file your own copy.

Pro Tip: Keep blank TCA1 and TCA2 forms in your vehicle, not just on a tablet. A flat battery shouldn't be the reason a certification statement gets delayed a week.

How Accredited Installers Build Compliance Into Everyday Jobs

Compliance works best when it's a habit baked into the job, not a form filled out under pressure at the end. Professional installers build product verification and testing into the scoping stage of every structured cabling and networking project, checking TLN labelling and supplier documentation before a single cable goes in the wall.

That approach carries through to handover. Rather than treating certification as an afterthought, the process includes:

  • Documented product compliance checks recorded against each job file
  • Full continuity and performance testing before any run is signed off
  • A certification statement and commissioning notes handed to the client at completion, not weeks later

A Supervisor's View on Where Compliance Actually Breaks Down

Most compliance failures I see trace back to delay, not ignorance. A supervisor means to write the certification statement "tonight" and it slips a week, then the details get fuzzy. Unlabelled product and missing registration evidence are the other repeat offenders, usually because nobody checked the box before the van left the yard. The fix is boring but effective: spot-check labelling on every job, keep TCA forms within arm's reach, and certify before you drive away, not after.

Want a Registered Installer to Handle the Compliance Paperwork?

Chasing down TLN labelling, running continuity tests, and filing a TCA1 for every job is a lot to carry on top of the actual installation work. There are alternatives to piecing compliance together yourself: having every structured cabling, networking, and Wi-Fi project scoped, installed, and certified by a single licensed team without subcontractors, with a documented handover including product checks, test results, and certification statements ready for your records.

FAQ

What Are the Australian Cabling Standards?

The two core standards are AS/CA S009:2020, the Wiring Rules governing installation practice, and AS/CA S008, which sets product requirements for cables and connecting hardware. ACMA adopted AS/CA S008 into its 2025 Technical Standard, making product compliance a regulatory requirement rather than just an industry recommendation.

What Are the ACMA Standards in Australia?

ACMA enforces the Telecommunications (Cabling Provider) Rules 2025, which require registered cablers to follow the Wiring Rules, use compliant products, and issue a written certification statement for every job. These sit alongside registration categories, competency testing, and recordkeeping obligations detailed in the CPRs.

What Are the Standards for Cabling Installation?

Installation must meet AS/CA S009:2020, covering separation from electrical cabling, safe routing, and mandatory testing before a job is certified complete. Products used in the installation must separately meet AS/CA S008 and carry valid TLN labelling.

What Are the Requirements for Obtaining an Open Cabling Registration?

Open registration typically requires documented on-the-job experience of around 360 hours, plus a passing score on the cabling regulation test, set at an 80 percent pass mark. Applicants submit evidence and the test result through an ACMA-accredited registrar, who processes the application and issues the registration.

Who Should I Contact if I'm Unsure About a Cabling Rule?

ACMA is the ultimate authority on cabling regulation, and its cabling standards page is the starting point for official guidance.
