Changes to the Telecommunications Cabling Advice (TCA1) form

The Australian Communications and Media Authority (ACMA) has recently updated the Telecommunications Cabling Advice form, commonly referred to as the TCA1 form.

ACMA has produced a supplementary form called a TCA2 which may be attached to the TCA1 form to alert customers or building owners of any non-compliant cable installations that they may not be aware of.

What is the TCA1 form?

The TCA1 form is a written advice to the customer or building manager on completion of a cabling job.  It provides details of the cabling work undertaken, together with the cabler's registration details and a signed declaration that the cabling work is compliant with the Australian Standard AS/ACIF S009:2006 (Wiring Rules).

However, cablers often encounter pre-existing (legacy) cabling in roof spaces and other concealed locations that is not compliant with the Wiring Rules.  Cablers are concerned that the customer or building owner may not be aware that these pre-existing cabling installations could pose a safety hazard or may affect performance.

What is the TCA2 form?

The TCA2 form is intended for use as an optional attachment to the TCA1, to alert customers and building owners of outstanding cabling issues that require their attention.

Advice to Cablers

Remember!  Cablers must fill in and sign a TCA1 form on completion of each cabling job.  

When filling out the form, cablers should describe their work clearly (specifying the type of work and location, for example, room, floor, section, department or building).

A copy of the form must be provided to the customer and your employer (if applicable). 

You must keep all copies of your TCA1 forms for at least 12 months and these must be made available to ACMA inspectors or cabling auditors on request.

You can make arrangements with your employer (if applicable) to keep your TCA1 forms on your behalf but, ultimately, you are responsible for them.

To avoid additional paperwork, you can incorporate the information on the TCA1 form into an existing invoice or other business documentation.
