Cable Covers (Tiger Tails) and Fault & Emergency Work

What is Happening?

There have been several instances recently where Level 2 ASPs, or in some cases unauthorised trade contractors, have fitted cable covers (tiger tails) to energised overhead service lines.
As a result of further investigation, it has been identified that confusion exists as to who is authorised to undertake this task. The WorkCover Code of Practice (CoP): Work Near Overhead Power lines provides direction in relation to the implementation of control measures for unauthorised persons working near low voltage overhead service lines.
Consideration should be given to Eliminating the hazard by deenergising the supply for the duration of the work, and where there is a danger of physical damage to the overhead service its temporary removal. Where this is not practicable, separating the hazard from the worksite may be achieved through the installation of insulating matting and tiger tails at the point of attachment.

Essential Energy’s response

Cable covers must only be fitted to energised service lines for the purposes of adherence to the CoP by electrically qualified Essential Energy authorised employees. ASPs and contractors are not authorised to carry out these tasks as this is not classified as Contestable Work, unless working on behalf of Essential Energy under the conditions of a contract can these be installed.

A Level 2 ASP can however, de-energise and remove a service line for the duration of the proposed works, or fit cable covers on a deenergised service line for mechanical protection and visual indication so long as the covers are removed prior to the installation being reenergised.
When de-energising a service line, the service connections at the Point of Common Coupling must always be disconnected and made safe. The service line should then be visually assessed to determine its condition. If it is not of sound condition or there are other factors preventing the service removal. The disconnected service is to remain in situ and covered with insulating matting and tiger tails for visual awareness and mechanical protection. Special attention should also be paid to protecting the consumer mains at the Point of Attachment.

If the service line is deemed to be in sound condition, and providing it is firstly disconnected at the Point of Common Coupling, then disconnect the connections at the Point of Attachment, remove the service from the attachment, and carefully roll up.

The completely disconnected service can then be secured where practicable to the non-trafficable side of the distribution pole or private pole at a minimum height of 4.6m. If this is not practicable or introduces other hazards, then the service should be removed and stored in a secure location ensuring no physical damage to the service is sustained.

Before re-energising, precautions must be taken to ensure that the service and electrical installation are in a state suitable for energisation and that all required testing (e.g. insulation resistance, polarity, neutral integrity and phase rotation) has been satisfactorily completed.

We would also like to remind ASPs are not to undertake any fault and emergency work on Essential Energy assets including services.
