New requirements for sleeving of conductors

Tuesday, 05 September, 2017

The Australian Standard AS/NZS3000 (the Wiring Rules) is being updated and due to be published later this year.

It will include some changes to the requirements of sleeving of conductors and clarification on the segregation of different electrical installations, according to an update by the Queensland Electrical Safety Office.

“When alterations or repairs are carried out that require new terminations or junctions to existing bare or green earth conductors, all of those conductors need to be sleeved with green/yellow sleeving within each of the new cable junctions or terminations.”

Similarly, where alterations or repairs are carried out on conductors with yellow insulation that require new terminations or junctions, all those conductors need to be sleeved with white sleeving at each of those new cable junctions or terminations, states the update.

“For different electrical installations, the requirements have been clarified. This includes not allowing conductors to be installed in the same pipe, tube, conduit or the same multi core cable where the conductors form part of different electrical installations. This includes installations where conductors form part of individual occupancies of single or multiple electrical installations.”
