The Australian Standard AZ/NZS3000 (the Wiring Rules) is being updated and will be published later this year.
Part of it will include some changes to the requirements of sleeving of conductors and clarification on the segregation of different electrical installations.
When alterations or repairs are conducted requiring new terminations or junctions to existing bare or green earth conductors, the conductors should be sleeved with green/yellow sleeving within each of the new cable junctions or terminations.
Similarly, where alterations or repairs are done on conductors with yellow insulation that require new terminations or junctions, all the conductors must be sleeved with white sleeving at each of those new cable junctions or terminations.
Requirements have been clarified for different electrical installations. 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.
