With the increase introduction of polystyrene and polyurethane panelling in general and domestic construction it is worth noting that if wiring a fixed installation with standard TPS there is no rule requiring the use a non-migratory cable.
However, as per AS/NZS 3001.2.2022 Electrical Installations-Connectable Electrical Installations and Supply Arrangements ( Part 2 : Connectable Electrical Installations ), which covers installations such as dongers, caravans and trailers, Clause 3.7.4.2 specifies the requirement for non-migratory cable to be used.
When working on a building with Polystyrene and Polyurethane Panels, it's advisable to inform the builder about potential long-term issues that may arise from using standard TPS cable. While non-migratory cable is slightly pricier than standard TPS cable, its usage could prevent future complications.
