2.5mm single core, double insulated cable on a 100m drum. Red PVC inner with a separate PVC outer sheath over a single copper conductor. Used where mechanical protection and double-insulation rating are needed without the bulk of orange circular. Manufactured to AS/NZS 5000.1.
Used for GPO subcircuit actives and neutrals where additional insulation protection is needed beyond standard building wire — conduit runs, mechanical-risk installations, and switchboard wiring. SDI is a workhorse for residential and light commercial sub-mains where the installation passes through wall cavities or ceiling spaces and needs the additional insulation layer. Also common for short consumer mains and sub-mains to detached garages, granny flats, and secondary distribution boards.
Licensed installation per AS/NZS 3000. 2.5mm² SDI typically protected at 20A on GPO circuits. Confirm installation method derating and group factor. The red colour identifies this as active conductor (single-phase A phase or active under traditional Australian colour scheme) — verify your installation's colour scheme matches the wiring rules in force.
