The round ring track's power connection uses a module built for its specific geometry rather than a shared linear-track component — the T20CU-G, in 2-wire or 4-wire versions, linking the T20CU-J power supply to the ring at the ceiling mounting point.

This installs alongside the Surface Mounting Kit (T20CU-B) at the ring's connection point, forming the complete ceiling assembly that energises every fixture around the ring's circumference from that single feed. Wire count follows the same logic as the linear system: 2-wire for standard On/Off switched ring installations, 4-wire where the circuit carries an additional control signal for RF+BT app-controlled fixtures on the ring.

The distinction from the linear track's T20-G and T20-H worth stating plainly: these are not interchangeable products. Ordering the wrong one for a ring installation results in hardware that physically doesn't connect, since the round track's mounting geometry differs from the linear profile.

Can the linear track's T20-G or T20-H be used on a round ring installation instead?

No. The T20CU-G is built specifically for the round ring's connection geometry, which differs physically from the linear track profile. The T20-G and T20-H will not connect correctly to ring track hardware — always specify T20CU-G for a ring installation.

Because the round ring system's CU-series components are all specific to that track type, ordering this alongside the correct matching Power Supply (T20CU-J) and Mounting Kit (T20CU-B) as a coordinated set, rather than individually, reduces the risk of a mismatched component reaching site.

Should these CU-series components be ordered together as a set?

Yes, where practical. Ordering the Input Module (T20CU-G), Power Supply (T20CU-J), and Mounting Kit (T20CU-B) together as a coordinated set for a ring installation reduces the risk of a mismatched or incompatible component arriving separately. Cable routing between this module and the T20CU-J supply follows the same principle as linear track wiring — keep the run as direct as practical within the ceiling void to minimise unnecessary cable length while still reaching the chosen supply position. The compact size of this module means it adds negligible bulk to the ceiling void at the ring's connection point, an important consideration in installations where void depth is already a constraint. Confirm wire count against the ring's planned control type before ordering to avoid a mismatch at the wiring stage.
