Inside a 2-Plate Ceiling Rose
A 2-plate ceiling rose has two groups of terminals: one for the live side and one for the neutral side. The supply mains does not loop through.
Terminal Layout
What Goes Where
Plate 1 (live):
- Brown (L) from the feed cable
- Brown from the switch cable (switch live going out)
- Blue, sleeved brown, from the switch cable (switch return coming back)
- Brown from pendant flex (receives live only when switch is on)
Plate 2 (neutral):
- Blue (N) from the feed cable
- Blue from pendant flex
Difference From 3-Plate
In a 2-plate rose, the live supply and switch live share the same terminal plate. You must be careful to identify which is which — all three brown/sleeved conductors at Plate 1 are live at different times.
Earth
Earth conductors from all cables connect to the rose earthing terminal (or a separate earth block if the rose doesn't have one). The pendant earth goes to the fitting.
