2.5 T&E is not rated to 32A, nor does it need to be on a 32A MCBed ring.


But it is rated at up to 27A, so using a connector rated at only 24A
makes it the weak link, after all we don't know how far round the ring
this junction box is ...


Only if clipped in free air.

In conduit, under insulation etc it is rather less;

But should be =20A for the installation method and conditions.


433.1.103 in the green book give the 20A figure.
