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

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 ...


Box of 222-412 ordered from Amazon.


Note that 222-412 connectors are derated from 32A down to 20A when used in a maintenance-free enclosure (see
