The circuit cable is larger. It has 3 coiled earth wires for a start.
I spurred off with a 30amp junction box using 2.5mm.
Why should the cable all be the same size?

It sounds like you've got old cable called 7/0.29. There will be 7 strands
of 0.29" twisted together for the live and neutral and 3 of 0.29" for the
earth. That is the old standard ring main cable replaced by single strand
2.5mm TW&E about 40 years ago when such things went metric. If it has PVC
insulation it should still be fit for further service. If earlier it could
be rubber and likely to need replacing.
