Is it possible to gland two 10mm2 SWA (3 core) cables directly to a metal garage consumer unit, something like this:

If not, and I used an adaptable box directly beneath the unit, could I gland it in the box and then take the tails through into such a unit (would there be room for two lots of 10mm2 three core cable)? Or would I be better off joining them both to a single 10mm2 T&E cable in the box and take that to the CU?
If using a metal adaptable box, should I use a cheaper plastic CU? Alternatively should I just use a bigger metal CU (what size would be big enough to gland both SWA)?
(the first cable will be the supply in and the second will be the supply out to another shed)
