meter tails

[panny300]

what size meter tails need to be used for a separate shower cu,it will have 10mm cable to the shower.
can they be 10mm or do they have to be the same size as the original tails,or do all the tails have to be uprated to 25mm. thanks

25mm should be used.

thanks steve,do you mean just to the new shower cu or to the original as well,
or 25mm from meter to henley,then split 25mm to new shower and leave the original tails to original cu.
the original cu is the old wylex rewireable push in fuses,would this take 25mm?

If you're on a mobile then at a push you can use txt spk. Although with predictive text there's no excuse now really.

However, it would be appreciated here if you use full spellings.

I think he's saying you would struggle to get 25mm² tails into a shower consumer unit.

Why?
