Always go for the better option with cable sizes. I would personally never use 16mm whatever the incomer fuse. Even if you know it's 60A or 80A, pretend it's 100A and put in 25mm2 tails ( double insulated ). The 17th Ed. recommends that anyway whatever.

quite right haj, exact wording is

"polarity should be indicated by the colour of the insulation and the minimum cable size should be 25mm2"

theres 2 shoulds in that statement. would your mate ignore the first should the sameas he would the second should

25mm it is then

Do you get leb in to pull fuse or are we aloud to disconnect from there meter

I always use 25mm tails, just remember to upgrade the bonding cables to suit.
The meter tail size is dependant on the cutout fuse rating as far as i `am aware.

Just do it.Pull the fuse.Who says there was a seal on the cut out anyway
