No but shorter the better less 16mm.

I would say choose the wettest place you can, even if it's a bit further away.

I think you could go down to 4mm (not mechanically protected) on a TT ....IIRC

Not that I would...

The important points are keeping it accessible for inspection and testing.

and if it is in an obscure place then make sure there is a clear label at the CU to identify its location.

Basically put it where you can dig a suitable inspection pit cover

and run the earth wire where it is least likely to get damaged.

and is meets your max Ra value

and the customer is happy with.

i.e. the key reg 134.1.1

Good workmanship & Proper materials etc..
