I am putting in a new switchfuse (Wylex 110M
where the old CU was and putting in a new CU in a different location.
At present the incoming and bonding earths that were in the old CU I intend
to connect to the earth block in the switchfuse and to put in a new earth
cable between the switchfuse and the CU. Is this acceptable, or must the
bonding come into the CU?
The distance between the switchfuse and the new CU is about 5m - I intend to
use 25mm for the L and N tails (which will be clipped across the attic of
the garage roof - no insulation etc) and 16mm for the earth - any problems
The supply has the earth tied to neutral (TN-C-S, I believe).
