The current transformer is supplied with a 1000 turn secondary only, for the primary I used 1 turn of 1.5mm plus 9 turns of 1.25mm flex which was about the maximum that the aperture in the core would comfortably take (see below).
The meter was built into an ABS Verobox 180x110x56.5. A Crabtree GB6:4304/D socket was fitted with a 16mm back-box behind the ABS to give a mounting surface for the C.T.
