Thanks for clarification of the wiring. Apologies that I have ony just seen your post. Although the wiring is certainly more conventional than that of the assumption I made earlier, my earlier wiring advice remains valid, as confirmed by Nigel.

If, however, you wish to utilise a master socket capacitor, connect the A leg of the line (usually white) to L1 and the ring wire (usually blue) to R (or T, as they're strapped together).
