one single or double socket per spur, taken direct from a socket or using a joint box. Or from origin of circuit ie at con.unit!
Optionally if you go to a fused connection unit (fused spur) first then no limit to number of outlets on a spur.Usefull if feeding say a conservatory, also can be run in 1.5mm fron FCU if run is short
I can hear the keyboards clattering already so will mention appendix 15 in red book as source.
Hi best way would be to fit an unswitched FCU by original socket, divert out going cable[s] thro' it with short link from socket to FCU, then you could if wanted loop on from single sockets for say under cupboard lights ect.
we must of course point out that any wiring in a kitchen is notifiable to Bldg Control, see 'projects Part-P'
