I want to change the lighting under my kitchen units to mini fluoresent tubes (low enery 10w slimline ones) in the instructions it says they should be fitted to a plug with a 3a fuse or into a fused switch, the 3 existing lights are wired into the mains lighting circuit via a junction box. Can these be wired staight to the mains in the same way, if not is there a way of wiring them to the existing lighting circuit and using the existing switches?
fluorescent lights do need fusing but there is no reason why you should not feed the fusing unit from the main lights.
1) You need to wire to lamp not switch as there are no neutrals in the switch.
2) It will come under Part P look at links in Projects section.
So I would swap junction box for a fused spur unit.
Thanks for the reply, I thought fused sockets were to be used on a ring main or for a spur off a ring main, so its doesnt matter that the powers coming from a lighting circuit, I can keep the existing loop-in system and use a fused socket to connect wire to the fluorecent tube wire to the lighting circuit?
I have not mentioned a socket. Looking as Screwfix as an example 29775 MK 13A DP FCU is just a fuse holder and 13479 MK 13A DP Sw FCU also has a switch. Many fluorescent lamps have the fuse build into the lamp. The main thing is to follow manufactures instructions if it says fuse to 3 amp then fuse to 3 amp. I think that the 6 amp which most lighting circuits are limited to is most likely enough but I canâ€™t really tell you that is enough in case there is something which I am unaware of. The rules which we follow are contained in a big red book and to tell you all the rules would take a lot longer than I can spend on here. You would not connect a normal 13 amp socket to a lighting circuit although there are special sockets and plugs designed for lights. I do not like DIY but neither do I like Part P which rather than making things safer has resulted in forcing things underground but there is good reason for making kitchens a special location and before continuing you need to do a risk assessment is the risk to your family worth the money saved?

When you say Part P Projects section, do you mean e actual Part P of the Building Regs or is this content of a Part P course? Thanks Boab
I was referring to building regulations there is no Part P qualification. Electricians can pay an annual fee to self certificate their work and become a member of a "Competent Persons Scheme" which means they don't have to inform the LABC before starting or pay their high fees which seem to start at £100+.
As a result any work less than £200 which is notifiable is not really worth doing as DIY.
