Another FCU question.

Hi,



I'm intending to power some under kitchen unit linklights from an FCU (3amp or less) mounted on the kitchen ring main. My plan is to take a



1mm2 T&E from the FCU Lout to a wall mounted lightswitch to provide a switched L (at the FCU), connecting the linklight to the swL and Nout of the FCU. My question is does the FCU need to be switched (for isolation)? Fixed lighting doesn't normally have DP isolation but an appliance hard wired to an FCU I think would require DP switching.

Secondly can I assume there would be no problem taking an unfused spur (to a second FCU) from an FCU on a ring main, providing that the terminals will actually take 3x 2.5mm2 cables (I guess some/all? will).



Thanks



Jim

No, only fixed heating or motor appliances. Lights don't.

It might be advisable to label inside the lightswitch that this circuit is fed from a power circuit via a FCU and not the lighting circuit.

If the FCU is *on* the ring main, OK, it is just the same as if it were a socket.
