Lighting from ring main

[Fordy81]

I want to connect 3 sets of vanity lights around a mirror and the easiest way would be to spur off a ring main socket.

I was planning on putting a 3 or 5 amp switched FCU next to a socket, joining the 2 with 2.5T&E. Then 1.5T&E up to a central back box behind the mirror. Then 3 cables coming in from the lighting units and joining the 4 lives together, the 4 neutrals together, and the 4 earths together with some Wago connectors which would be behind a blanking plate.

The lights are double insulated so don't require an earth to the lights so should the earths just be connected to the metal back box?

Is there anything I'm missing?

Sounds OK, but why a FCU? Why not simply add another 13amp socket behind the unit, then plug the lights in? It wouldn't look that cleaver, but I suppose you could take the three flexes into the 12amp plug, if the three are part of the same unit..

I don't have the depth behind the mirror for a plug unfortunately

Not good practice to fit the three flexes into the plug (if that’s how I read it) would be better to split the flex at a junction box and have one flex at the plug

What room is this in ?

You only need 1.0 mm cable to the central point not 1.5.

0.75mm even.
