i cant ask the brother, he jumped on a plane for a holiday so im back for advice :)
ive almost done the downstairs lighting circuit but got reminded that we are having wall lights in the front room, im wondering how to go about wiring them up to meet 17th edition as i was told i cant have any concealed junction box's in the floor space upstairs ?
due to this i am opting for ceiling roses and wonder how to go about adding the wall lights ?
I would use a deep switch box and use that as a junction box.
All the wiring regulations take some interpretation and what it says is where screw terminals are used there must be access.
It does not say what it considers as access some people consider a bit of screwed down floor board with wiring underneath written on it is access others consider since carpets will cover this it is not access.
As a result what one inspector will pass another will fail so if possible always ask the person inspecting.
Junction boxes with spring connectors are permitted as they have no screws to work lose.
For my wall lights I used conduit boxes behind them as screws in lamps matched conduit boxes leaving loads of room for connections if required also easy to replace with klick type ceiling rose again screw hole spacings match.
Common sense has to be used as well as the regulation book.
just a suggestion you could take a twin and earth down from the centre light out of the ceiling rose down to your light switch and then a twin and earth from the light switch to your wall light and then from the first wall light to your second wall light so on and so forth to however many wall lights you are fitting. At the light switch in the back box you put the neutrals together in a connector block (blue wires)and tape it up with insulation tape and then put the brown wires into the switch and the earth wires into the earth connection on the back box.This is an accepted code of practice and complies with the regulations and limits the cables at the wall lights
