Supply to lights

[doodarr]

Hello gents,

Has anyone encountered the supply 'loop' to a lighting circuit being installed in the switch? Rose has 1 T&E 1.5mm and switch has about 4 red wires and 4 black wires (in two separate blocks). I've never seen it before but the switch is wired as a regular rose would be and the rose is wired like a switch. ?!?!?!
Not a customer just a friend’s house I looked at when he told me he wired the me light fitting with only 3 wires I got suspicious and had a look.



Thanks

This has been discussed on this very forum in some depth mate. The general concensus was that it's an acceptable wiring method although personally it's a no no but my ---- retentiveness is well known

strange....theres a lot in here that dont like neutrals at switches...but the way i see it its in an enclosure...and all joints are accessable....not often the case with joint boxes....

perfectly acceptable way to wire it. saves having too many cables in light rose, but you do tend to get switch boxes a bit crammed if you've got , say , a 3 gang switch.

See it loads of times, if the customer has fancy lights. Makes it easier to terminate one cable in the light fitting.

sometimes it done for practical reasons, for example if you have a house with lots of wall lights then you don't want to have 3 or 4 cables to deal with behind the fitting. Nothing technically wrong with the method, just most sparks wire to the rose as its easiest to install and fault find.

The older gen' on here would generally swing to it been a no-no due to there teachings and for a period was frowned on, but practice and teachings changed and times moved on, i did used to consider it bad practice while i was using the 15th regs but i was converted many yrs ago as common sense in the industry prevailed, although its standard practice for some councils to request this method is employed on any of their housings.
Agree with the general thought on is in that it is acceptable and no longer falling into the realm of bad practice.

I did one the other day that was 4 + 2G dimmer in a 6G plate, with three different loops and 3x 2-ways. Now THAT was a busy box!!!

They don't come much older that me so I've seen loads of fashions change. The system you are talking about was used a lot when you had flat roofs of no loft acess to contend with, only one cable to fish over the ceiling. I also remember a 7" square rubber joint box, one in the roof and one under the floor on the landing. All switches and light came back to the same box. Saved a lot of cable in small houses but you nearly had to jump up and down on the JB to get the lid on. Happy days

Hi guy's,

Walk the dog and come back to all the answers lol. I'm fairly new to the game and hadn't seen it. It's neat and well done but I was unsure about it as I always am. The reason I assume it was done is that it's a flat with a concrete roof as said easier for access and space.
Thank you for all your help once again gents. )
