Hi all,
I’m looking for some advice regarding the best way to wire a 54W PIR floodlight to my garage. I have used the floodlights pre installed 1m of cable to enter the garage and added 1.0mm T&E cable via a choc bloc inside an in-line connector box.
The garage is powered from a radial coming from the house fuse box via armoured cable into a SFCU.
From the SFCU is a double socket powered from the supply side and a ceiling light from the load. This was all completed by the builders and is shown below;
I’m looking to power from the floodlight from the radial. I would like the floodlight to be permanently live so it can operate from by its PIR. It would be nice to override the PIR when required to have it permanently on but I don’t think that’s possible? I have looked into options and unless I’m incorrect they are;
1. From the SFCU add a 2 gang switch. Wire the floodlight into one switch which would be left switched on permanently (still allowing isolation if needed) and the existing ceiling light into the other switch.
2. Spur from the supply side of the SFCU into a another SFCU/Unswitched FCU with 3a fuse. Wire the 1.0mm T&E from the floodlight into the load of the new SFCU. As below
3. Replace everything with a grid switch with 3 modules; 3a fuse - switch - switch. This would probably look neatest but I’m not entirely sure how to wire a grid system. Would it be line into the fuse then loop into switch 1 then switch 2? Neutrals into terminal block and earth terminal on the back box?
I’m happy enough to do this myself, I’d just like to see which option appears best and make sure everything is correct. I have considered sticking on a plug with a 3a fuse and plugging it into a socket but would rather keep them free for appliances.
Thanks in advance.
