Downlighting
Do they get wired up like a daisy chain?
Or another way?
Cheers all

Daisy Chain for the connection and fire rated spots if people live above.

If they are being switched by the same switch, then they’re connected in series.

Electrically in parallel yes. Otherwise removing a bulb would result in all the other leds going off. BUT, in practical terms Dick is right as in the loop-in system allows you to chain the fittings one after the other (in a series if you like). You can also fit them using a JB per fitting if the JB remains accessible but if you're doing a lot of leds that isn't a good choice. Don't make the mistake I did recently of buying cheap spots that didn't have enough space for a loop-in/loop-out. |

Sometimes it's terminology which cause the misunderstand HMV4U - neither of you are wrong but for the items to work electrically they need to be connected in parallel. As an example this quote below is used to try and make such an issues more understandable. "The term daisy chain may refer either to large scale devices connected in series, such as a series of power strips plugged into each other to form a single long line of strip of the items but the said items are wired in parallel." |

Note :- if you use spots which only allow for two wire connection (live and neutral connections) you must maintain the cables earths integrity or you could give yourself a nasty problem going forward if a cable got damaged in anyway.
Now in case the above didn't make sense here's a quote from another poster from another forum
"The point about the earth wire within a cable is that it is not just there for the benefit of earthing accessories and fittings. It is a circuit protective conductor (cpc). It has dual function. The primary reason for a cpc is to provide a continuous conductor for the passage of earth faults throughout the circuit, irrespective of what it is attached to, and hence ensure safety protective devices can operate. The cpc should never be broken at any point. People who cut cpcs off because they don't know how to deal with them or they are "in the way" are ignorant of this fact. A second reason is to "earth" accessories and fittingsthat need to be earthed. A third reason for a cpc not to be cut is for testing purposes. Cpcs are used as test paths to prove conductors are continuous and in live tests to measure maximum impedance is not exceeded. So you can see the importance of keeping earth wires intact. If a cpc is not needed on the accessory it should still be sleeved and terminated in to a connector block. The spark who is doing the test will not thank the idiot who has cut the cpc off."

He explains it well in this link: www.ultimatehandyman.co.uk/how-to/light-fitting/install-downlightsQuote from the link: "Downlights are wired in a radial circuit and so the feed wire goes to the first light in the circuit and then from the first to the second and then from the second to the third etc. When you get to the last light on the circuit the wire is terminated into the last light and so there will only be one wire at the last light fitting, as opposed to two at all the others."Here's a decent vid. |

I do normally like UltimateHandyman but I didn't like in that video how he put his bare hands over the tape and waggled it - could have used insulating pliers. Also is testing for live using a remote type device always safe? I dunno - I use an old fashioned analogue multimeter for that as the needle is very clear.
I've watched a lot of this guy. Bit of a nerd but knows his stuff and explains it very well I thought.
