Singles are always really easy to visualise. Where it becomes confusing for me with lighting is when you have to figure out which run needs 3 core and which needs twin. If only we could always wire in conduit like they do in Europe.
Just out of curiosity, is there a rule that would prevent putting a wago in the conduit Tee box for the line conection, so you don't need to run the permenant line back up from the switch common to get to the next switch?
I've always used the third terminal on the small-base batten lampholder as the line loop-in terminal, which suits the classic application in steel conduit. Some brands of batten lampholder have the third terminal shrouded and marked "LOOP", but I do know that the Chinese "PMS" brand (from typical non-trade sales outlets) have a non-shrouded third terminal marked with an earth symbol. That terminal does not connect to the bayonet collar - but if it did, that could be a serious concern with the apparent similarity of the product. In plastic conduit installs I used to get the little brass earth terminals to go in the boxes (there's always a place in the mouldings for fitting them) but generally use a Wago terminal instead these days.
Not a sparky but interested to know what is the advantage of this over traditional ceiling roses type installation? Seems you have to run an extended amount of cable to the switch rather than back to the 1st lamp? I guess there must be something wrong with using something like a maintenance free box and wago’s? It would be nice if it was compulsory to leave wiring diagrams in domestic properties showing where the cabling goes. Fan of the channel and Efixx as well.
Hi David - in singles you can take the cables exactly where they are needed, so the permanent line isn’t needed at the lighting point so we take it to the switch and from the switch the switching line goes to the lighting point. Massive thanks for the support across both channels 👍🏻 Gaz
“Loop in” always confuses me. Surely it doesn’t mean anything specific. 3 plate method - “loop in” to ceiling rose 2 plate method - “loop in” to switch. Loop in by itself doesn’t mean anything to me
