Wiring a shed/treehouse with led lights in ceiling with splitters

[barnsley7]

I'm wiring the ceiling in my shed/treehouse with led lights.
I'm wondering if I can join 4 led lights up in a circuit by just using splitters. They are all the same; 1 input and 2 outputs.

So after the first AC input I want to continue the AC power by splitting off and feeding each light in the ring of 4. So each splitter will have 1 AC in and coming out there will be 1 pair of wires to a light and the other pair continuing to feed the next splitter.

Does that sound ok?

I'll wrap with electrical tape when finished. They're only low power lights, 3w 300mA , each with a drop down transformer to DC.

Because that's the number one strategy recommended by BS7671 for making a safe electrical installation

It would be far safer to have your transformer indoors and have only low voltage (SELV) cables, connectors and devices in the children's deathtrap.

other places seam too ! lol

That’s US standards with 110voltage .

 

[AndyPRK]

outlet doesn't look American.
more like Aus or China

At the end they fit a Chinese (220V) faceplate.

For mains wiring, all connections must be inside an enclosure with no internal conductors on show (ie the outer cable sheath must fully enter the enclosure). So, those mickey mouse chinese connectors must be inside a box. You cannot wrap them in that sticky tape (that comes off after a season of frosts and sunshine).
I worry abouit the picture of the LED driver that seems to show the inners of a mains cable. That driver will also need to go in a box.
Oh yes, and as well as live and neutral, you must also provide a earth conductor all the way from an earth source, at each light through to the last one. Even if the downlights do not need an earth.

Re our castaway's suggestion

True that it might be safer, but there may be issues as extra low voltage lamps need a much higher current, so the lights may be rather dim if the hideaway is any distance from the "indoors".
Probably @JohnD has been on his island for so long that he has forgotten that mains voltage (230volts) is defined as "low voltage"

JohnD is wise enough to know what the general population think "low voltage" means

And educated enough to add (SELV) to placate the others


He has enough information to confidently predict which group the OP is in.

Please don't. A plastic enclosure such as a Wagobox is far better than tape.

Thanks for the replies.
* I've just ordered some junctions boxes to house the connectors.
* The structure is well built, so not going to rot easy. It's 6ft off the ground, so not much splashback from the ground.
* It has a EPDM roof and I intend to inspect it against the weather all the time and keep it waterproof.
* It has tongue and groove loglap cladding and will be treated when necessary.
* it's 40m from the house and will have SWA cable connected by an electrician who will also connect the light switch to the lights.

...the lights are not earthed. The lights didn't come with an earth so I thought earth wouldn't be needed.
Also, when I asked about the lights, someone advised that connecting them with 2 core wire would be ok.

This driver will attempt to force 300mA through whatever is connected to it's output. It will alter the voltage on it's output to achived that 300mA current with a rated maximum of 15 Volts

5 white LEDs connected in series will require more than than 15 Volts ( typically a white LED require 3.2 Volts )

This driver may be rated at 3-15 Volts when in fact it can produce the 16 Volts or more needed to drive 300 mA through 5 LEDs and the resistance of the cable carrying the 300 mA

thanks but i'm not sure what that means?
i'm keeping one back as a spare so only connected 4 of these lights.
