Question about T&E and spotlights in my new build house.

[thedanburgess]

Hi,

So I've just started to install some spotlights in a room in my house, and I always thought to use 1.5mm T&E so I've wired them all up and I've come to connect the main line in and noticed that it is 1.0 T&E. Am I okay to link the main line to my daisy chained spots on 1.5.


Some more information, the main line comes into the light switch and then out of the light switch to the next room, and then 1.0mm T&E to the existing light. As far as I can tell this is a radial circuit, the house was built last year if that helps.

Here's my poor attempt at a diagram.

Yes. Its fine.
Not really much in it.

1.0mm is fine in a house where theres no heavy loads on lighting.. All LED fittings.. be lucky if theres even 1A being used.

1.5 was common years ago when there was a couple of 500W halogen floodlights tagged on the circuit somewhere for outside lights
