Connecting a PIR light

Post by Argyll » Sat May 12, 2018 4:00 pm

I need to connect a PIR light to the rear of my house to shine on to my back garden. Can I take the feed from a socket using 1.5mm T&E or does it need to be 2.5mm T&E?

You have to use the same size cable that is already there. (2.5) This is because if there is a fault the weakest link fails first, which would be 1.5mm cable (if you used it)

How ever, what you should do, is to fit a 2.5mm cable feeding a fused connection unit, then you can use 1.5mm cable to the light. (you could also use 1mm cable)

If you get one like Image since it has an inbuilt switch it will make life easier.

I would also suggest two lights might be better, as one light is often mounted high up, which then lights up next door, the garden either side..........

Fret not, a forum is a collection of opinions. Above, are mine.

Which is correct? Metre or Meter? Click the link to find out more.

Working on anything electrical? have you got a multi meter? why not? Would you hit a nail with a shoe?
