External PIR light

[DavidJT]

Just bought a new PIR light for the porch. The old one (which was there when i bought the house) was connected directly to the lighting in the mains box!

I installed my new light from the existing cable to a switched FCU and then to the light but the light doesn't work!

What am i doing wrong?

//www.diynot.com/wiki/electrics:lighting:single_way_lighting scroll down to the diagram for your light. If your pir needs a permanent live & a switched live, take it from the fcu using 3-core & earth cable instead of 2 core & earth

And what would be wrong with that, then?
