Wiring outside lights

[inamess]

Please need some help! Want to wire four outside bulkhead lights down the side of my house, controlled by two PIRs at either end of the building so that whichever end you approach from all four lights will come on. I.E each PIR should be able to turn on all lights. Power will come direct from CU.

Three core and earth.

connect it into all lights and both pirs

each light will have a neutral and switch live, each pir will have live neutral and switch live

earth not counted

but since you cant run a 3 core and earth outside you will need to give it mechanical protection (and sunlightprotection) black pvc conduit will work

Do you mean take three core from power supply to PIR then on to each light in turn and on to other PIR then back to power supply forming a complete loop???

 

[breezer]

no loop, but yes

By mechanical protection do you mean RCBO in CU or am I on the wrong track.

may i suggest you read my post again (i anticipated this question)
