I was wondering if anyone has experience of wiring an outside PIR light which is wired to an internal fused switch.
I’ve taken the old light off and the wiring coming in from the wall looks as per the image attached
The wiring for the new light looks as per the second image
The wiring on the new light appears to have only 3 connections where as the the old connection has what appears to be two live connections and 4 wires in total (I’m assuming one of these comes from the switch). How should I connect the 4 incoming wires to the new lamp?
Any suggestions or comments would be gratefully received
Some PIR's can be shorted out, so can be over ridden, others can't. Top clearly line supply. Next parking place for earth wire. (Your green/yellow) Next neutral. (Your grey with blue sleeve) Bottom switched supply, with brown and red wire already fitted, so you have black with brown sleeve and a brown which likely go to top and bottom, but no idea which goes where, as nothing in pictures show which is switched line (bottom) and permanent line (top) of the black and brown wires.
Personally I would connect and test, and if did not work reverse the brown and black wires. But it could damage the PIR no way of knowing.
All makes sense apart from the switched live (Black with brown sleeve). As you say the 4th connection on the block has a brown going into the top coming from the main cable going into the lamp and a red from the bottom going to the PIR unit. Are you saying my switched live should share a connection with either the red or the brown but you can’t say which? On the original connection block the black with brown sleeve is marked * and the brown is marked live Thanks again for your help on this
Connect the earth to the earth you mentioned. Connect the grey (with blue sleeving) to the neutral (The one with 2 blue wires) Connect the brown to the live (First terminal, the one that already has a brown) The black (with brown sleeving) must go in its OWN connector or a wago. It must NOT be connected to the light, and insulation tape wrapped round will not be suitable.
So the switched live will not be connected to anything. How will this affect the function of the lamp - does this mean that the internal switch in the hall will no longer turn the unit on? The lamp will only come on through the PIR sensing movement?
