Fitting a PIR Floodlight

adam1984 · May 25, 2012

Afternoon all.

I want to fit a PIR floodlight.

currently have a standard light off the lighting circuit with standard light switch.

Can I use the whats already there of do the PIR's require a power circuit (L,N,CPC). If so I will have to run a Fused spur off a socket.

I will surface mount the cabling as no RCD protection in place.

Don't hold me to it but does your sockets have RCD protection via the cu as if your going from a fused spur that should be fine. As anything out side your property needs to be RCD protected.

There is no requirement for external lighting to be RCD protected. Socket outlets used outdoors yes, lighting no. As with internal lighting circuits they only require RCD protection if they include buried cables <50mm, without mechanical protection, or if they are supplying bathroom circuits.

Yes, I would imagine the existing light fitting has L N & CPC, as such the new PIR fitting should work as a straight swap. however you would have to leave the internal switch 'ON' for it to work automatically.

+1 just connect it.

It's handy to have the inside switch. As Doc says, it will need to be left on all the time for the light to work.

But the switch gives you a means to turn it off whenever you need to change the lamp, and also most (but not all) PIR lights have an "override" mode whereby if you want the light to stay on, you just flick the switch off then straight back on again and the light will turn on permanently.
