Fitting P.I.R light outside my front door

[arethusa100]

Hi. First time on the site.
I want to fit an outside P.I.R light to my house. If I fit the light off of a junction box spliced into my light circuit (protected by RCD) should I fit a fused spur on the circuit as well or will the RCD at the consumer unit be sufficient protection ?

Unless the manufacturers instructions call for the use of a FCU then the light will be fine fed straight off of the lighting circuit.

Apart from the fact that you won't be able to turn it off.

you will also beable to safely isolate it without having to turn off all the other lights.
