Does a external flood light need to be on an RCD ?

Does a external flood light need to be on an RCD,

i was going to spur off a socket in the bedroom, if the fuse board doesnt have any rcd, should an rcd fuse spur be used? or can a normal switch spur be used?



Thanks,

No but the cable does.

 

[lee2lee]

what do you mean?

thanks

Fixed equipment outdoors does not require additional protection by an RCD.

If the cable is concealed less than 50mm from the surface it must be RCD protected. You could run it surface in trunking to get over that requirement and drill straight thru the wall from the spur to the light fitting. This may be what you intended I may have the wrong picture in my head

only if buried less than 2" blah,blah. passing through a wall doesn't count.

Whether the cable is underground or visible an rcd is not required.

Yeah if its on its own dedicated circuit and any of the cable internally is chased in less than 50mm from the surface and not protected by steel etc...... then I'd say def an RCD job. I'm presuming outside any cable run will be in conduit. If its all surface mounted then no need for RCD but wouldn't do any harm at all to put one in.

Would it make more sense to use an RCD Spur so that if water gets in and starts causing nuisance tripping it's blatantly obvious where the fault lies rather than have the upstairs ring keep tripping? I'm just wondering because not every spark will automatically presume that the outside light has been fed from a spur on the upstairs ring?

i've done a few spurred off a bedroom socket, using a D/P FCU, so in the event of a fault, it can be isolated. then drilled direct from back of FCU to outside. ( when i've been lucky enough to find a socket on the outside wall, no need to get floors up ). only problem with RCD FCU is if the circuit is already RCD protected, no discrimination.

Very valid points indeed, my concern was only the fact that if there was a fault causing nuisance tripping a spark may not identify the problem straight away but then I guess an experienced spark would already have clocked the outside light and looked for where it is supplied from?

As you mention though, was identified it is easily dealt with

No floor boards up, we like that bit

Discrimination, we most certainly don't like that bit.

All noted, Thanks as always telectrix

Thanks,

For the cost of a RCD switched fuse outlet you might aswel use one
im sure any equipment or circuit running outside would benifit from one.

Holy thread resurrection batman!

Do tell us all how the outside light is going to benefit from having RCD protection?
