Ceiling downlighters and rcd

[m4tty]

Hi,

I've wired up 6 downlighters in a landing and wanted your thoughts as to whether it needs to be rcd'd as all the wiring I've done has been above false ceiling and in loft. I think as I've worked on the circuit it will need to be rcd'd but was asking as I've done other work round there and it's got a split load With unprotected ways and one rcd with nearly everything on the rcd side and I'm running out of room so will have to go rcbo if you recon it definitley needs to be on rcd

thanks for any replies

Would depend on the length of cable down to the switch. No need to RCD if deeper than 50mm or suitably protected by mechanical means. Also the run from the CU to ceiling will be in wall? or trunking?

I think it may be in metal conduit on the landing switch drop but doubt the strappers will be more than 50mm deep. I'll get an rcbo in the morning. Thanks

Am i not right in saying that if the work matty has done doesn't require an RCD then it doesn't need one as the existing cables that are burried in the wall are not part of his minor works cert. I was under the impression that when you add onto circuits your own work has to be upto 17th edition, and not that you have to bring that circuit upto 17th edition?

Matty,

If all the cables that you have installed aren't <50mm (etc) or in a "special location" then they don't require RCD protection.

You could advise it, but not really insist!

 

[SPECIAL LOCATION]

Cables in ceilings do not require RCD protection...

Check out 522.6.4 & 522.6.5 page 100

Unless

1/ It is a circuit in a bathroom 701.411.3.3

2/ manufactures specifications stipulate otherwise. 134.1.1

3/ Its supplying sockets used by ordinary persons 411.3.3

4/ It liable to being pee'd on by Admins puppy!!!!!!!!!!

oops sorry GuinnessGuinnessGuinnessGuinnessGuinnessO)

Do NOT forget the reg 522.6.6 which includes RCD option is the CABLES IN WALLS bit!!

That should be:

3/ It's supplying sockets "intended for general use" by ordinary persons 411.3.3.

cant expect to include every last detail in the post,

I stand corrected.....

But did I get 4 right???????????????????????????

:Salute

 

[spinlondon]

Appologies, just trying to remind people that not all sockets require RCD protection.

Would depend on the length of cable down to the switch.

What's the length of the cable got to do with fitting an Rcd ?

I agree :Salute Unless there is a bath on that landing :run

 

[steptoe]

I fit ELV fans in bathrooms all the time with no RCD,

whats wrong with that.?

 

[spinlondon]

Doesn't comply with BS7671.
