RCD Protection

[carl9254]

Goin to quote a job tonight, went round yesterday for a quick look.

Basically there redecorating there master bedroom, there is only 1 double socket next to the door, they want 3 more around the room. Its an old use box with no rcd's and dont want to upgrade, will i be ok putting the new cables in steel earthed trunking?? Or shall i only do it if they upgrade??

 

[Amp David]

If they won't pay for the upgrade then the only way is to protect the cable as you say, or make sure its 50mm below the finised surface, which is probably impossible to do.

Chase out and wire it in SWA or you could surface mount

Could use a fused spur unit with a built in rcd HERE and mini trunking.

Would i have to do both?? Or you sayin that for extra safety??

So my options are;
Wire in 2.5mm pvc and use steel trunking.
Wire in SWA with NO trunking
Or switch fused spur 2.5mm pvc and no trunking??

Am i right??

 

[pushrod]

you could surface mount, but would look much better in mini trunking IMO

Much easier and less hassle option compared to chasing out.

Use conduit and not trunking making sure its earthed properly
Yes, but ensure the armour is earthed properly
Yes

 

[carl9254]

They defo dont want surface mounted stuff, so am i right in saying steel trunking means no RCD??

DOH.

Meant putting it in surface trunking.

Yes

Why conduit and not trunking?? Will make sure it is earth properly

Wot does everyone reckon best option??

 

[pushrod]

yup, the little white plastic stuff cheap, quick and neat.

If they dont want surface mounted, then its going to be easier to sink steel conduit into a wall than trunking.

After suggesting all this, I would use the RCD spur method. Quick and easy

 

[carl9254]

Ok how much are they and where from??

 

[ryanryan]

i dont think they would want a SWA around the bedroom

 

[Amp David]

Who says you have to always surface mount SWA?

 

[pushrod]

Ok thats the plan then, steel conduit, 2.5mm pvc and no RCD, thanks everyone

Your cable won't need rcd protection but i think the new sockets will.

wow that was a quick edit carl LOL

Ok how much are they and where from??

screwfix HERE £23.63

do i get a thankyou

 

[carl9254]

Mighty quick ha. Wot you mean about sockets?? I thought if cable is in conduit then no RCD needed?? Looks like il do the RCD spur though. A big thanks, and a cheers

The cable is excluded from 50mm rule if in steel conduit but the new sockets, i am fairly certain, still require rcd protection. eg if you were running cable for lighting in conduit you wouldn't need rcd for the circuit (but all new sockets do). So it's either upgrade the CU, RCD protect the ring or the fused rcd unit as the only options.

(the button is what i crave)

 

[sonobit]

I had a similar problem a while ago, and alot of the senior members on here were basically saying that i was responsible for the whole circuit i was working on, so it meant RCD the whole circuit at the board. Which i couldnt do either so i just ran a RCD fused spur instead...! easy option and you are protecting your own work.

If you can put a RCBO on the circuit at the board. You WILL need RCD protection on the sockets you install regardless!

 

[Risteard]

Socket outlets in a domestic premises require RCD protection.

Ok thanks everyone just got back from quoting job. They have picked black nickel sockets etc very nice, trouble is my only supplier electric centre dont do em also this rcd switch fused spur is white, is there any others out there to match the black nickel??

Also when installing new sockets do i have to put them between 450mm and 1200mm or can i do them to match other sockets in the house??
