Why does it need an RCD?

Good question, answers on a postcard please.

Because that's all DI's install, it's their way of making everything "safe" without knowing why or what they are doing.

I'll agree with Dillb now I've corrected his post.

Regulation 411.4.2
Each exposed conductive part of the installation shall be connected by a protective conductor to the main earthing of the installation, which shall be connected to the earthed point of the power supply system.

Regulation 522.6.6 (iii)

The cable must be enclosed in earthed trunking or ducting
as specified in 522.6.6.(iii)

If the above where done then yes it would not require an RCD

It doesn't need an RCD as it is now, it just needs fixing!

An RCD does not negate the need for steel conduit to be earthed or for it to be properly constructed.

An RCD is not a magical device that excuses all bad workmanship!

 

[davesparks]

Ok I can't even find 522.6.6 in my regs book, the nearest thing is 522.6.100 onwards which variously contain those words. But they all specifically relate to concealed cables, not surface conduit work.

Wel maybe you would like to read this: http://www.google.co.uk/url?sa=t&rc...zbQHBXjklYkANBA&bvm=bv.76477589,d.ZGU&cad=rja

What's occurring in the 2nd picture where the tube is cut off?
Where are the cables going?

522.6.6.200 says it should be coloured in brick pattern paint. Fail!

That link is irrelevant as it is only concerned with buried cables, not surface installations.


You are probably right that it should be earthed, but an RCD is not an alternative so fitting one will achieve nothing, so again why do you think it should have an RCD fitted?

I say probably as it is obviously T&E inside the conduit, which is a wiring system in its own right, so it is possible that there could be some debate from some quarters as to whether it needs earthing or bonding or neither.

Also as T&E is suitable for use without additional mechanical protection there is no requirement for the conduit to pass through the doorframe.

Ignoring whether an RCD is required or not;

How has the O.P established there is no RCD fitted, when it's not in His/Her premises?

 

[lee0069]

Yes but as the conduit is insecure and the cable could be pulled out if the light fitting , and the line condutor could be toching the unearthed conduit .Am i the only one who can see some one getting an electric shock?

And yes i agree if the conduit was secure and continious then there is no need for an RCD , but the conduit has never been earthed or mechanicly or electricy continious.
