No earth in circuit.

[Dvid80]

Hi all, I recently done a job fitting a new cu. All circuits were fine except the kitchen lighting. It was only two core and had no earth.
The client does not want any mess making in his new kitchen.
Would I be right in informing the client of the danger and putting it in his installation certificate.
Is it then up to him whether he has the work done or not?
Would I be doing the right thing in the eyes of the niceic inspector? As I plan this to be one of my two jobs for inspection.
Thanks for any advice.
Oh also, is it ok to run two small lighting circuits from the same 6a mcb?

Is the Kitchen Lighting Class 1 or Class 2

Here's a link to the ESC best practice guides...

there is one on CU changes with lighting having no earth

If all the light fittings and switches are double insulated then there's no big deal.

Nothing wrong with two branches of the same circuit leaving a single MCB.

Good advice and links Nozspark.....

I was about to lead the O.P through the same ESC advice on a step by step basis ,but your links should put him on the right road.

The client does not want any mess making in his new kitchen.

Presumably it's not good customer relations to say to him "You complete tw@ - why on earth did it not occur to you to sort out things buried in walls and concealed above ceilings before you decorated them?".

Correct, in fact it is frowned upon.

You should not reconnect this circuit if it has Class 1 fittings on it regardless of a notice being issued or not. It should have the fitting(s) replaced for Class 2 and also any metal plate screws swapped for nylon if the box lugs are metallic.

As stated, you cannot have class 1 equipment on a class 2 circuit, this is pretty much common sense, should the metal casing become live then there is no return path for the fault current!

If The customer does not agree to the installation of a cpc then......

A Risk assesment is required.

1. Are there any other Metallic parts which can introduce an Earth potential simultaneously accessible with this light fitting ?
2. Is the Insulation Resistance between L/N and the M.E.T. at least 1 Megohm ?
3. Is the Insulation Resistance between L/N and the mettallic parts of the Class 1. Light at least 1 Megohm ?

1. If yes then Class 2 light is a must or dont connect the light fitting.
2. If No Then same as above.
3 If No then same as above

...if the tests permit the connection of the Class 1 light then a notice has to be installedm at the c.u warning of the lack of cpc at this circuit and instructing that any class 2 light fittings be NOT replaced with Class 1 type.

 

[spark1]

Oh yes and ensure that on the E.I.C that you state the C.U has been installed in line with the ESC Guide

Does NICEIC's ESC Guide have official regulatory status, i.e. following it means that you don't have to comply with BS 7671 any more?
