Class II

[cliffed]

Replacing lights in office , where there is no earth continuity on the existing circuit.
The new lights are Class II & require no earth.
The client refused rewire of the area, the cabling is T&E but no earth connection..is this legally correct.

When you say no connection does this mean there are cpcs but there is no continuity through them.

This analogy may help: even if you are plugging class 2 appliances into a radial sockets circuit the circuit still requires a cpc to protect the cables.
Same for lighting circuits - even if the cpc isn’t connected to each luminaire it needs to be connected to the next length of cable and so on.

A 'short' 2 core flex via a connector may be permitted for the light, but the circuit wiring should incorporate a cpc as stated by others.

Yes no continuity on the cpc

Totally agree… it would be easier to install new circuit to the area.

Yes no continuity on the cpc

That needs sorting before any other work is done.

 

[timhoward]

Is it grid ceiling? Can you get a Zs at any of them? I tend to find the one that works and start there using quickwire flex connectors

It’s a complete mess… those above have insisted on fitting these lights without even the thought of finding the fault..

Has anyone made an attempt to resolve it. Are the light switches earthed.

No they haven the switches are normal plastic

 

[westward10]

So has anyone tried to resolve it.

No

Their remit was fit Class II fittings

Still doesn't get round the discontinuous CPC, I'd walk away of that's their attitude.
