Ohh God, this ones going to go on & on, no offence Ian & essex.

You really do not need to stay. Ian is highly competent and if I can learn then why not continue debating?

Stop your making me blush

Nothing wrong with a good healthy debate, as long as it stays friendly it's what the forums here for imo.

Haha

Would you use an OCPD for fault protection on a cable?

I had thought an MCB was an OCPD that was used for fault protection (via loop impedance) - so, yes I thought 543.6.1 applied.
Is it your view MCB do not provide fault protection?

Isn't it going off topic; the OP has asked several times the same question, our 'healthy' debate is not helping?

It was a simple question on how to connect a luminaire?

Which of you has the biggest van?

Clematis, can you stop derailing the thread please

Please. I don’t drive ‘a van’.

Certainly not in a domestic setting these days.

 

[Risteard]

the equipment may not need a cpc, but the cable to it does.

The cable doesn't require a cpc (otherwise singles or two core cables would be prohibited). The point in wiring (i.e. the accessory) does though to comply with BS7671:2018.

Because it is confusing to the O.P. and will give up and not return.
This just goes to show the mentality of same (not all) house bashers (new development homes) instead of parking the CPC in a terminal block, Wago etc. cut it off as it is the easiest and quickest option.

You must of had a Freudian slip then.

 

[Ray Pooley]

All electrical points require a cpc (earth wire) whether used or not

If you have an opportunity to provide an earth wire I would do so whether it's "written" or not.

 

[alasdairp]

I thought that "double insulated" allowed two-core flex and non-earthed chargers, etc, but the installation connection point (socket or ceiling rose, etc, including the switch) had to have the CPC present and terminated in some way (not just cut back). I did not this specifically mentioned. Any two-core installed cables I thought had to be SELV (i.e. no more than 50 volts rms - and floating w.r.t. earth).

 

[Jjc]

But where is it written? I'm not being pedantic, I can't find it in the book.

If nothing else its good practice. If the cpc is not terminated to the fitting then stick it on a terminal block . It's then available for future use. Why cut it off?

 

[sheppertonspark]

Since we are debating this here is my quandry. The regs say every item of equipment and accessory should have a c.p.c. available, common sense particularly for the situation originally posted, changing class 2 fitting for class 1. Problem is if you introduce an "earth" to a double insulated enclosure, by definition it is no longer double insulated. Can anyone answer this ??
