Advice on work I've had done

(b) for any other application, no it is lighting. The cable is undersized.

Why would you take the rule for the minimum size of a different type of cable?

Ok, suppose for a completely different application, you were using bare conductors (second row), but you were using it for a lighting circuit rather than power. Minimum size for "power" for bare conductors is 10mm (copper), would you go "ah, but elsewhere in the table it says lighting 1mm, so I can use 1mm for lighting circuits if I use bare conductors"? No, of course not.

First sort out what sort of cable you're using: ignoring bare conductor cable, is it flex, or not? If flex, you look at what the use of the circuit is, and size accordingly. If not flex, you do the same. You don't pick and choose "use of circuit" and then apply it to the three different types of cable listed.

Yes the use of circuit is lighting no matter how much you juggle it. Bare conductor sizes are irrelevant.

There could be a small chance that it is white FP200 but I am assuming that the OP has felt it and it is flex then its not good practice even if it is adequately fixed.

I think we're going to have to agree to disagree then.

My logic, reading table 52.3 (ignoring bare conductors):

Is it flex, or not flex?

If not flex, minimum size = 1mm for lighting, 1.5mm for power.

If flex, minimum size = 0.75mm, unless specified in the product standard for a specific appliance.

I thought 0.75 flex was only allowed for pendant wiring etc?

Put some photos on of the wiring

You got a reg number for that?

The only thing I can see specific to pendant wiring is 411.3.1.1, which is about not having a cpc, rather than sizing: "A circuit protective conductor shall be run to and terminated at each point in wiring and at each axcessory except a lampholder having no exposed-conductive parts and suspended from such a point."

Never really comment, just enjoying reading. Just wondering with all comments if 1mm is minimum allowed for lighting, how come 0.75mm flex is supplied with most pendants, surely this must class as part of the lighting circuit?

I'm going to have to go with Happysteve,on this one,purely on the basis of working backwards from a potential incident or investigation,the regs could not be straightforwardly used,to indicate an incorrect selection of materials,in this specific example.

The lighting issue evaporates,if the same circuit powered a garden sound system,of the same load

Dunno about that Mate, you should see the mess my 0.75mm2 shower circuit made of my mates new bathroom!!!!
