Class 2 light fitting

Is this because of the lack of cpc?

Essentially yes, I was questioning it because class 2 is, in my experience referred to as double insulated, the symbol is a square within a square..
This at a glance, to me, being an unearthed fitting with exposed conductive parts and single insulated cables hanging out of the back of it seems like a class 1 fitting, and a fairly poorly designed one at that. Were it class 1 it would need a CPC to earth the exposed metal.

As in the replies this is likely reinforced insulation.

Personally, reputable brand and reinforced insulation or not I'm not a fan of it. Especially when you can get something aesthetically similar with a hinged LED panel, push fit connectors internally and a grommeted entry for the t&e for similar cost.

If I had to fit these, I think I'd fit a fast fix circular box into the ceiling above it, directly above the cable entry, and connect to the T&E inside that.

Saxby were a reputable brand seems like they are now just badging junk from China.

solved by specifically telling you not to connect to the cpc of the supply….. where an unknown fault may have introduced a voltage potential to that cpc.

I see. So the view is that the risk of a fault energizing the cpc -> appliance outweighs the risk of a fault in the fitting energizing the small metal plate.

If properly designed to class 2 requirements, the risk of a fault from the fitting is (should be!) minimised.


Just because something is “made in China” does not necessarily make it low quality….

Chances are that it will be, though.

The Chinese will make what the customer asks for. You want cheap crap, they'll make you cheap crap. You want quality, they can do that too, but it'll cost you. Unfortunately, most people put cheapness over quality and that's why the markets are flooded with this stuff

It's a recognised reputable brand, not some random Amazon rubbish.

Predominantly in southern China and India.

You only have to look at it to see its rubbish.

I wonder if that metal tab sticking up from the back of the lampholder is actually an earth terminal. Some plastic holders had an earth terminal fitted.

The metal tab looks to be connected to the case.

That's how they were an L shaped bracket that held the holder and fixed to the lamp base and it had a poor quality earthing point at the top. Like this.

The designers of the fitting cannot guarantee that rcd protection is in place, or if there’s even a cpc present…. So they design their products to class II to cover any eventuality.

It has to have those to be compliant.

Crikey, that's a pretty rough design.
Well done for refusing to fit it. Basic insulation shoved under the floorboards! A small nick on the basic insulation and it comes into contact with a non earthed piece of metal... scary design.
I wonder how it can have a CE marking? I know nothing regarding the CE standards, but they can't be very high if this product meets them.

Not basic insulation. Looks like reinforced insulation.
Used on some GU10 lampholders, floating freely in a ceiling void
