The BS standard are a guide, you are correct although those standards are more than a match for most CE directives. However UKCA & CE ( both High (above 50Vac) and Low voltage directives) are law and therefore anything mains cable without a fuse here or non compliance in any other aspect of that directive in the UK is breaking the law. Chinese CE is pretty much close to a chocholate teapot effectiveness for many ali express procured items no arguement from myself on that.
As the company legal department points out, "Type approved CE the onus is on YOU to prove compliance in any court proceedings, where as granted CE approval the onus is on trading standards to prove you are making non compliant goods"
So ANY public individual is entitled to view a build manual for products providing they are no patented or trade secrets which would be open to copying. However in a court of law all information is availible.
You do have a build manual for said product I trust?
The issues also arises if the fire causes loss of life and or damage to adjecent properties etc.
Mind you I have always felt that any review sites should have to publish the CE documentation for any Product review by them
Cables falling within the scope of the Low Voltage Directive (generally those from 50V up to 1000V AC) must be CE marked, the relevant EC Declarations of Conformity made and Technical Files created and held by the relevant party manufacturing the cables or placing them on the market in the EU.1
I would suggest chatting to these guys in repsect of this Tim
