Electrical product advice needed

[A_Camera]

Hi All,

I need some guidance on electrical safety of products rules. I have made a lighting base for a glass sculpture. It is a sealed LED driver and a 20W LED chip on a heatsink. There is a fuse in the mains side and the mains cable and switch are purchased prebuilt. The cable is with an earth wire and the driver is earthed to a common point on the terminal block, which is connected to an aluminium base plate. I cut the base plate on CNC and there are plenty of ventilation holes, but strategically placed so that it is difficult to reach a mains voltage through them. The sculpture base is either bronze or cast iron and it has the base plate bolted to it. I will have the finished units PAT tested, but I am wondering if there is any other official process I have to go through before they are offered to the public.

The pictures attached gives you an idea of the bases, but one pic was of a failure of the resin embedding of the glass, so doesn't show the base underneath. The second one was a brief test of the lamp.



Cheers,
Rob

The answer is yes. If it can be plugged into mains and not fed through a commercially available power supply with low voltage then you should not continue with this idea, unless you can certify the product and know what you are doing, which you obviously don't. Even at low voltage there is a risk for causing fire if the used material is wrong, or you make a design error, so even if it is fed with an approved PSU you can still be liable. The regulations concerning electricity are not just some rules and regulations, but law, so breaking those are pretty serious. If your product can't, or won't be certified to follow the regulations then you are not allowed to sell, and if you do then you are taking huge risks. All those rules and regulations can't be explained in a few words on an Internet forum.

Now, it is no secret that I am not a UK resident, but I am pretty sure your regulations are just as stringent as ours here in Sweden.

Good luck.
