In your thread on legal actions against KNC you say KNC boards need a CE marking. But only devices that fall within specific CE directives need CE markings.
I cannot see how the KNC miner falls under any directive. It is not a medical device. It uses 12V which is well under the directive limit of 50V. It is irrelevant where the 12V comes from.
Yes, I see that and that's why I have written "may" need CE marking. However, why would a 12V halogen bulb have the CE marking?
I am also wondering whether there are other regulations besides CE. A company cannot sell something clearly dangerous to its customers without warning.
The law and regulations also often don't like if they are "side-stepped" in a shady manner. That's what I meant with the missing PSU. Example: I have a free capital gains tax allowance per year. If I try to crystallize gains by selling and quickly buying again, then the tax man argues that this was only for tax reasons and hence void. I understand tax laws are of more interest, but I believe a similar principle may apply here.
Having to include an imaginary issue around KNC breaking the law over CE markings, because it does not also sell the power supplies, does not seem helpful to your case.
No, my case is not built on this and I don't need to include it. The consumer vs. business issue may be the most promising route. I think the fire hazard and low safety of their equipment simply adds to the case, as it is a very good reason for a consumer to cancel an order.
