Yeah I'm just using a standard Amazon mains usb to power the Arduino.
I just don't know what the law is regarding selling something with an Arduino and components I have put together with possible fire risks predominantly.. or does the risk stop at the Amazon adaptor in terms of responsibility? I assume the Arduino setup afterwards is pretty much safe with no risk of fire? Thank you for your reply
The English common law applies in the US and other former colonies! You can be sued for anything and need insurance to protect your assets, Get an adapter that is marked UL or CSA or similar markings.
Well you, as the seller, are responsible that the electrical equipment you sell meets current regulations, a defense of "I bought it on Amazon" does not sound very convincing.
You really need to consult a professional company that advises commercial operations, then you have some defense if things go wrong. "I got the advice from a hobby forum on the Internet" is even less convincing.
There are no legal issue with respect to Arduino itself (like,royalties or licensing or similar.)
As others have mentioned, there may be things like safety and radio Interference licensing and such. I’m not really sure how “art” works there - a lot of art seems to be more dangerous than a consumer product would be allowed to be.
Thank you all for your responses. Very helpful. I read read elsewhere on the forum that's applying as a kit. Helps get round legalities passing on the burden of responsibility to the end user.. any comments on that? Thanks again
