Hello
I came across this video on youtube where a guy was switching a lightbulb on and off with an arduino and a relay ().
I was bothered by how he left out the phase wire (look at the image at 4 mins and 53 sec in). People mostly seem to be complaining about how he is breaking the ground wire, and I can see why that is wrong too, but shouldn't he also be using all three wires aswell? Even if he was breaking the phase wire and left out the ground wire then wouldn't it be unsafe to use this "adapter" with appliances that need to be grounded? If I were to do this then I would try to make the adapter like an extension of the wall outlet by connecting all three wires in both ends and breaking the phase wire, that way you could use it for appliances that are either grounded or not. Am I right or wrong?
Also, I saw another video of a guy who was switching a light bulb on and off in the same way and he was using a plug that looked kind of like the 2 prong euro plug (he had wired it up himself). To do this safely, you would have to look for a lightbulb/socket that are double insulated right?
Regards
