Hey guys, hoping I could get a little advice. I made a soldering fume extractor fan using a 240 V fan. The fan only had connections for hot and neutral. I was checking everything to make sure it was safe. I checked the prongs of the plug to the fan body and got open circuit. Then I plugged it in and turned it on, and measured from the frame to earth and I'm reading almost 60 V, which doesn't seem ideal. If I use the LoZ voltage measurement mode it's only around 7.5 V, but I'm not sure what that means.
I had a spare fan, so I wired it up separately and am getting about the same result.
Should I just use a three lead power cable and connect the frame to Earth?
Thanks
