DESCRIPTION:
Video response to EEVblog #279 where Dave talks about pitfalls when connecting your oscilloscope's ground lead to your circuit. Great video, but he left out and especially sneaky scenario which has caused problems for me (and others I'm sure) in the past. Sneaky because it looks fine on paper, but the problem arises because of the way homes and offices in the US are connected to mains. I'm not sure how many countries are like this, but I know there are at least a few, so worth watching and being aware of regardless of where you live.
