    Measuring Power Lines Noise

    Thanks! I'll repeat the tests over the weekend when I can turn all lights off and perhaps most of the breakers off as well and then try to figure where it is coming from. What would I use as a trigger during the power up cycle if I'm trying to measure peak current? I'll have 2 channels...

    Well I must have been doing something wrong yesterday night because now it is working--i.e. I can read the phase, neutral and ground and they all seem reasonable readings. Ground has very little noise. The neutral has quite a bit. There is some noise at the peak of phase but I can not look at...
