Hi Don:
Not a good idea. There are a number of fault conditions that can cause Neutral to be tens of volts above ground. Tom's
circuit with a Meg in both the Hot and Neutral lines is much safer for you equipment.
Have Fun,

well, grudgingly. only need the 1 meg to the hot side of the line, no
connection to the neutral needed, with 1 meg in there, normal ground
connections are going to supply the low side...It still lurks...

Come on, folks. never hook anything directly to the power line. The
source is just too stiff. Use an opto. I used fiber optic isolation
with
my big DC power supply.

I used to agree, until actually tried it myself. Now this is how
I do my picPET 60 Hz data logging:
