Thank you for the answer. So, when you are measuring with your leads and trying to find voltage drop, are you putting the positive lead on the hot wire (L1) on one side of the load, then the other lead from your MM onto the hot wire on the other side of the load? Or do you put one lead on L1 before the load, then the other lead on the neutral wire on the other side of the load?
Are we always going to be putting the leads on one hot wire, and one neutral or ground wire? Or do we sometimes have one lead on a hot wire before the load, then still on a hot wire on the other side of the load?
I’m still a little fuzzy on how to actually test this with the MM.
thanks
