So this is purely a thought experiment that I can't believe just struck my brain. I tried Googling this and tried searching for it in this foum but came up empty handed. I'm sure I'm not the first person to think of this.
What would your multimeter read if you placed one multimeter lead on a 120v leg of power and the other multimeter lead on a 480v panel's neutral bar?
Even better what would lets say a 120v incandescent bulb do if hooked up this way?
What would your multimeter read if you placed one multimeter lead on a 277v leg of power and the other multimeter lead on a 120v panel's neutral bar? And what would a 277v incandescent bulb do if hooked up this way? Anybody ever seen something wild like this?
Or even crazier has anyone ever stuck one multimeter leg on a 120v leg and the other multimeter lead to a 277v leg and seen what voltage pops up?
I can't believe I've never thought to try this stuff before and I am planning on testing this stuff out with my multimeter when the infrequent opportunity arises. And while tempting I wont actually try hooking up a load, seems unsafe lol. The closest I've ever done something like this is measuring ungrounded Delta phases to earth ground voltages before but that was years ago. If memory serves correctly I believe I got wild readings that may have been higher than phase to phase.
