Even if he cut 99 percent through a wire, you'd still get a full voltage
reading . The dryer or airconditioner wouldn't work, but the no load reading
would indicate full voltage. The most puzzling thing is that its affecting
two independent cables and breakers. In the real world, that just doesn't
happen. let us know what you find. Good luck
