English term or phrase:hot wire or hot cable
The hot wire in any electrical circuit is that conductor which can only be de-energized by opening the overcurrent protection device. In other words, if you remove every device in an electrical box and undo every splice, there will then be one and only one wire which has current on it in that box, per circuit, when all of the circuit breakers are on or all of the fuses are in place. I said "per circuit" because more than one circuit may feed any given box. This is very rarely done. If you encounter it, you should almost certainly stop work immediately and call a licensed professional electrician.
