To Fuse or Not to Fuse... That is the question!

Now you’re getting close. The signal is an electromagnetic wave. Obviously, since the signal travels at near light speed. And signal must be photons because all (rpt all) electromagnetic waves are comprised of photons. And you don’t have to be a rocket scientist 🚀 to see electromagnetic waves must be photons since photons are the only particle that travels at light speed in a vacuum and near light speed in a metal conductor. That’s precisely why satellite communications signals (electromagnetic waves) travel at light speed in a vacuum. That’s why there’s a satellite delay for synchronous satellites. Follow?

You are improperly applying quantum electrodynamics to our EMR discussion, mainly because you don't understand it ... and frankly, NONE of this matters to fuse directionality since the field, whether classical physics based on quantum based, still moves in both direction across the fuse in equal magnitude.

You are a square peg/round hole sort of guy, even though we are talking about apples and oranges.

If you want to be pedantic, QM does not at this point adequately described many aspects of conduction, i.e aspect of super conductivity, etc. are not adequately addressed, so your "all must be photons" is a leap you are not qualified to make for conductors. 

Tell me, if the field travels outside the conductor, and the energy is outside the conductor, where are the photons generated and received? ....

This conversation can serve no purpose any more.

Why? Because you are starting to realize that you can't just throw up some terms in hopes of baffling me with BS?  ...

Energy passes through that fuse in both directions ... it has to. The voltage potential reverses direction and the EM field must change direction as well. Electrons move in the fuse in both directions, and the EM field in bulk will be the same. Add in that most power supplies are symmetric for both polarities of the AC line. Energy is (line feedback excepted) transferred only from the AC source to the equipment but sometimes it enters through the fuse, and sometimes, the fuse provides the exit path. Either way, it is always there, and always has an impact no matter the polarity of the AC. It is always acting as an element in the circuit, in both directions, and equally.

@roberttcan, I take it therefore that fuse "directionality" is, you would argue, impossible?
