Can you elaborate on this? NEC says neutral isn't to be switched. "You wire a switch to make or break the supply conductor-also called the hot lead. The NEC specifically bars switching the grounded (neutral) conductor or the grounding conductor [404.2(B)" From - https://www.mikeholt.com/mojonewsarchive/NEC-HTML/HTML/Article-404-Switches~20040624.phpFor reasons I am not so clear on is when you just switch the "hot" and leave the neutral hooked up it will build up stored energy, then when that switch is flipped it discharges or de-energizes.
Not true.just switch the "hot" and leave the neutral hooked up it will build up stored energy
Sorry, but that's complete nonsense.I kind of figured It would go this route. Yes it is true. I have a hammond transformer that will do this unless the Hot and neutral is switched. However one way or another I had this problem; someone on another form explained what was happening and told me to switch both hot and neutral and then the power supply never had problems with blowing fuses or tripping the breaker.
Of course they do.Nope I am not breaking the laws of physics, I will give you a hit, opposites attract.

Maybe we need to consider a third -- a winding shorted to the core?Not true.The are two common reasons for blow fuses or breakers when energizing a transformer.
One is if there is a rectifier on the output with a large filter capacitor, which causes a high inrush current to charge the capacitor.
The other is the high initial magnetizing current pulse that can occur if the transformer happens to be energized near the positive peak of the sinewave.
The only use I can think of for dual primaries is; universal mains transformers - they had 2 identical primaries that you wire in parallel for 110V and series for 220V.On a off note here, when you have a transformer with dual primaries and dual secondaries; if you have primary coils wired parallel and the secondary coils wired in series (plus the rectifier and reservoir capacitors) you may experience problems with it blowing fuses and popping breaker. For reasons I am not so clear on is when you just switch the "hot" and leave the neutral hooked up it will build up stored energy, then when that switch is flipped it discharges or de-energizes. If you have problems with this you will need to switch both the hot and neutral. I had this problem till I found some information on another form. You can also add resistors (a load, parallel) on the primary winding, secondary windings, and from rail to rail and rails to ground etc
I am sure there is someone who could explain this, but it sure is not me!
So your saying miles and miles of underground water pipe is not sufficient? What would you consider a good ground to be?NEC also says it is ok to use water pipes for ground???
You do know that 220V uses two hot wires don't you? And that computer power supplies are switch mode supplies, don't you?I think they are referring to safety ground which is not the neutral wire. Also In computers and audio equipment they switch both contacts almost always. Mainly because it is able to be both 120v and 240v. I get a lot of double pole switches out of computer power supplies.
There is a third reason. You don't understand how AC electricity works.You will just have to assume I am making all this up and that I am a liar or crazy.
If I cut the ground in my cable I hear a loud hum and it is not coming from my guitar.Ok let's make it simple! Ask any musician with no knowledge of electronics, if they cut the ground from there guitar to there amp can they still hear there guitar in there amp.
I can transmit AC with zero wire.Then prove that you cannot transmit an ac signal across one wire.
Are you an Internet troll?I am going to intentionally drag this out and see what someone best proof against my claims are. I am telling you all disprove me with science. Get out your bread boards, text books, reference material, calculators etc. I encourage you to try and duplicate my claims or disprove them!
If that's what you want to do. Just rememberwith 56 posts I don't think so.
A drill instructor would create ridiculous and seemingly impossible tasks and not give me any answers, in order to teach me to go an find a solution to problems. When people ignorantly try to insult you and are critical or you, then you simply give them no answers; for you have not found a friend but an enemy. I do this out of principal. I know there are some smart people here but they don't know everything. I want to test there science.
Mods, please split this nonsense into its own thread. It doesn't appear to break any of the TOS, but is nonsensical. As such however, the TS challenge may prove to have entertainment value.Sure accidentally touch only the hot wire and what happens? Sure accidentally lick the neutral and what happens?
Yes you can use the hot if you phase shift the signal then hook it up to the other prong? Opposites attract? However the filter or network will have to be able to react to the total amount of power the load desires or there will be a voltage drop. In other word split the wire into two signals hook one end up to a low pass and the other to a high pass filter, tie the outputs of the filters together to get your sum of the phase shift networks. You can then insert a load in series between the networks or tap in the center of the networks and the unmodified signal. However it is less cost effective to transmit power this way.
