Same principles, just the stakes are higher, why not

So he said the last line will cause a direct short. Really? One line is hot and neutral so if there is ever a direct connection, I’m thinking it would be a return path for the power.
If it were 3 phase, and phase to phase connection then I would agree.
If I’m wrong, I’m all ears for an explanation.

That's why it's called a ladder diagram and not a stepladder diagram. The ladder concept is: components are the rungs and the transformer is the dirt/floor it's sitting on.
Use the biggest hammer you like, pounding a square peg into a round hole does not equal a proper fit.

Gets a bit more tricky with power coming at you from to different directions.

Yes exactly
Working on a device now that puts the magic smoke back in
Unsuccessful at this time l just keep time traveling
Dang you can’t have nothing

There is a replacement smoke kit for british cars, so maybe someone will make one for HVAC.

For a more dramatic answer: Cut of the power cord to a lamp, twist the wires together and then plug into any nearby outlet. The lights going off will be due to the circuit breaker seeing a dead short. The same would be true for your transformer, you'd be letting the smoke out and that voids the warranty.

There is something wrong, or maybe I should say 'not complete'. It's very likely, if you were at the stat, there was something not connected at the unit.
If you have a normal system and the operations are normal, and measuring from R to Y on the thermostat, you would get ~24 volts. The main reason is because with the newer stats out these days, you have to pull the stat off of the sub base to get to the connections.
On older mercury bulb stats you could often get to some electrical without unscrewing the stat from the sub base.
Usually when you see something like 3 volts, it's because of the meter. Meaning, that if you had an old analog meter, one that actually a needle that moved instead of a digital readout, you would see zero volts. You see, the meters we typically use every day are EXTREMELY sensitive.

What causes this? Sorry for getting all theoretical.

I do a triple evac with nitro to remove non condensables.

Let’s have more fun and throw dual (RA and SA )smoke detectors in it! With 120v powered fire dampers connected to the load side of the GFCI Lol..
