neutral current

Jim, I meant no offense at all.

But at the same time we have at least two ongoing threads, a couple of closed ones all discussing roughly the same issue.

The other threads dealt with voltages. I saw no reason that this one could not stay focused on currents.

For what it's worth, the argument of Vxy = Vyx@180?, is similar to the argument of 'do you size a load to 80% of the breaker or size the breaker to 125% of load'. You end up in the same place, but there are reasons to choose one method over the other.

Bob I had been in the Electrical trade 40+ yrs. before I retired and I have never seen that circuit configuration
that is very interesting. Just lucky I guess I didn't do that somewhere.

I could see how someone could mistakenly think to them self , hey I can wire it up like this and switch that 240
volt circuit with two switches from two different locations. Thats why it pays to draw a diagram before attempting to
a final hookup before or really thinking about it. Never know when your going to do something like that.

Thanks for showing me something new.

Same thing happens when you have fuses instead of a breaker on a service or feeder and one of the fuses blows, or even just a loss of a ungrounded conductor for whatever reason. On typical call for something like this it is often the water heater that is the 240 volt load causing the strange activity, turn it off and the open ungrounded becomes more obvious.
