well was i right or wrong??????????????
i need to know
I replaced a fuse panel in my old house with a modern breaker panel. It is 230 volt three phase. It has what is called a high or wild leg. This leg use to be allowed on the C phase but is now require to be on the B phase. Sound confusing. Try wiring some of your 115 volt stuff to the B phase and it can get real intersting.
But to answer your question can you make it work yes if the two 115 volts circuits are from different phases. Safe, correct or legal NO.
Bottom line if you don't understand electricity leave it to the pros.

holly crap you have a high leg system in your house?
i thought they were only used in industrial plants!
i do not think that is legal for a residential now, but maybe grandfathered in!
i ask the power company about three phase out here, and unless you have a farm they will not feed a house with three phase.
To add to confusion of a Delta 3 phase service the power company requires the High phase to be on "C" phase in the meter socket or CT terminal then switches to "B" phase at its first means of disconnect...at least in AZ
Edit: Sorry Phil I just reread your post. The high leg does come into the meter on socket on C phase and switches to B between the meter socket and main disconnect in my case. Evergreen had it C phase all the way thru.
So when did they switch back to C phase? I bought the panel from Evergreen Hardware. Weatherhead, meter socket and two hundred amp panel. This was part of installing a pool back in 1983. I had the inspector (Phoenix) red tag the prewired setup while he was out inspecting something else on the Pool. I already knew the high leg had to be moved to the B phase center leg just hadn't done it yet. Only thing done was it was mounted on the wall so I'm not even sure why he even looked at it. Still using the old fuse panel 4' oever. Moved it 4' to keep from having a 16' weatherhead. At that time it was 10' from waters edge or 16' in the air. I perfered the high leg on the C phase because is made it easier to use two pole breaker on the top and bottom buses. Dryer and stove both had a neutral. I know on the dryer if I was sure that the motor leg wasn't on the high leg everything was alright. But not sure all dryers are wired the same. Just didn't want the dryer to spin to fast for a short time So is blue still the color for the high leg?
I did this work as a home owner which is legal. When talking to the power company (SRP) they told me to go ahead and switch the overhead lines once I had it wired. then when I had a green tag they would come out and run new overhead lines. So I pulled the wires out of the old weatherhead and spliced then to the leads from the new weatherhead hot. Not sure what the transformer was fused at but I doubt it would make any difference. To this day I still can't believe the power company told a home owner to do this. Thinking back I wonder if my ex now wishes I had made a mistake
i think buy NFC it has to be orange!

I believe 480 is brown orange yellow.
208-230 is black blue red. With Blue on the B phase
No reason for you to get backfeed on the ground. In this case the ground is an equipment ground only and should have no potential unless there is an equipment failure.
If you get a 110V from each phase, it will work fine. If you get two 110V from the same phase, it is like running two parallel wires from the same place - and the only place it has to go is to ground since you don't have a neutral.
Okay now I going to have to see what color I marked the B phase at our old house. It's only been 28 years since I wired and it passed inspection so I could be wrong and I had to mark it orange. Because HVAC is my tradeoir or use to be before getting a goverment job where I'm not sure what I do the only place I got into panels and wiring was my own home.
