I apologize to all for this question if has been repeated before (most likely) and is just reviving a easy answer.
Allaboutcircuits.com explains a split phase 240v circuit in the following version:
" An alternative solution would be to use a higher voltage supply to provide power to two lower voltage loads in series. This approach combines the efficiency of a high-voltage system with the safety of a low-voltage system...The current through each load is the same as it was in the simple 120 volt circuit, but the currents are not additive because the loads are in series rather than parallel. The voltage across each load is only 120 volts, not 240, so the safety factor is better. Mind you, we still have a full 240 volts across the power system wires, but each load is operating at a reduced voltage. If anyone is going to get shocked, the odds are that it will be from coming into contact with the conductors of a particular load rather than from contact across the main wires of a power system.."
Series connected 120 Vac loads, driven by 240 Vac source at 83.3 A total current.
If voltage in a SERIES circuit is additive why isn't there 240v across each load or at least on load #1
