Just a confirmation, with the 120/240 single phase system like below if there is a load of for example 1700w on Line B and a load of 1500W on line A total current on the neutral = 1700 - 1500/120 = 4.1A?

Does anybody know of a diagram of the 120/280 system? This thread is kinda hard to read without the quotes in bold [Linked Image]

Is it like this without the extra phase?
