Actually being a 120/240 split phase power system, it depends on where the neutral was broken, and whether two devices were each connected to a different hot, and on whether those two devices were both turned on.
Looking at the pictures, if one of the neutral wires on the left side of the neutral buss lost continuity with the buss bar, then there would be zero volts on the device(s) connected to it. But if the neutral wire on the right side of the buss bar (the source neutral) were broken, and the neutrals on the left still intact, and there were two devices with each one connected to a different hot, and both were turned on, then there would be 240 vac across those two devices since they would effectively be connected in series to the two hots. The neutral buss bar would be floating. The actual voltage applied to each individual device would be dependent on the impedance of each, not 240 vac to each.
