When we talk AC voltages, we use root-mean-square (RMS) since the actual voltage is constantly changing. The RMS gives you a phase "average".
You get about 115V phase-to-neutral, and a about 230V phase-to-phase.

I saw somebody do that once...I also saw a 3,000Kw turbine generator jump about four feet into the air
