    Seriously: the 4:1 ratio starts to fall apart as the core gets saturated. You see more leakage flux and mutual coupling from primary to secondary, so the voltage ratio changes. On top of this the saturation of the core means more magnetizing current flows and there is more voltage drop in the primary. I would expect a short duration transient (until something fails or OCPD opens) with rather less than a 4:1 ratio.

    We used wire up similar in the shop just to watch them blow up......
    Excellent comment Winnie
