The heat of the fire is not completely transferred to the cooking utensil due to air and losses, on induction and resistive stove tops, the heat losses are much lower since you don't heat anything in inductive (magnetic field heats the metal directly), and electric stovetops have no air-gap to transfer heat.

So, in the end, 90% of the time you're looking at the same cooking duration at the end of the day. So, you don't need that 120A load.

In other words, if the box says 5 minutes on medium, it's 5 minutes on medium. Regardless of gas, electric or induction.
