That doesn't makes sense. 24v @ 40A is "only" 960w. Once you figure in efficiency losses (~15%) and AC power factor, you should only need ~10A @ 120v. Maybe they recommend a 20A line because the load looks highly inductive (rather than resistive)? But this would show up in the power factor rating, but could be compensated via power factor correction circuits (most high -power/end computer PS units use this).
