I’m not sure I totally understand the question, but a 240/120 panel can not have 480 volt supplying the panlel itself. The 480 oftenh supplies the transformer which then suopplies the panel with it’s rated voltage (208Y120)(240/120, etc). On second thought perhaps you are asking if a three phase transformer can supply a single phase panel, if that is the question, yes.
