TRANSFORMER 240V TO 480 V THINGS TO KNOW BEFORE YOU BUY

Should the three-prongs are angled in order in order to be plugged right into a 3-prong 50A receptacle Then you definitely are right in that it would have to have a developed-in jumper as well as 120V neutral & ground can be tapped off the identical wire. I do not see how the item might have been given its CSA listing if which was the situation.
