I am assuming it is due to requiring more electricity but I’ve had broken 3 prongs work with just 2
In: Technology
When you plug in a three-pronged plug, that third prong is providing an alternate pathway for electricity in the event of a fault. If you cut the third prong off of a plug, you defeat the safety feature. Also, adapters were designed to use the cover screw to complete a ground circuit on some older plug designs.Aug 20, 2015
