double pronged outlets, how come they are never plugged in wrong?

Question

So in England we have the ground prong so our cables are all the same, however I know in the states and other places they don’t, so how come no damage is caused if the positive and negative are the wrong way around?

Answer 1

Exactly like the other poster said. Our outlets are polarized with one slot slightly larger than the other. For applications where polarity is important, the device’s plug has one blade larger than the other. Some simple or older devices where polarity doesn’t matter may have a plug with both blades the same size.
