Like I said everyone thinks they are an electrician. LOL
They are non polarised, they are alternating circuit. Plug in your DVD player, TV, hair dryer, or any electrical jack to a wall socket, left right or right left, why it still works ?
edit : however, for a professional electrical wiring job, a proper wiring arrangement should be done before powering every each of electrical outlet in a house, for. examples: left hole is always for Hot wire, right hole is always for Neutral, and middle hole is always for Ground.
