Plugs with the two of the same-sized prongs are considered non-polarized because there is no clear distinction as to which prong is for the “hot” side and the “neutral” side. By having the two different sized prongs or a three prong design, the electrical device can only be inserted into the electrical outlet/receptacle one way.

Furthermore, why are some plugs polarized? Reversed polarity leaves the circuit open and could potentially lead to electrical arcing or shocks.

The standard residential outlet in North American homes is the NEMA 1-15R, which accepts both polarized and unpolarized plugs. The hot, neutral, and ground wires are intended to complete the electrical circuit in a specific way as shown below. It is entirely likely that you have some appliances or other devices around your house in which the plugs have blades of equal width—nothing to distinguish neutral from hot. Designed for light duty plug replacement and repair. Polarized receptacles are similarly designed with inlets of different sizes so that you can only insert the plug one way. Perfect for use Where You Want it plugged in Flat Against The Wall or with a Power Strip. Some of your electronic devices may have two identical prongs, two unequal sized prongs, or even three-prongs. An appliance with a nonpolarized power cord also has a NEMA 1-15P plug, but the prongs are identical, so it can go in either way. All rights reserved.
