How can we tell if our product requires a polarized or non-polarized cord? What's the difference? null

Hello there,

An appliance with a polarized power cord has a plug that matches the outlet. Only one way will it travel. An appliance with a nonpolarized power cord has a NEMA 1-15P plug, but the prongs are the same, so it can go either way. There are three prongs in a grounded NEMA 1-15P.
The rounded end of the pin is there so you cannot insert the plug into the connector incorrectly. The best way to tell if your plug is polarized or not is to look at it. If the 2-prong plug has two equally sized pins, then it is not polarized.
