# US Non-Polarized Plug Dimensions [duplicate]

for academic purposes I'm doing a very specific task where i need to calculate the Cell Constant of an American Non-Polarized Plug, ie, without same length the prongs. So I need to know what are the dimensions of it, namely, length, thickness,wide and distance between the probes.

I cannot get the dimensions for this plugs anywhere on the internet , only from polarized ones, so if any kind soul with one at home could give I would be very appreciated. Thank you.

• There aren't supposed to be any non-polarized available anywhere, except grandfathered in on very old devices. – Ignacio Vazquez-Abrams Jun 15 '16 at 17:57
• You'll be close enough if you assume the blades of the non polarized plug are the same as the narrower blade on a polarized plug. – The Photon Jun 15 '16 at 18:17
• There are polarized non-grounded plugs - they have the wider Neutral pin, but no ground pin. I have some power tools and a two-wire extension cord that have these plugs (No, I didn't break the ground pin off!) – Peter Bennett Jun 15 '16 at 18:43
