Have just been perusing the MK Electric on-line catalogue and was checking out their
15Amp 127V Socket Outlets . The
data sheet describes them as “American Style” yet they are rated 127V and are not UL or CSA listed. The standard covering their design is given as SSA: 444: 1985. Which standards authority is SSA? It might give me a clue as to the intended market for these devices.
Other interesting difference with the NEMA prototype is the shuttering of the slots. I would also be interested to see how the terminals are labeled. ‘L, N, E’ I suspect from the datasheet though it is not that clear. No mention of brass and silver terminals as I doubt the intended customer uses white as the neutral/grounded conductor. Polarization is the same but I see that outside of America, the earth pin is definitely up!
