As a cost saving measure they have reduced the wire size. Lets face IE, 12A only requires a #16 wire. The #12 of the older units is great for upgrading.
Not to contradict a long-term member, who I respect, but it wasn't until '15 that Nissan cheaped out and switched to 14 gauge wiring, still heavier than many other mfgs. as you mentioned. They did change the j1772 wiring though to use a more rubbery wire post '12, pre '13 it was more shiny and prone to getting stiff in sub-zero temps. Also of note, they changed the temperature rating of the wire from 105c pre '13 to 90c post '12.
is if the OP indeed has an upgraded '11 it will do 20a L1/L2 on Leafs that support those speeds(and no way to manually dial it down). As an '11 or '12 Leaf will only charge up to 16a L2 and a meager '12a @ 120v I'm thinking thats why he said it only goes up to 16a :)
I have an a old upgraded '12 Leaf EVSE and it indeed charges at 20a 120v and 20a 240v, the 20a @ 120v is a real caution as you really need a 30a circuit(which isn't very common) even on a good 20a breaker things will get warm and I'd only suggest it for a short period of time(<1hr).
