I am puzzled by this disclaimer for the $173 Leviton cord/handle set: "The J1772 connector assembly is not to be used as a replacement for a Leviton EVSE. Please check with the manufacturer of the EVSE to ensure compatibility.". Perhaps Leviton bought a lot of these cables, but then never used them for their EVSEs (maybe because they are TOO bulky)? There is an NEC requirement (Article 625.19 -- Automatic De-Energization of Cable) that Level 2 EVSE cables have "breakaway" protection, but I don't know how this is typically implemented -- perhaps this was a factor?
It is also interesting to read the comments of a buyer: "This cable is 3x thicker than the cable that came with the stock L1 charger. The three 10AWG wires weigh a lot and are wrapped in twice as much insulation as I expected. Those thick wires are bundled with multiple fibrous reinforcement strands and then the whole bundle is covered in an extra thick outer jacket made from some of the toughest rubber I've ever encountered. The advertisement photo doesn't do a very good job of showing just how big this cable really is. The plug is equally stocky and operates very smooth.".
I measured the diameter of my 2011 Leaf portable EVSE's cable as around 11.5 mm and that of my Blink's cable as around 15.5 mm. Anyone have a diameter for the 2013 Leaf's portable EVSE cable? If the buyer is correct about "3x thicker"...!!!
I would think from the standpoint of robustness a stiff cable should hold up longer than a more flexible one if that reduces the flexing that the internal copper wires receive over time (assuming these wires are constructed the same) -- so this might be a good buy. But then why the disclaimer?
Edit Update: I just measured an Eaton DC QC cable as ~33 mm, so unless the 2013 portable Nissan EVSE is significantly thinner than than their previous ones, the buyer's "3x thicker" statement is likely quite inaccurate.
