Re: CQD answer published Tuesday, August 20, 2019 -EVSE
Regarding the Mon 8/29 vehicle charger question: I assume that Greg meant that "It does NOT look like there is any protection . . . " - AND more critically, I assume that these "ran several hundred feet" cables are not for building system voltage, but rather for carrying vehicle charger output. (This would be a first for me, I have never seen vehicle charging cables longer than 20 to 30 feet long).
I have to assume that he is writing about cables between the charger and the vehicle - I believe that these would be "Output Cable to the Vehicle" defined cables with an "Electric Vehicle Connector" at one end. As such, I believe that they must be a part of a factory designed, built, and listed assembly.
These exceptionally long cables might be field-construction allowed if installed in accordance with listed installation instructions. In this case, I believe that the protection for the cables is within the charger. As I understand it, chargers run several cable safety/function tests after the connector is inserted into the vehicle charging port before the charger will energize the actual charging conductors which are also in the cable.
