Does a local disconnect need to be installed within site of the EV charging post? Couple comments:

Interpretation of NEC 625.42 as it relates to 110.25 and 625.19

Working on a project that has EV charging posts on a different level than that of the EV charging cabinets and electrical panel in an existing parking garage.

Based on NEC 625.42, 110.25, and 625.19, Does a local disconnect need installed within line of site from the EV charging post? Couple comments:

1. The MCB for the system is lockable in the open position
2. Signage would be provided on the EV charging post level indicating the location of the MCB
3. The charging posts are de-energized until a handshake occurs between the car and charging cable.
4. Is the issue serviceability, emergency, or both?
a. If it's serviceability, then I would think local disconnects at the EV charging posts would not be required (based on the fact the MCB is lockable in the open position).
b. If it's emergency, then the average person will not know how to shut off power regardless of where the disconnect is located.
 
I believe to comply with 625.19 the manufacturers have this covered by being built into the equipment. So, if the equipment is rated more than 60 amps then a disconnect is needed, IMO and it must be lockable in the open psoition

625.42 is now 680.43 in the 2017

625.43 Disconnecting Means. For equipment rated more than
60 amperes or more than 150 volts to ground, the disconnecting
means shall be provided and installed in a readily accessible
location. The disconnecting means shall be lockable open in
accordance with 110.25.

I merged the second thread with the first thread since there was more info in thread #2. Of course, that was after I posted. :D

As far as NEC 625.19 is concerned, what if a control cable was used in lieu of a local disconnect?

I think that for over 60 amps the control cable is not acceptable but I am not certain. Sounds like it must be lockable in the open position... I guess if the cable is lockable you may have a case. I would check with the local ahj.

625.43 seems to want a separate disconnect but that is my interpretation.
