Being an EV person, I have been asked to consult with adding EV charging to a new community center in my town. We are installing conduit from the electrical room to 4 spaces in the parking lot. For a cost effective, general solution, we will probably install one of the ClipperCreek Dual HCS-60 devices. This a nice setup with a pair of the HCS-60 EVSE's on a mounting pedestal offering a 48 Amp J1772 to each of two parking spaces. Because these are not more than 60 Amps and not more than 150 Volts to ground (each leg of the 208 Volt circuit is only 120 Volts above ground), the setup does not need a "Disconnecting Means," which simplifies installation.
For background, here are two quotes from the 2014 NEC:
For the other two spaces, we will probably apply to the Tesla Destination Charging program for a couple of HPWC's to set up for 80 Amp charging; also, I have a 70 Amp ClipperCreek J1772 that I may donate to the cause. Both of these options will need a "Disconnecting Means" for currents over 60 Amps. I have found devices like the GE 100 amp 240-Volt Fusible Outdoor General-Duty Safety Switch-TG4323R from Home Depot. Does anyone know of any smaller, better looking, and/or less expensive solutions for a "Disconnecting Means?"
Any other advice or suggestions are appreciated.
Thanks ahead of time, TMC!

625.42 Disconnecting Means. For electric vehicle supply 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 .
110.25 Lockable Disconnecting Means. Where a disconnecting means is required to be lockable open elsewhere in this Code, it shall be capable of being locked in the open position. The provisions for locking shall remain in place with or without the lock installed.
