What do you mean with disconnect? My charger has a switch on the side to shut it off and buttons to change when it charges.
Why do you think you need a disconnect? I mean the small chargers are not serviceable like an Air Conditioner which requires one.
Yes. The Disconnect switch is really not required for evse less than 60A (codes are minimum requirement). I did complete my installation first without buying the evse yet, so for me to be able to complete the wiring, the disconnect switch at the end gave me the flexibility to complete the wiring while deciding what evse brand to buy.
Safety Switch: For EVSE rated at more than 60 amps or more than 150 volts to ground, a
means of disconnect must be installed in a readily accessible location and within sight of the
electric charging connector. If the disconnect is not in sight of the equipment, it must be capable of being locked in the open position (CEC §625.23). Depending on local code requirements, a fused switch may be needed if the switch is not readily accessible, or is not visible
from the main panel.
