I have discussed this here before, but neither the Lectron or the A2Z have a proper mechanical interlock, meaning you can literally rip out the NACS cable while HV is still present, which could result in an arc flashover between the terminals with full pack voltage. This could generate over a thousand amps of fault current and even completely destroy your EV!
The CCS standard requires a mechanical interlock that prevents the removal of the CCS whip while HV is present. This is enforced by a motorized latch in the car. But there is no mechanical interlock on either of these adapters, which means the connector could be removed under load! So if you ever use it, please supervise it the whole time (do not leave unattended!) and do not disconnect the NACS able from the adapter until the car unlatches the adapter from the inlet, only then is it safe to remove the NACS cable.
