I think maybe I wasn't clear.
A couple EVSE manufacturers told me I couldn't use their charger outside with a 6-50R despite knowing full well (per my electrician and you guys) that it's perfectly ESA legal and safe when used with a weatherproof receptacle. They said water would get in, it might malfunction, they'd void the warranty, etc. They could only be hardwired which is BS. Them not knowing this doesn't give me greet confidence in their product...especially if I did buy one, used a 6-50R and needed to warranty their product. Would be a nightmare IMO.
Elmec was NOT one of these companies. In fact, they seemed to encourage 6-50R so the charger could be portable if need be. The had an answer for every question I had an seemed to really know their product intimately. For that reason, I think the Elmec is the one I would buy. Plus Canadian company.
