I'm lucky that WI has adopted the national building code NFPA/NEC so a switch (disconnect) for an EVSE is not required unless it's ABOVE 60 amps. But I did have two electricians once tell me it was 'code' only to finally ask them to show me. Then it got quiet. I was initially putting in a 75A unit for a Tesla but at the 11th hour I bought the Bolt instead and went down to a 50A circuit for my first charger. I like your charger, I love that every part of it has a useful application all the way to holding the cable.
A simple service disconnect switch is about $10. I don’t see why it would be an issue to install one, certainly wouldn’t add much to the installation cost.

At the time that I was doing the installation, the only inexpensive service disconnect switch was only for 50A. Anything over 50A was a lot more. And at that point, my stupid math said a small load center was cheaper than a service disconnect switch rated for like 75A and I went that route. Of course, once I put breakers in it, it ended up being the same but the utility of it changed so it was no longer apples to apples. I ended up putting a 125A circuit in the garage so I could charge 2 EV's at capacity at the same time. It was affordable, because I did it myself.
