Any tips on wiring for a 240V charging station?

I am currently dragging an extension cord across the driveway to charge my 2017 Volt at 120V. I have been working with an electrician to do something more permanent, bearing in mind that I will want to do 240V in the near future.

Are there electrical code gotchas my electrician and I need to know? I was thinking of a 240V/30A dryer-type receptacle in some kind of weatherproof enclosure at the corner of my porch. I was going to make a wooden box big enough to house the receptacle and the charger.

I tried to read the electrical code myself (NEC Article 625), but it's pretty tough reading. At least I know the driveway has adequate ventilation! (625 spends a lot time talking about ventilation)

Thank you. I'm a new member of the forum, and my search queries didn't seem to find an old post that addresses this.

If you can afford it, get a pedestal-style EVSE and hard-wire it. Weatherproof and has cable management.

There are some threads on here about how various people got around having their EVSE out in the weather. I saw one where they put a hole in the house wall with the EVSE inside and the charge cable went through a 4" plastic pipe. Several have used a plastic tupperware-style tub with grommet holes.

The guy on EVTV made his look like a gas pump.
