Except for Tesla owners, most EV owning visitors will only have a mobile L1 EVSE. Unless you plan to feed and house them overnight while they charge at ~ 1.1 kW, you will want to be generous and let them use your spiffy L2 EVSE. So this comes back to 1, placing the outlet in a central location that lets the EVSE cable reach any car in the garage; and 2, installing a nice beefy EVSE that can output at least ~ 6 kW (although I recommend 9.6 kW (a 50 Amp circuit.) if your panel box has room.JohnKuthe said:I'm only having three 240VAC jacks installed. Let people get their own charger for their own electric vehicles. I'm getting one for my 23013 Nissan Leaf!
Unless you are in Europe ? I gather that people do indeed wander around with their own EVSEs across the pond. Or is this a shared garage with tenants ? In the case of tenants, you may wish to have the electrician install a meter to each outlet for billing. The analog types that were a staple on homes for decades can now be bought for ~ $30 on Ebay.
