I received a bid for installation of a wall connector. I am bidding it both with 60 amp service and 100 amp service.
The electrician is only adding $350 for the 100 amp breaker and wiring, however he is noting some potential additional costs that the city might require- load calc and a concrete encased trench + $875.
I have a feeling the load calc and concrete-encased trench could be avoided with the 60 amp service so I am debating whether the 100 amp is worth it.
I certainly don't need 100 amp for my model S given my commute. My only reason for kicking it around is that there's a good chance we'll pick up a model 3 at some point.
Having said that, the 60 amp will still charge pretty fast and neither me nor my wife drive that much that we'll absolutely have to be charging at the same time.
I think I answered my own question - no - it's not worth it, but I'm open to any input before I make the decision.
