jinx! Mine was installed yesterday too, same setup with the UMC and 32a tail. My EDD is going to be much later than that though.
I had a lot of other stuff done at the same time, but the car charger bit would have been less than 1k - took the Sparkie a few hrs to do around 15m of cable in a reasonably complicated run, and required a decent amount of shuffling at the switchboard. Was done with the car stuff before lunch.
