Hi, I'm a few weeks away (hopefully) from my first Tesla (model S LR) and about to have the Tesla wall charger installed in my garage. Has anyone experienced issues as a result of charging at home? We have 200 amp service with the major electrical draws being central air and a double electric oven, everything else runs on natural gas. The wife is concerned about the impact charging could have. Our local utility provides a pretty good incentive for off-peak charging so most if not all will be done overnight. Thanks
