I need to have a discussion with the crappy Owner Advisor & Delivery Experience Specialist who did not educate you properly (or at all) on charging options.
Your car has an onboard 48A charger unless you bought a used CPO somewhere or paid $1900 to upgrade to high-amperage.
The included Universal Mobile Connector which comes with the car can charge at a maximum of 40 amps. It comes with two interchangable plugs, a Nema 5-15 which plugs into any standard household 120V outlet, and a Nema 14-50 outlet, which is commonly used by RVs and/or electric ranges. You can also buy other plugs that you can install on the UMC. I have a NEMA 14-30 adapter (which is used for most modern household electric dryers) and a Nema 5-20 adapter (common in many commercial settings).
In the US, electrical code only lets you draw 80% of a maximum circuit amperage rating. Therefore, if you want to get 40 amps, you need to have a 50 amp circuit breaker. A regular nema 5-15 household outlet is rated for 15 amps (hence the -15), so you get a max of 12 amps. But at 120V, the charge rate is 9-10 times slower than a 40 amp 240V outlet.
The Tesla Wall Connector can be adjusted to whatever amperage setting you like, it just depends on what you wire it at. My car charges at a max of 48A, so i wired it with 6 gauge THHN wire on a 60 amp circuit breaker and set the rotary dial in the charger to output 48A max. You can install more amps if you want, i.e. a 100Amp circuit that outputs a total of 80A, but if your car doesn't have this high-amperage charging ability you're wasting time. Not to mention 3 gauge wire is a much bigger pain to work with and 100 amp circuit breakers are like 5x more expensive than a regular 60 amp one. Its about 90/cents a foot for wire, and i bought my supplies at the local home depot with 25 feet of wire used and with appropriate PVC piping and supplies paid less than $50.
The cheapest install option is to install a NEMA 14-50 outlet. You can use the included UMC. If your sub-panel is in your garage, you shouldn't need more than 5 feet of wiring and a competent electrician won't charge you more than $150.
