Your typical Level 1 / Level 2 home EVSE (i.e., charging station) can typically be plugged into a NEMA 5-15 (your average 120V outlet), NEMA 6-20 (240V outlet, not nearly as commonplace in your average home vs. NEMA 5-15), NEMA 14-30 (240V, typically used to plug electric dryers into), or NEMA 14-50 (240V, typically used for electric ovens and RVs) plug outlets, depending on the type of plug that comes with the EVSE--many portable (not to be confused with wall mounted home EVSEs like the Tesla one mentioned in this thread) Level 1 / Level 2 EVSEs include an adapter to plug it into a NEMA 5-15 receptacle.
As noted above a NEMA 5-15 is rated at 120V whereas the other ones I mentioned are rated at 240V; NEMA 5-15 outlets are typically wired to either 15A or 20A circuit breakers (for the latter, a 5-15 plug outlet rated at 20A must be used), NEMA 14-30 outlets need to be wired to a minimum 30A breaker, and NEMA 14-50 must be wired to a minimum 50A breaker.
It should also be pointed out that if choosing to run wire from a 60A breaker the wire gauge used here is somewhat thicker than that used to run wire from a 50A breaker--meaning, more expensive per foot; you many want to keep that in mind if you don't have a 60A breaker already in place and are looking to have one installed. Do not try to be cheap and cheat your way around it--electrical code requires it plus it's not worth the risk of potentially having your home burn down. If looking to power a home EVSE off a 60A circuit it is highly recommended to hardwire said EVSE to the 60A circuit rather than plugging it into a receptacle capable of handling 60A.
As far as current draw itself goes--electrical code requires that the max current draw cannot exceed 80% of the circuit breaker's rating--meaning, for a 60A breaker the max draw is 48A, 50A breaker is 40A, 30A breaker is 24A, 20A breaker is 16A, and 15A breaker is 12A. What does this mean in terms of power draw? Given that W(atts) = V(olts) * A(mps), and the voltage rating of the various NEMA plugs I mentioned above, you get this (and yes I realize this is explained on the Tesla wall connector product page as well):
NEMA 5-15 -> 120V * 12A = 1.44 kW
NEMA 6-20 -> 240V * 16A = 3.84 kW
NEMA 14-30 -> 240V * 24A = 5.76 kW
NEMA 14-50 -> 240V * 40A = 9.6 kW
NEMA 60A -> 240V * 48A = 11.52 kW
It should be pointed out that currently there aren't that many EV models that can charge at rates higher than 11 kW so unless your home already has a 60A breaker (and an outlet wired into the 60A circuit) already in place and/or you have a Tesla and really need the Tesla wall charger's 48A capabilities it makes little sense to spend money to have one installed. Your typical public charging stations are capable of charging at much higher kW rates because they use DC charging vs. AC charging (which is applicable to the stuff I mentioned above).
I'm not gonna debate as to whether one really needs to charge at higher rates when charging at home and/or its effects on long-term battery health, just simply throwing out the raw numbers here for those wondering about charging times; you can do the math by looking at the various power draws I listed above and knowing the battery capacity of your EV in order to then determine how long it will take to charge your vehicle based on your EVSE's capabilities and home electrical setup.
Every other modern Tesla can charge at 48 amps, which the Wall Connector can supply.
A mobile connector + 14-50 adapter costs $320 anyways, this isn't much more unless you're okay not carrying the mobile connector.

NEMA 14-50 is an electric plug, so yes, technically you can plug any appliance that uses that socket, including Samsung and LG dryers. What's your point? 48 amp vs 32 amp = 50% faster. It won't benefit you if you have the standard range model 3, as alluded to above. Now only you can decide if 50% charger rate is worth it. Don't make sweeping statements like that.

FYI the 30% EV charging tax credit also applies to this, making it $347. A mobile connector + 14-50 adapter costs $320. So unless you're okay with not having a mobile connector in your car, you don't really save any money.
