Does a Model Y take 32 amps or 48 amps?
Tesla's pages disagree. Its onboard charger table lists "Model Y" at 48 amps (11.5 kW) with a 60 amp breaker, with no split by version. Its home charging FAQ says Model Y Rear-Wheel Drive tops out at 32 amps, on a 40 amp breaker. The reliable answer is on the car: tap the lightning bolt icon on the touchscreen to see its maximum amperage.
| Tesla document | What it says about Model Y |
|---|---|
| Onboard Charger support page | Model Y: 11.5 kW (48 amp), 60 amp breaker for a Wall Connector |
| Home Charging support page, FAQ | Model Y Rear-Wheel Drive: 32 amp maximum, Wall Connector on a 40 amp breaker or Mobile Connector on a NEMA 14-50 |
| 2020-2024 Model Y service manual | "Model Y accepts up to 48A when equipped with the Long Range Battery" |
tesla.com blocks automated checks, so the two support pages were read through Internet Archive captures from April and May 2026; the FAQ wording is the same in captures back to April 2025. The service manual was read on service.tesla.com.
Tesla's July 2026 Model Y page sells Standard (rear- and all-wheel drive), Premium (rear- and all-wheel drive), Performance and the longer Model Y L. Its spec tables give Supercharging peaks but no home charging rate, so read the maximum amps from the car's touchscreen before sizing the circuit. A used Model Y needs the same screen check.
Which circuit should a Model Y get?
If the screen shows 48 amps, a hardwired Wall Connector on a 60 amp breaker is the setup that uses it. If it shows 32 amps, Tesla says a Wall Connector on a 40 amp breaker or a Mobile Connector on a NEMA 14-50 outlet gives the same top speed. If you are unsure, or a second EV is likely, the 60 amp circuit covers both.
| Setup | Breaker | Fits |
|---|---|---|
| Wall Connector, hardwired | 60 A | 48 amp Model Y at full speed; a 32 amp car simply draws 32 |
| Wall Connector, hardwired | 40 A | 32 amp Model Y at full speed, smaller load on the panel |
| NEMA 14-50 with Mobile Connector | 50 A GFCI | 32 amp Model Y at full speed; 48 amp car limited to 32 |
A Wall Connector's output is set from the breaker size the installer enters during commissioning in Tesla's installer app, so one unit can serve either version. The 125 percent rule behind these pairings is in our guide to what size breaker an EV charger needs, and Level 2 EV charger installation covers the wiring.
For the outlet route, Tesla's current Mobile Connector bundle ships with NEMA 5-15 and NEMA 14-50 adapters. Under NEC 625.54 the 14-50 needs GFCI protection when it is installed for EV charging, which Utah keeps even though it relaxed the general garage rule for 240 volt receptacles. More on that choice in home EV charger installation.
How fast does a Model Y charge at home?
Tesla gives home charging speed in miles of range per hour: 2 to 3 on a 120 volt outlet, up to 30 on a 32 amp 240 volt connection, and up to 44 on a Wall Connector for cars that accept 48 amps. Tesla does not publish usable battery capacity or full-charge hours for the Model Y in the documents we read.
For most commutes, the gap between 30 and 44 miles per hour matters less than it looks, because the car refills overnight either way. It matters after a long trip, or in a household where the car is out late and needs to leave early.
Where should the charger go for a Model Y?
Plan the mount around the charge port, which Tesla's manual places on the left side of the car in the rear tail light assembly. Whether you back in or pull in nose first changes where that corner sits, so decide how the car will park before choosing the wall. The Wall Connector's cable is 24 feet; the Mobile Connector's is 20.
In a two-car garage, the bay the Model Y uses matters. A charger on the far wall from the Model Y's bay can leave the cable lying across the other car's path every night. Settle which car parks where before the installer picks the wall.
What about Model Y charging in Ogden winters?
Tesla's manual warns that the charge port latch can freeze in icy conditions. Some cars have a charge port inlet heater that runs with the rear defrost, and Controls, Service, Inlet Heater warms a stuck connector for up to two hours. Scheduled preconditioning before you leave helps prevent freezing in the first place.
Tesla also "strongly recommends" leaving the car plugged in when parked, and the manual notes that a plugged-in car runs its systems from the charger rather than the battery. For a driveway charger, both Tesla Wall Connectors carry a Type 3R rating and a -22°F operating floor; see the Tesla Wall Connector guide for the details.
What if the Model Y shares the garage with another EV?
For two Teslas, Tesla recommends two Wall Connectors configured for Group Power Management, which share the site's available power over Wi-Fi. If the second car has a J1772 port, make one unit a Universal Wall Connector. Either way, the panel only has to carry the shared limit, not two full 48 amp loads.
NEC 220.70 lets an energy management system's setpoint count in the load calculation, which is the code basis for that sharing. See EV charger load management and the Tesla home charging overview for the rest of the lineup. If the panel is tight, we check whether load management solves it before talking about an upgrade.
Tesla Model Y home charging questions
Does a Model Y charge at 32 amps or 48 amps?
It depends on the car, and Tesla's own pages differ. Tesla's onboard charger table lists Model Y at 48 amps (11.5 kW) on a 60 amp breaker. Tesla's home charging FAQ says Model Y Rear-Wheel Drive charges at a 32 amp maximum. Tap the lightning bolt icon on the touchscreen to see your car's maximum amperage before sizing a circuit.
Can I just use a NEMA 14-50 outlet for my Model Y?
Yes. Tesla's Mobile Connector draws 32 amps on its NEMA 14-50 adapter, which is the full rate for a 32 amp Model Y and two thirds of the rate for a 48 amp car. In Utah, a receptacle installed for EV charging needs GFCI protection. A hardwired Wall Connector on a 60 amp breaker is the only way to reach 48 amps.
Where should the charger go for a Model Y?
Near the left rear of where the car parks. The owner's manual puts the charge port on the left side, in the rear tail light assembly. The Wall Connector's 24 foot cable and the Mobile Connector's 20 foot cable give some slack, but a charger on the wrong side of a two-car garage can leave the cable stretched across the floor.
What if my Model Y charge port freezes?
Tesla's manual says the charge port latch can freeze in icy weather. Some vehicles have a charge port inlet heater that runs with the rear defrost, and Controls, Service, Inlet Heater warms a stuck connector for up to two hours. Scheduling preconditioning before departure also helps prevent it.
Can a Model Y share a charger with a non-Tesla EV?
Yes, with the Universal Wall Connector, which has a docked J1772 adapter for other EVs. The standard Wall Connector and Mobile Connector have NACS plugs that Tesla says only work with Tesla vehicles. For two EVs charging at once, Tesla recommends two Wall Connectors set up for Group Power Management.
