About tesla wall connector installation
The Wall Connector is hardwired rather than plugged into an outlet, and its output is set during installation to match the circuit: up to 48 amps on a 60 amp breaker, or lower on smaller circuits. EV charging is a continuous load, so circuits are sized at 125% of the charging current.
Many older homes cannot add a 60 amp circuit without a panel upgrade. A lower charging setting, or load sharing between two Wall Connectors, are common ways to fit within an existing service.

Tesla Wall Connector Installation FAQ
What breaker does a Tesla Wall Connector need?
Up to a 60 amp breaker for the maximum 48 amp output; smaller breakers are allowed with a lower current setting.
Can I use a NEMA 14-50 outlet instead?
Yes, with Tesla's mobile connector, but output is lower than a hardwired Wall Connector at full power.
Can two Wall Connectors share one circuit?
They can share power across units through Tesla's power-sharing feature, which helps homes with limited capacity.
Does a Wall Connector work with other EVs?
Newer versions with the J1772 connector work with most EVs; the NACS version needs an adapter for some vehicles.
Do I need a permit?
Yes in most places, because it adds a new 240-volt circuit.
