Tesla home charger install.

Every modern Tesla — Model 3, Y, S, X, and Cybertruck — has an onboard charger capped at 48A. The right install is a hardwired 48A Tesla Wall Connector on a dedicated 60A circuit. Network installers are Tesla-approved, which means the warranty stays valid. Most Tesla installs in our service area are $1,290–$1,800 on existing 200A panels, 3–5 hours, no panel upgrade required.

Tesla-specific install considerations

Common Tesla install scenarios

"I just bought a Model Y and want a Wall Connector."

Standard install. 200A panel, dedicated 60A breaker, hardwired Wall Connector, WiFi pairing tested. $1,290–$1,800 typical. 3–5 hours on site.

"My panel is 100A and I want a Wall Connector."

Network installer will recommend one of three paths:

"I have two Teslas."

Tesla Power Sharing. Install two Wall Connectors on a shared 60A circuit. They negotiate — one charges at full rate when the other isn't, both step down when both plug in. $2,400–$3,000 for the second connector if installed alongside the first.

"I want to use the Mobile Connector instead."

Install a NEMA 14-50 outlet. Caps at 32A per NEC continuous-load rule. $680–$1,400. Slower than hardwired but portable. Tesla doesn't void the car's warranty if you use the Mobile Connector exclusively, but the Wall Connector's own warranty doesn't apply.

One Tesla, fits-without-upgrade math: a 100A panel + Tesla + 32A install ≈ no upgrade needed. A 125A panel + Tesla + 48A install ≈ usually fits. A 200A panel + Tesla + 48A install ≈ always fits. The free panel check determines this with NEC 220 demand math.
