Tesla Wall Connector spec sheet: every number an installer or owner needs

Tesla wall connector specs for the US unit in one line: 200 to 240 V single-phase, 12 to 48 A output (up to 11.5 kW), a 60 A breaker for full power, a 24 ft cable, 13.6 x 6.1 x 4.3 in, 10 lb, and a Type 3R / IP54 enclosure. Everything below expands on that, with the source for each figure.

One warning before the tables. Most "Tesla Wall Connector datasheet" PDFs online are the European version: 230/400 V, 32 A, up to 22 kW on three-phase, IP55, Type 2 plug. None of those numbers apply to a US garage. This page uses the North American installation manual (part number 1457768-xx-x) unless it says otherwise.

Full Gen 3 specification table (North America)

A note on weight: the current North American manual says 10 lb with the wirebox, while Tesla's 2021 one-page datasheet lists 15 lb (6.8 kg) including the bracket. We use the manual figure because it is the newer document and the one installers work from. If you are planning a wall anchor, 15 lb is the safe number to design for.

Breaker size, output and charging speed

The Gen 3 has no rotary switch. The installer selects the breaker size in the Tesla One app during commissioning, and the unit caps its output at 80% of that breaker, which is the NEC 625.41 rule that EV chargers count as continuous loads protected at 125% of their rating (48 A x 1.25 = 60 A).

Model 3 and Model Y:

Model S, Model X and Cybertruck:

Model columns are miles of range added per hour, from Tesla's support page. Cybertruck figures are for the Premium AWD. Tesla's manual lists the 32 A row as 7.6 kW and the support page as 7.7 kW; 32 x 240 = 7,680 W, so either rounding is fair.

The table has one large footnote. Base Model 3 and base Model Y trims accept only 32 A (7.7 kW, about 30 mi per hour) however big the breaker is. Long Range, Premium and Performance trims, the Model S, Model X and Cybertruck take the full 48 A. Tap the lightning bolt on the car's touchscreen to see its limit before you pay for a 60 A circuit. Our amps and breakers guide goes deeper on choosing a setting.

A worked example

A Model Y Premium on a 60 A circuit, plugged in from 11 pm to 6 am:

• Power at the wall: 48 A x 240 V = 11,520 W, or 11.5 kW.
• Energy in 7 hours: 11.5 x 7 = 80.5 kWh drawn from the panel.
• Range added at Tesla's 44 mi per hour: 44 x 7 = 308 miles.

Most cars never need anything like that on a weeknight. The extra power matters on the night before a road trip, or when two cars share one circuit. For full-charge times by battery size, see how long it takes to charge a Tesla.

Wire, conduit and circuit requirements

These are Tesla's requirements from the North American manual. Local code and the inspector (the authority having jurisdiction, or AHJ) can add to them, and a licensed electrician should size the circuit and pull the permit.

• Copper only. The terminals are marked "copper wire terminations only"; stranded or solid is fine.
• Full power with a 75 C-rated breaker: minimum 6 AWG copper, 90 C THWN-2.
• Full power with a 60 C-rated breaker: minimum 4 AWG copper, 90 C THWN-2.
• Below full power: conductors and ground sized to local code for the breaker you choose. Tesla gives no per-breaker gauge table.
• Terminal range: 12 to 4 AWG copper.
• Conduit entry: 3/4 in by default, 1 in optional.
• Dedicated circuit: NEC 625.40 requires an individual branch circuit for EV equipment over 16 A, except where an approved energy management system shares capacity.
• No neutral, but a ground: two hots plus an equipment grounding conductor. One supply leg must be bonded to ground (normally the neutral-ground bond at the main panel) for the ground assurance check to pass.
• No plug: the Gen 3 must be hardwired. Tesla's manual prohibits cord-and-plug connections.

Electricians commonly pair breakers and copper conductors like this at 75 C terminations: 12 AWG for 15 or 20 A, 10 AWG for 30 A, 8 AWG for 40 A, 6 AWG for 50 or 60 A. That is general NEC practice, not a Tesla specification, and run length, conduit fill and the wiring method can change the answer. One point electricians argue about is whether 6 AWG NM-B cable (rated 55 A at 60 C) can feed a 60 A breaker for a 48 A charger. Tesla's own answer is 4 AWG when the termination rating is 60 C, so this is a decision to leave to your electrician and inspector. Our guide to mounting and wiring the unit covers the rest of the job.

Gen 3 vs Universal Wall Connector vs Gen 2 specs

Tesla's own documents disagree on a few Universal figures (weight and the safety listing in particular), so both are shown. The Universal datasheet also lists UL 2594 and UL 2231 standards and Energy Star certification. For which one to buy, see our Wall Connector vs Universal comparison; for identifying and living with an older unit, see our Gen 2 and Gen 3 comparison.

Network and power management specs

The Gen 3 joins only 2.4 GHz networks using 802.11b/g/n, and Tesla requires WPA2-CCMP/AES security with no captive portal. Guest isolation and MAC filtering may need to be switched off. Firmware 26.2.0, rolled out from February 2026, reportedly fixed drop-outs on mixed WPA2/WPA3 routers. If yours will not connect, our Wi-Fi troubleshooting guide covers the router side.

Three power management modes exist, and all work without internet once configured:

For dynamic mode the installer sets a "Max Conductor Limit" of about 80% of the panel rating. Gen 2 units cannot join a Gen 3 sharing group.

What the spec sheet leaves out

A few things matter in practice that no datasheet prints:

• The car sets the ceiling. A 48 A Wall Connector on a base Model 3 delivers 32 A. Check the car before sizing the circuit.
• 208 V buildings charge slower. Many condos and commercial garages supply 208 V. At 48 A that is about 10 kW (48 x 208 = 9,984 W), roughly 13% less than at 240 V. The same applies to Tesla destination charging at hotels.
• Level 2 is efficient but not lossless. Studies summarized by Recurrent put 240 V charging at roughly 89% to 95% efficient, so expect the meter to read a little more than the car's charging screen.
• The cable is the limit on reach, not the circuit. 24 ft covers most single-car garages from a side wall. Measure from the planned mounting point to the car's charge port (rear left on Model 3, Y, S and X) with the car parked the way you actually park.
• A plug-in option exists, but not with a Gen 3. If you want a receptacle instead of a hardwired unit, compare NEMA 14-50 receptacle setups, including the GFCI rule for garage receptacles.

Download the Tesla Wall Connector spec sheet PDF, updated October 13, 2026. It prints the four reference sections from this page on three Letter pages: the Gen 3 specification table, the breaker and miles-per-hour tables, Tesla's wire and circuit requirements, and the Gen 3 vs Universal vs Gen 2 comparison. Every figure in it is the North American one. For the installation itself, work from Tesla's North American installation manual, and for the Universal model, Tesla's Universal Wall Connector datasheet.
