Having a Tesla Wall Connector put in on Long Island usually comes to about $900 to $1,800 with the charger included, as long as the panel can take the extra circuit. A long run to a detached garage or a panel upgrade pushes past that.
The Wall Connector job, priced by Long Island installers
| Piece of the job | Price | Source |
|---|---|---|
| Typical install, charger, wiring, labor and permit included | $900 to $1,800 | StandTech Electric, Port Washington |
| Wall Connector unit | $500 to $600 | Haines Electric, Lido Beach, 2025 |
| Wall Connector unit | about $475 | Marra Electric, Bohemia, Dec 2025 |
| Labor and materials | $800 to $2,000 | Haines Electric, 2025 |
| Electrical permit and inspections | $150 to $400 | Haines Electric, 2025 |
| Circuit upgrades, if needed | $500 to $2,000 and up | Haines Electric, 2025 |
StandTech prices major panel upgrades separately and says it quotes them before the work starts.
Breaker size and charging speed, from Tesla’s manual
Tesla’s Gen 3 Wall Connector installation manual ties the output to the breaker it sits on:
| Breaker | Charging current | Power at 240 volts |
|---|---|---|
| 60 amps | 48 amps | 11.5 kW |
| 50 amps | 40 amps | 9.6 kW |
| 40 amps | 32 amps | 7.6 kW |
| 30 amps | 24 amps | 5.7 kW |
| 20 amps | 16 amps | 3.8 kW |
| 15 amps | 12 amps | 2.8 kW |
For full power the manual calls for at least 6 AWG copper rated at 90°C, and the terminals take copper only. Each Wall Connector gets its own branch circuit. A house that cannot spare 60 amps can still run one on a 40 or 50 amp breaker and charge more slowly.
In range terms, StandTech Electric says a Wall Connector adds up to 44 miles per hour of charging, while a NEMA 14-50 outlet tops out at 32 amps and around 30 miles per hour.
Details in the manual that change the quote
- No GFCI breaker. GFCI protection is built into the unit, and Tesla says not to add a GFCI breaker. An outside disconnect switch is neither required nor recommended.
- Outdoor mounting is fine. The enclosure is rated Type 3R. Outdoor installs need watertight fittings and the sealing gaskets in place.
- The breaker size is set at setup. The installer joins the unit’s own Wi-Fi network, opens its setup page and enters the breaker size, then connects it to your home Wi-Fi. Green lights on the unit show the maximum it was set to.
Ask the electrician to show you the setting before leaving. A Wall Connector on a 60 amp breaker but set for less will charge at the lower rate.
A Tesla and another EV in the same garage
Marra Electric notes that the standard Wall Connector only works with Teslas unless you use an adapter. Tesla’s Universal Wall Connector has a built-in adapter that switches between Tesla’s NACS plug and the J1772 plug most other EVs have used, and Marra says several Universal units can share one circuit by talking to each other wirelessly. If the second car in the driveway is not a Tesla, price the Universal model.
The PSEG rebate and a Wall Connector
PSEG Long Island’s $100 Level 2 rebate, or $400 for qualifying households, applies only to chargers on the EPRI Vetted Products List for PSEG Long Island, installed by a participating contractor. Check the exact Wall Connector model against that list before buying. The EV charger page covers how to apply and PSEG’s Time of Day rate.
Ask the installer
- What breaker size can my panel spare, and what charging current does that give me?
- Is the permit and inspection included, and which inspection agency will you use?
- Where will the unit mount, and how long is the run from the panel?
- Will you finish the Wi-Fi setup and show me the current it is set to?
- Are you on PSEG Long Island’s participating installer list?
Haines Electric says Tesla strongly recommends a licensed electrician for the install, and Tesla’s manual says the unit should only be installed by people trained and qualified to work on electrical systems.
