Rivian Wall Charger Installation in New Hampshire

The Rivian Wall Charger is the home Level 2 charging unit for Rivian R1T and R1S electric vehicles. Rivian sells two versions: a J1772 model for 2022-2025 vehicles and a NACS model for 2026 and newer vehicles, which come with native NACS charge ports. Installed correctly on a properly sized circuit, either version delivers up to 11.5 kW on a 240-volt 60-amp circuit, which restores roughly 25 miles of range per hour. For southern New Hampshire Rivian owners, a professional installation handles the electrical work, NEC code compliance, permitting, and inspections in one visit.

At A.J. LeBlanc Heating, our licensed electricians install EV chargers across NH. Here is what a Rivian Wall Charger installation actually involves.

Rivian Wall Charger specifications

Rivian sells two wall chargers with the same electrical specs; the difference is the connector and the model years each matches.

Maximum output: 48 amps continuous on a 60-amp circuit, equal to 11.5 kW
Voltage: 240V single-phase
Connector (J1772 version): SAE J1772, for 2022-2025 R1T and R1S vehicles; also compatible with most other non-Tesla EVs
Connector (NACS version): NACS, for 2026 and newer Rivian vehicles, which have native NACS charge ports and use J1772 equipment only through an adapter
Cable length: 24 feet
Mounting: indoor or outdoor (weatherproof enclosure)
Connectivity: Wi-Fi for app integration, scheduling, and software updates
Network features: integrates with the Rivian app for charge scheduling, energy use tracking, and home electricity management

What a complete installation includes

A proper Rivian Wall Charger install in a NH home includes:

Site assessment and load calculation

Before any equipment is ordered, our electrician evaluates:

Your electrical service capacity (most NH homes have 100A or 200A service)
Available space at the main panel for a new 60A breaker
The route from the panel to the proposed charger location
Whether your existing service can accommodate an additional 60A continuous load (NEC Section 220 load calculation)
The right location for the charger itself (proximity to where the vehicle parks, weather exposure, accessibility)

For homes that cannot accommodate the full 60A circuit because of service limitations, the Rivian Wall Charger can be configured for lower amperages (40A, 32A, or 16A) during commissioning. Lower amperage means slower charging but allows installation in homes with limited capacity.

Electrical work

Install a new 60-amp double-pole breaker in the main panel
Run appropriately sized conductors (6 AWG copper for a 60A circuit, larger for long runs)
Install the disconnect if required by local code
Comply with NEC Section 625 (electric vehicle power transfer system requirements)
Use a dedicated circuit that serves only the charger (NEC requirement)

Charger mounting and connection

Mount the unit at the proper height (typically 4 feet off the ground)
Terminate the conductors to the charger
For outdoor installations, ensure proper weatherproof entry and seal

Permits and inspection

NH municipalities require electrical permits for EV charger installations. We pull the permit, schedule the inspection, and coordinate with the local building department.

Commissioning and owner orientation

Energize the circuit and verify proper operation
Configure the charger output amperage to match the installed circuit
Walk through Wi-Fi setup and Rivian app pairing
Cover safe operation, the charger's status indicators, and what to do if there is an issue

NEC code compliance basics

The National Electrical Code (NEC) governs EV charger installations. Key requirements:

Dedicated circuit (no other loads on the same breaker)
Continuous load rated at 125 percent (a 48A charger requires a 60A breaker)
GFCI protection on the circuit (some jurisdictions; charger has internal protection)
Service load calculation to confirm the home's electrical service can support the new load
Proper conductor sizing per NEC Article 310

Skipping these requirements creates a fire and electrical safety risk and will fail inspection.

Incentives

Incentive programs for EV charger installations come and go. Ask us what currently applies before you schedule.

Some NH utilities also offer rebates or special EV time-of-use rates that benefit home charging. Check with your utility for current programs.

Why use a licensed electrician

EV chargers draw the largest continuous load most homes have ever added: 48 amps continuous over many hours at a time. Improper installation can:

Overload the home's electrical service
Trip breakers repeatedly
Damage the charger or vehicle
Create fire risk from undersized conductors or improper terminations
Fail inspection and require expensive rework
Void manufacturer warranties

DIY EV charger installation is one of the most common reasons we get called to fix electrical problems after the fact.

Frequently Asked Questions

How fast does the Rivian Wall Charger charge?

Up to 11.5 kW on a properly installed 60A circuit, which restores roughly 25 miles of range per hour in an R1T. Charging speed scales down with lower-amperage circuits.

Which Rivian Wall Charger do I need?

Rivian vehicles from 2022-2025 have a J1772 charge port and match the J1772 wall charger. Rivian vehicles from 2026 on have a native NACS port and match the NACS wall charger; they can use J1772 chargers only through an adapter.

Can I install the Rivian Wall Charger on a 50-amp circuit?

Yes. The charger can be configured during commissioning for 40A output on a 50A circuit, which still delivers about 9.6 kW of charging power. Useful when full 60A capacity is not available.

Does my NH home have enough electrical capacity?

Most NH homes with 200A service can support a 60A EV charger circuit. Homes with 100A service usually require a service upgrade or load management. Our electrician runs a Section 220 load calculation as part of the install assessment.

Do I need a permit for an EV charger?

Yes. Electrical permits and municipal inspections are required for EV charger installations in NH. We handle permits as part of a complete installation.
