Rivian Wall Charger Installation in New Hampshire
Rivian publishes a NACS Wall Charger for 2026 and newer Rivian vehicles with up to 48 amps or 11.5 kW on a properly designed 60-amp circuit. Rivian lists up to 25 miles of range per hour for R1S and R1T under optimal conditions. Actual charging speed varies with the vehicle, circuit setting, battery, temperature, and site conditions. A.J. LeBlanc Heating's licensed electricians confirm the vehicle and connector before equipment is ordered.

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:
- Service rating, existing calculated load, panel condition, available spaces, other large loads, charging needs, and approved load management
- 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
A licensed electrician performs the service and load calculation, selects conductors and overcurrent protection for the actual route and installation method, confirms current code and manufacturer instructions, and determines permit and inspection requirements with the local authority having jurisdiction.
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
Permit and inspection requirements are confirmed with the local authority having jurisdiction. When required for our scope, we coordinate the permit and inspection.
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?
Rivian lists up to 25 miles of range per hour for R1S and R1T under optimal conditions. Actual charging speed varies with the vehicle, circuit setting, battery, temperature, and site conditions.
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?
Service rating alone does not determine available charging capacity. Existing calculated load, panel condition, available spaces, other large loads, charging needs, and approved load management all matter.
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.
