Rivian radically shifted the electric vehicle paradigm with the introduction of the R1T pickup truck and the family-hauling R1S SUV. These are not compact commuter sedans; they are massive, heavy, off-road capable adventure vehicles. Consequently, they house exceptionally large battery packs—often exceeding 135 kWh or even 149 kWh in the "Max Pack" configurations.
In order to recharge a battery that large overnight—especially after returning from a weekend towing a boat to Lake Powell or traversing back roads in Moab—standard trickle charging is entirely fundamentally useless. You must have the ability to pump serious amperage into the vehicle. This is where Paulsen Power enters the equation, providing expert installation of the Rivian Wall Charger directly into your home's electrical ecosystem.
The official Rivian Wall Charger is a beautiful, weather-proof, Wi-Fi-enabled Level 2 charging system. When properly hardwired by our master electricians, it provides:
To reach the 11.5 kW output ceiling, the Rivian Wall Charger must provide a continuous current of 48 amps. According to the National Electrical Code formulation rules for continuous loads, the breaker and circuit must be rated 25% higher than the continuous draw. This means the charger must be hardwired directly into a dedicated 60-Amp 240V circuit.
Unlike portable "dryer plugs" (NEMA 14-50 and 6-50 receptacles) which limit the overall system cap to 40 amps of continuous draw, hardwiring eliminates the physical connector bottleneck. Receptacles inherently suffer from wear and tear over thousands of insertion and removal cycles, which increases resistance. High resistance during long-duration 240V charging creates immense heat, eventually leading to melted plugs or house fires. Hardwiring thick-gauge copper directly into the internal terminal blocks of the Rivian charger provides bulletproof, thermal-rated reliability.
A 60-amp circuit is essentially identical in scale to the wiring needed to run an entire 3-ton central HVAC system, or a massive double wall oven. When Paulsen Power approaches a Rivian charger installation, our first task is a comprehensive load calculation.
Many older homes in Utah simply do not have the panel capacity to support adding a 60-amp breaker. If a home only has 100 amps or 125 amps of total incoming capacity from Rocky Mountain Power, pulling almost half of that to charge a vehicle at 2 AM while the heat pump is running will unequivocally trip the main terminal breaker.
If your panel lacks capacity, Paulsen Power provides seamless Panel Upgrades (usually heavy-ups to a 200 Amp or 400 Amp service). We coordinate the entire process with the city inspector and the power company, establishing the foundation needed before we pull the 4 AWG copper wire to fuel your Rivian.
Because Rivian vehicles are explicitly designed for the outdoors, many owners lack the garage space to park an R1T fully enclosed while the bed is loaded with gear. They need the charger mounted outside on a post or directly attached to the exterior brick.
The Rivian Wall Charger is NEMA Type 4 rated, meaning it is totally shielded against wind-blown dust and torrential rain. However, the conduit supplying power to the unit must also be outdoor-proof. Our technicians use specialized liquid-tight PVC outer conduit and rigid galvanized steel masts when running wire on exterior surfaces, ensuring water never penetrates the junction points, regardless of heavy snowfall or brutal summer heat.
Currently, the Rivian Wall Charger utilizes the J1772 connector, which is the universal standard for virtually all non-Tesla EVs in North America (though they are transitioning to the NACS port moving forward). This means a J1772 Rivian charger can also easily charge a Ford Lightning, a Chevy Bolt, or a Porsche Taycan without any adapters.
Using the portable charger that comes with a Rivian in a standard 120V outlet (Level 1) will typically provide less than 2 miles of range per hour. Since the truck's battery is massive, replenishing a dead battery on Level 1 charging could literally take four days. You absolutely need a 240V Level 2 solution for daily driving.
Since the unit is hardwired, we do not recommend homeowners try taking it down themselves. Because you are dealing with live 240V mains, a dedicated electrician must disconnect the unit safely and place the circuit within an isolated junction box. However, leaving the high-capacity charger is often a major selling point that increases the appraised value of the home.
Don't let inadequate electrical wiring bottleneck your adventures. Allow Paulsen Power to design and implement a world-class charging structure to support your Rivian R1T or R1S. We proudly serve homeowners across the state of Utah with uncompromising precision.
