About the RAB EVC48/LCB
The RAB EVC48/LCB is a 16 A dual-input Level 1/Level 2 EV charger (electric vehicle supply equipment, or EVSE) certified under the ENERGY STAR program. It delivers up to 16 A at 120 V, a maximum of 1.92 kW.
At full output that adds roughly 6–8 miles of driving range per hour of charging, assuming a typical EV efficiency of 3–4 miles per kWh. The vehicle's onboard charger sets the real limit: a car that accepts less AC power than the charger can supply will charge at its own maximum rate.
It is network capable over Wi-Fi/Ethernet, other LAN, or cellular. Equipment includes an RFID card reader and an ISO 15118 power-line communication board.
With no vehicle connected it draws 2.75 W of standby power. That standby figure is lower than 66% of the 30 Dual Input (Level 1/2) models in our database.

Safety information
- Have a licensed electrician install any hardwired charger and any new circuit or receptacle for EV charging. Most jurisdictions require an electrical permit and inspection.
- EV charging equipment must be installed in accordance with the National Electrical Code (NEC Article 625) or the Canadian Electrical Code and local amendments. EV charging is a continuous load, so the branch circuit must be rated for at least 125% of the charger's maximum current.
- Never use an extension cord, plug adapter or multi-outlet strip with an EV charger, and do not plug a portable charger into a worn or loose receptacle — these are leading causes of overheating and fires.
- Do not use the charger if the cable, connector or enclosure is cracked, crushed or shows exposed conductors. Take it out of service and contact the manufacturer or an electrician.
- Keep the connector in its holster when not in use and route the cable so it cannot be driven over or become a tripping hazard.
- Do not open the charger enclosure; there are no user-serviceable parts inside and dangerous voltages may be present even when it is not charging.
Installation and first-time setup
As a dual-input unit, this charger can run from either a 120 V or a 240 V supply. At 120 V it draws up to 16 A (1.92 kW). Because charging runs for hours at a time, plug it into a receptacle on a circuit rated at least 20 A (125% of 16 A), ideally a dedicated circuit with nothing else on it.
- Have an electrician check the receptacle and its wiring before relying on it for nightly charging; an older or worn receptacle can overheat under a long continuous load.
- Codes based on the 2020 NEC and later require GFCI protection for receptacles installed for EV charging, and outdoor receptacles need a weatherproof "in-use" cover.
- For 240 V (Level 2) use, a dedicated 240 V circuit and receptacle matching the unit's plug or adapter are required; follow the manual for the current rating at 240 V and size the circuit at 125% of it.
Network setup
Confirm a strong Wi-Fi signal (or run Ethernet, where supported) at the mounting location before installation — garages and outdoor walls are often weak spots. Register the charger in the manufacturer's app to enable scheduling, energy reports and firmware updates.
Using your EV charger
Starting and stopping a charge
- Park so the charge port is within reach of the cable without strain.
- Authorize the session if required — tap an RFID card or start it from the app.
- Insert the connector fully into the vehicle's port until it latches. The charger checks the connection and ground before it energizes the cable.
- Charging starts automatically unless the vehicle or charger has a schedule set. Check the vehicle display or charger indicator to confirm.
- To finish, end the session from the vehicle or app (or simply unlock the vehicle), press the connector release button, remove the connector and return it to its holster.
How long charging takes
| Energy added | Approximate range | Time at 1.92 kW |
|---|---|---|
| 10 kWh | about 30–40 miles | about 5 h 45 min |
| 20 kWh | about 60–80 miles | about 11 h 35 min |
| 30 kWh | about 90–120 miles | about 17 h 20 min |
Scheduling and smart charging
Use the app or the vehicle's own scheduler to charge during off-peak hours if your utility offers a time-of-use rate — set the schedule in one place only, because two competing schedules are a common reason a car does not charge.
ISO 15118 communication
The ISO 15118 power-line communication board allows richer data exchange with compatible vehicles, which is the basis for features such as Plug & Charge authorization. Whether these features work depends on the vehicle, the charger firmware and the network operator.
Cable care during use
The 16 ft cable should hang or lie without kinks. Do not wrap it tightly around the unit, pull the vehicle forward while connected, or leave the connector lying in water or snow. In freezing weather, clear ice from the connector before inserting it.
Care and maintenance
| When | What to do |
|---|---|
| Every month | Inspect the cable and connector for cuts, crushing, bent pins or a damaged latch. Keep the connector and holster free of dirt, leaves and insects. |
| Every 3 months | Wipe the enclosure and cable with a damp cloth (power off for cleaning beyond a light wipe). Do not pressure-wash the unit or spray water into the connector. |
| Every 6 months | Inspect the plug blades and the receptacle for discoloration or looseness, and check the cable strain reliefs at both ends of the control box. |
| Every year | Have an electrician check the circuit connections and, for plug-in units, the receptacle for heat discoloration or looseness. |
| As released | Install firmware updates through the app or network platform; they can add features and fix charging or connectivity faults. |
| Every month (public sites) | Clean the display and card-reader faces and confirm payment and authorization work. |
Troubleshooting
Most charging problems come from schedules, connector latching or the vehicle's own settings. Work through these checks before calling for service.
| Problem | Possible cause | What to try |
|---|---|---|
| Vehicle will not start charging | Connector not fully latched; a charging schedule is set in the car or app; vehicle already at its charge limit. | Reinsert the connector until it clicks; check both the vehicle and charger schedules; confirm the vehicle's charge-limit setting. |
| Charger has no power or lights | Breaker tripped or switched off; GFCI tripped (plug-in units). | Check and reset the breaker or GFCI once. If it trips again, stop and call an electrician. |
| Charging is slower than expected | Vehicle onboard charger limit; current limit set below 16 A; cold or nearly full battery. | Check the vehicle's maximum AC charging rate; confirm the installer's current setting; charging naturally slows as the battery approaches full. |
| Charging stops partway through | Ground-fault or over-temperature protection activated; utility or app schedule ended the session. | Note any fault light pattern and look it up in the manual's fault table; check the session history in the app. |
| Ground-fault or fault indicator lit | Moisture in the connector; damaged cable; vehicle-side fault; wiring issue. | Dry the connector, try again, and test with another vehicle if possible. Repeated faults need an electrician or the manufacturer. |
| Connector will not release | Vehicle has locked the connector. | Unlock the vehicle or end the session from the vehicle; most EVs have a manual release described in the owner's manual. |
| Charger shows offline in the app | Weak Wi-Fi or cellular signal; changed router password; network outage. | Move the router or add an access point; re-run network setup; the charger normally still charges locally while offline. |
| Error code displayed | Brand-specific diagnostic code. | Error codes are not standardized; consult the code table in your manufacturer's manual or app before calling support. |
Energy use and running costs
ENERGY STAR certification for chargers focuses on the power the equipment itself consumes. With no vehicle connected, the RAB EVC48/LCB draws 2.75 W. Even if it sat in that mode around the clock, that would add up to about 24 kWh a year — roughly $4.10 per year at $0.17 per kWh. With a vehicle connected but not charging (idle mode) it draws 4.49 W.
While charging at full current, the charger's own losses were measured at about 20.7 W — roughly 1.08% of its 1.92 kW output — so nearly all the electricity reaches the vehicle.
The vehicle's consumption is far larger than the charger's. As an illustration, an EV driven 12,000 miles a year at about 3.5 miles per kWh needs roughly 3,771 kWh from the outlet including typical charging losses, or about $641 a year at $0.17/kWh. Charging on an off-peak time-of-use rate can reduce that substantially.
