Plug In and Recharge!Plug In and Recharge! When it comes to Residential Electric Car
Charging Stations, Here's What You Should Know.

Protect your new investment and avoid Warranty issues! Always use a trained, certified, licensed professional when installing a car charging station in your home.

Some EV manufacturers and EV charging station manufacturers will void the warranty if their equipment is not installed by a licensed professional. 

Residential Electric Vehicle Charging Stations are Available in Two Levels –
"Level 1" and "Level 2".

There is a Level 3 Charging Station, but that is for use only in commercial applications due to the high voltage that’s required to operate the level 3 charging station.

Here are the Three Charging Levels as specified by the National Electrical Code for Car Chargers:


Voltage (VAC)

Current (Ampe)

Power (kVA)


Standard Outlet

Level 1
Residential Use
120 12 1.44 Single 120V 20 Amp Grounded Outlet
Level 2
Residential Use
208/240 32 6.7/7.7 Single 220V 40 Amp Grounded Power Outlet
Level 3
Commercial & Industrial Use
480 4001 192 Three Phase Three Phase 480V Grounded PowerOutlet

Level 1 (120 Volt AC)
Does not require a charging station!
Uses the on-board charge station that comes with the car. For Level 1 charging, you just have to plug it into a dedicated 120-volt, single phase separate circuit 20-Amp three prong grounded outlet - and the circuit should be installed by a qualified licensed electrician. Although it depends greatly on the vehicle you are charging, it typically takes between 8 to 14 hours to fully charge a vehicle. The charging current is about the same as a standard blow dryer, so it won’t put a burden on your existing electrical service. Obviously, the biggest disadvantage is the length of time it takes to recharge a vehicle. You will need to install a grounded 120 –Volt 20 Amp separate circuit to power the level 1 car charging station.

Level 2 (208-220-230 Volt AC)
All pictures on this page are typical Level 2 charging stations that can be used in your home or in a public space. Level 2 increases the charge power by 5x and decreases the typical full charge time down to 4-8 hours, thus the main advantage for Level 2 Charging is speed. Level 2 charging is the most popular system used by home owners as it offers a quick charge time – half the time of Level 1. You will need to install a dedicated 220-volt single phase grounded separate circuit to power the Level 2 charging station. This circuit is similar to a 220 volt electric dryer circuit.

Level 1 & 2 Installation Process

Typical Installation Takes Only 3-4 Hours & Uses Typical Household Electric Current.
