Licensed and insured North Atlanta electrician


There are a growing wide range of electric cars and demand for electric vehicle chargers in a home.  Poss Electric Company has certified and trained technicians that install every type of electric vehicle charger.  When purchasing a vehicle, it is equipped with a 120-volt outlet charger known as a Level 1.  The 120-volt cord plugs into a regular household outlet and gives you 4-5 miles of battery life after one hour of charging.  This usually is temporary because that is not typically fast enough for many EV (electric vehicle) owners and so they choose to upgrade by installing a charging station.

Charging stations (also known as Level 2 chargers) use a special 240-volt outlet.  Outlets to power these wall mounted chargers are usually the same as a clothes dryer outlet, oven outlet, or hardwired.  Wall mounted electric car chargers can give a vehicle a full charge between 3-8 hours and require anywhere between 30 – 80 amps.  

In very general terms, higher volts, amps, or kilowatts will mean more electricity that is required.  Buying an electric car charging station can be complicated and you should know the differences between the terms.

  • Volts are like the water pressure.  A Level 2 wall mounted charger will require 240 volts.
  • Amps measure rate of flow of electricity.  Think about it like the volume of water that comes out of a hose at a given point.  Most chargers provide somewhere between 30 – 80 amps of electricity.
  •  Kilowatts measure how much power you get when you multiply the volts (pressure) and the amps (volume).  All Level 2 chargers use 240 volts so you multiply 240 volts by the amps a charger requires is how you would know how many kilowatts are used for one charge.  This will help you calculate the expected electric bill difference per month.

Most electric vehicle charger product specifications use amps as the main measurement to indicate how fast your vehicle will charge.  A simple way to determine your EV charger product is your vehicle will give you about as many hours per hour charged as the amps the charger requires.   If you choose a 50-amp charger, you will get 50 miles per every hour it is plugged into the charger.


We recommend buying a charging station with an output of at least 30 amps.  You may not have the need for 30 amps on your current or first vehicle.  Since the EVs are becoming more in demand every year, it is good to plan ahead for a second electric vehicle or an upgrade in the future.

All electric vehicle owners do not have an enclosed garage to park the car.  If this is the case for your home, you will have to be sure the electric car charger is rated NEMA-3 or NEMA-4 which is suitable for outdoor use.  Poss Electric electricians will make sure the electric installation will be suitable for outdoor use as well and weatherproof.

Georgia Power offers residential customers a $250 rebate for a Level 2 Electric Vehicle Service Equipment (EVSE) installed by December 31, 2021.  Poss Electric Company also offers financing to help make that upgrade possible as soon as possible.

Some panels or electric meter services are already very full as the house stands.  These may require an upgrade of the panel or even the meter service as well before installing the EV charger.  Poss Electric Company are the experts and can determine this.  We will help with your best option to making adequate amperage for your electric vehicle charger upgrade.   This would include all permitting fees and breakers required so call or text today
