Home Installation Help for Level 2 Systems

How do I go about having a charger installed at my home?

A Level 1 charger can simply be plugged into a standard 120 volt outlet. However, if you plan to use a Level 2 charger, which has a faster charging speed, this will need to be plugged into a less common 240 volt outlet.  If you don’t already have one, an electrician will need to wire the 240 volt circuit.  This will include installing a 50-amp circuit breaker in your home’s electric panel and connecting it to a 240 volt NEMA 14-50 outlet or a hard-wired wall-mounted charging station.  The 240 volt outlet should be installed in a location that is both convenient for charging your vehicle and accommodates the length of the EV power cord.  This professional installation can range from only a few hundred to several thousand dollars, depending on the location of the house panel and the charging outlet.

The station will come with a cord and charger head that plugs into your EV.  Since the unit’s default setting is set to low power in standby mode, it is fine to always leave the vehicle plugged in and connected to power (“on”).

Make sure to find certified installers near you that are experienced, licensed electricians that are familiar with and licensed to install a 240 volt system.

Other things to think about when choosing and installing your home charging station:

  • Do I want it hard wired or to plug in to a new or existing 240-volt receptacle?
  • What length of cord will I need to charge reach my EV(s) from the install location? The charging units can be ordered with different cord lengths to suit your needs.
  • Massachusetts also requires that you get a permit. You may need to go to the town’s building division at town hall, fill out a form, etc. Contact us to find out more information about the completing the process where you live. (Most electricians can pull permits for home owners.)
