Common Questions related to installation:
1.) Do I need a professional electrician to install? In many situations local code will require an electrician to install the EV Charger, but it would be possible to install yourself if comfortable working with electricity and your local regulations would allow.
2.) Does Emporia Energy have a list of qualified installers/electricians to help? Not at the moment. We have many customers from around the world and don't have the resources to maintain a list of qualified installers at that scale.
3.) Ground Fault protection? The EV Charger includes built-in ground fault protections in place. Because of this reason, very much recommended to not install a separate GFCI breaker for the charger circuit as that can cause tripping of the GFCI component incorrectly. Details about protections on-device can be found on the Technical Specifications PDF for the EV Charger here: Technical Specs PDF
4.) Power supply wire diameter, AWG? 6 gauge copper wire is recommended for the power supply wiring. Any three wires can work for the two live line connections and ground. If needing a larger wire, a professional electrician will be able to help with specific installation scenarios as needed.
5.) Weather, outdoor installations, waterproof? The EV Charger is classified as a Type 4 NEMA rated enclosure for indoor and outdoor usage. Should work fine in the vast majority of outdoor installation scenarios.
6.) NEMA outlet alignment? The NEMA plug that comes with the EV Charger is 22" long and designed to be flexible enough to flip/wrap into place for any existing NEMA outlet alignment. In its default installation when the NEMA plug is hanging down from the EV Charger, the ground pin is on the bottom of the plug.
7.) Size of cable knockouts on EV Charger? 1 1/4 inch diameter on charger casing. Included conduit fitting is 1" diameter.
8.) Is a neutral line used/required? No, we only need two live lines and ground/earth.
9.) Higher amperage breakers ok? Yes, you can use any breaker size as needed - only lower rated breakers would reduce your available charge rate.
10.) Stranded or solid wire? Solid wire core is certainly recommended, however a professional electrician would be able to confirm whether stranded wire will work for your particular situation.
11.) Can it work on a single phase 240V line? No, needs single-split phase (two lines) @ 120V with 180 degree phase offset to work properly.
12.) Different length charging cables available? Not at the moment, only option is the 22' cable for the time being.
13.) Required wire temperature rating? We require 90C degree rated wiring for the installation.
