Installation Package:

The standard installation package assumes that no changes to your main electrical panel are needed, and your JuiceBox will be installed no more than 6 feet from the panel. Necessary wiring and conduit for the standard installation are included, but the 14-50 receptacle ($10-40) and the breakers ($10-50) are not. You can either supply these items beforehand, or our electrician can sell them to you.

If you choose this option, we will ship the unit to you as fast as we can (production priority). As soon as you have received the unit, please contact the electrician to schedule installation. You may also choose to pick up your unit from our San Carlos facility. Be careful not to schedule installation before your unit arrives - this may result in additional fees! A fully licensed and certified electrician will come out to your home, and Voila! - you have a smart charging station in your driveway/garage/etc!

You will receive an email with the contact information (email, phone number) for your local installer soon after you place your order.

Please note that the final pricing will depend on the site evaluation conducted by our contracted electrician, and an additional transportation fee may apply for locations on the fringes of the installation areas.
