INSTALLING YOUR 240 VOLT OUTLET
The recommended home charging installation for Testa vehicles is a 240 volt NEMA 14-
50 outlet. This outlet is commonly used for electric ranges and large recreational
vehicles. Installed with a 50 amp circuit breaker, this outlet enables a recharge rate of
about 25 miles per hour.
Consult a licensed electrician to review the electrical load of your home prior to
installation. They will design your charging system and obtain a permit for a general
purpose NEMA 14-50 outlet from your local building department. After installation, the
electrician will schedule an inspection to approve the new electrical circuit and design.
This guide provides reference for specifications to install this outlet. Since each
installation is custom to the home, all hardware for the NEMA 14-50 outlet will be
provided by your electrician.
