Plan the Location

While this charger can be installed as either a plug-in or hardwired, ChargePoint recommends hardwiring for optimal performance.

Before beginning work, check the site for appropriate mounting location and electrical capacity.

  1. Ensure the homeowner has chosen an installation location that allows the charging cable to reach the car's charging port while still providing slack. Mount the charging station on a surface that can support the full weight of the charging station with the cord hanging from it. Follow the steps below to mount on a surface using the supplied screws. Ensure Wi-FiClosed Wireless Fidelity signal is available.

    Outdoor installation requires hardwiring or an outdoor-rated, weather-resistant electrical outlet.

    Technical illustration depicts the procedural step.

    In areas with frequent thunderstorms, add surge protection at the service panel. Ensure all power and ground connections, especially those at the breaker and bus bar, are clean and tight. Remove all oxide from all conductors and terminals before connecting the wiring.
  1. Home Flex must be set to match the rating of the circuit as determined by the available panel capacity.

    Home Flex is a continuous load device. The circuit must be rated for 125% of the maximum load.

    Consult all applicable codes for breaker and wire sizing requirements. The field-wiring terminal is rated to 105 °C (221 °F) and accepts a maximum of 16 mm2 (6 AWGClosed American Wire Gauge) wire.

    A junction box may be required when using breakers rated higher than 50 A.

    In Canada, a plug-in installation is only allowed with a 50 A circuit.

    Technical illustration depicts the procedural step.

  1. For plug-in installation, determine the plug type purchased by the homeowner. It is either an Industrial Grade Outlet (NEMAClosed National Electrical Manufacturers Association 14‑50) or Industrial Grade Outlet (NEMAClosed National Electrical Manufacturers Association 6-50) type plug.

  2. For a hardwired installation, determine if the desired circuit rating requires a hardwired circuit.

  3. Ensure the electrical panel supports a 240 V dedicated circuit with a new, dedicated, non-GFCIClosed Ground-Fault Circuit Interrupter two-pole circuit breaker, in accordance with local codes and ordinances.

    If local codes require a GFCIClosed Ground-Fault Circuit Interrupter breaker for plug-in installation, ChargePoint recommends a hardwire installation. We do not recommend using a GFCIClosed Ground-Fault Circuit Interrupter breaker as the Home Flex has charging circuit interrupting device (CCIDClosed Charge Circuit Interrupting Device) protection. A GFCIClosed Ground-Fault Circuit Interrupter breaker in the panel causes nuisance tripping.

    Technical illustration depicts the procedural step.

  4. For plug-in installations, the outlet should be located 500-600 mm or 0.5 m - 0.6 m (20-26 in) from the ground adjacent to the stud where the charging station will be mounted.

    The input power cable is 0.3 m (12 in) or 300 mm (12 in) long (as per the National Electric Code for EVClosed Electric Vehicle chargers). Ensure the outlet is installed close enough to the stud for the input power cable to plug in.
  5. Follow all applicable codes and ordinances and pull a permit for completing the electrical work as required.

Apply the Electrical Ratings Label

To ensure compliance with inspection standards, apply the correct amperage label to both the charging station and the circuit breaker.

Required Item

ChargePoint Home Flex Amperage Label Sheet (included in box)

  1. Find the sheet titled ChargePointHome Flex Amperage Labels in the packaging. It contains amperage labels in English, French, and Spanish for 16 A, 24 A, 32 A, 40 A, 48 A, and 50 A.

  2. Confirm the amperage setting is configured during installation.

  3. Peel the label that matches the configured amperage from the bottom of the sheet.

  4. Locate the designated label area on the bottom edge of the charging station. Refer to the diagram below for exact placement.


  5. Firmly press the label onto the surface to ensure adhesion.

  6. Place a duplicate label on the breaker that supplies the EVClosed Electric Vehicle charging label in the electrical panel. This helps inspectors verify the amperage configuration.

  7. Ensure the label is clearly visible and legible.
