Install Optional Internal Panelboard in the Backup Gateway

The Internal Panelboard kit (Tesla P/N 1529623-00-x) may be installed in the Backup Gateway 2 and connected to either the Backup or the Non-Backup terminals by feeding a two pole breaker on the bussing.

  1. Mount the Internal Panelboard into the Backup Gateway using the provided mounting screws (M5x12 hex bolts).
  2. Connect the internal panelboard to either the Backup (2a) or Non-backup (2b) lugs:
    1. Connect the L1 and L2 lugs on the bottom of the Internal Panelboard to the Backup lugs via the provided 105°C-rated CU wire jumpers.
    2. Connect the Non-Backup Lugs to an acceptable branch breaker on the bussing (up to 100 A).

    Note
    The branch breakers are required when connecting the internal panelboard to the Non-Backup lugs to accommodate for wire gauge difference (see Backup Gateway 2 Wiring for wire gauge ranges, and Acceptable Circuit Breakers for acceptable branch circuit breakers).
  3. Once all breakers have been installed, install the breaker hold-down if installing any back-fed or generation breakers on the bussing. Mount the hold-down bracket using the provided (2) M5-0.8x12 Philips head screws.
  4. Place the adhesive circuit label on the deadfront to label circuits.

Design Considerations

The Internal Panelboard is 200 A-rated and supports (6) 1 inch breaker spaces (12 circuits) using acceptable branch circuit breakers up to 125 A maximum (see Acceptable Circuit Breakers for acceptable branch circuit breakers).

The Powerwall+ connection to the Backup Gateway always requires a 50 A circuit breaker. This breaker serves as circuit protection for the Powerwall+. Breaker sizing and installation must comply with the National Electric Code.
