Powerwall 3 and Backup Gateway 2: panel main breaker magnetothermal only?
Unconfirmed: An Italian user with a 230 V single-phase installation, Powerwall 3 and Backup Gateway 2, with the whole house on backup, asks whether the main breaker in the internal panel can be magnetothermal only. According to his description, the main breaker in the BG2 cuts power to the entire house, while the one in the panel isolates only that panel. The latter is an Eaton FAZ6-C40/2, purely magnetothermal, and the downstream circuits have mostly 30 mA residual current devices.…
- Panel main breaker: Eaton FAZ6-C40/2, magnetothermal only according to the author.
- Downstream circuits use 30 mA RCDs; the BG2 has a 300 mA one whose location is unconfirmed.
🔎 Why it matters: No official confirmation: the question concerns whether the internal panel's main breaker (Eaton FAZ6-C40/2, no RCD) can coexist with 30 mA circuits downstream and a 300 mA RCD inside the BG2 whose position is not confirmed.
📈 Upside: Not applicable.
📉 Risk: Without confirming the position of the 300 mA RCD in the BG2, it is not established which line it protects or whether the panel is covered by any residual current device.
