Q: Can I use it in Europe? 220V - 50 cycle

Thank you very much for your attention. We are the manufacturer of the product. The product you inquired about: E4, which is American standard and not applicable to European standard, but our company has E2 product for European standard, but we are sorry that we have not launched it in the European Amazon market.

Q: What is meant by, "zero line", "fire-zero wire", "firewire" and "lack of land"? These are not standard terms.

Sorry. Those terms should be: neutral wire, live wire, the earth wire is missing.

Q: How can it identify which of the 10 circuit breakers on my main panel an outlet has?

To quickly find the circuit breaker corresponding to the socket: please turn off all electronic equipment in use, then press the "RCD TEST" button, and check which circuit breaker is disconnected to confirm the connection between the socket and the circuit breaker .
