I have not installed yet, but since it uses Panasonic's earth leakage circuit breaker for many years, it will be okay. N line is a little short, I want to install even if I managed to extend it somehow. Because it will be useful when thunder etc. I was asking for the model of BJJ 330325K at any price for price and performance, but it has risen and changed this price so I changed it here. I attach it to an empty room and test, I want to purchase, by the way it is made in Japan.
