Shipping is very fast. The neutral is completely dead, unfortunately, it won't work for the generator without an additional disconnector, and thus the point of automating the switching process without human intervention is lost. The advantage is that you can set the necessary overload disconnection. Overall, I am satisfied with the purchase.
