Socket and fuse are connected to the zero line or FireWire
In other words, the fuse can only be installed on the line of fire.
it will blow, cut off the power to protect the entire circuit safety, so the provisions of the fuse (or fuse) can only be installed On the line of fire, and the zero line is not allowed to install,
The fuse is a protective device, that is, when the circuit is grounded, short circuit and overload situation occurs,
as well as an introduction that does not cause a personal electric shock accident when the electrical leakage is prevented Of the "ground" (usually with a short vertical and three different lengths of the short horizontal composition of the grounding mark), wiring control marked on it.
The socket is a device that can be connected to the power line in parallel with the appliance. Therefore, the terminals on the socket will have a firewire (L) and a neutral line (N),
