Can the fuse be connected to the zero line?
regulations have this provision! If the fuse installed in the zero line, if the fuse after the use of the state
The possible cause of the voltage below 220V is that the line you are using is the end!

Why the fuse can not be connected to the zero line: because in the electrical safety
