\nAs shown in the figure below, the terminal block has the live wire connected on the left and the neutral wire connected on the right. The position of the red line is the creepage distance<\/strong><\/a> of the functional insulation<\/strong><\/a> (the clearance<\/strong><\/a> can also be determined here).
