Fuses are installed between spring terminals. Fuses rated 8A have a black insulator, 16A have a green insulator. They are arranged in numerical order from left to right.
After pressing the lower or upper terminal, we take out the faulty fuse and install a new fuse of the appropriate rating (see table Electrical circuits protected by fuses).
We snap the lid back into place.
We change the fuses in the additional block in the same way.
