Installation requirements
1. The capacity of the fuse and melt should meet the design requirements, and the capacity of the protected electrical equipment should be checked to match the melt capacity.
2. The installation position and distance between fuses should facilitate the replacement of the melt.
3. The fuse with a fuse indicator should be installed on the side that is easy to observe.
4. When installing porcelain fuses on a metal base plate, the base should be padded with soft insulation pads.
5. When installing fuses with several specifications, it is necessary to indicate the specifications next to the base.
6. For fuses with wiring markings or with a risk of touching live parts, the power cord should be wired according to the markings.
7. The installation of spiral fuses, the base must not be loose, and the power supply should be connected to the terminal led out of the fuse core.
