The CLIP-TYPE has clips to connect the ferrules or knifeblades of the fuse to the circuit. The
POST-TYPE is an enclosed fuseholder. The center connection of the post type should be connected to the
power source and the outside connector should be connected to the load.
OPEN FUSES can be found by VISUAL INSPECTION, FUSE INDICATORS, or by the use of a
METER. The following SAFETY PRECAUTIONS should be observed when checking a fuse:
Turn the power off and discharge the circuit before removing a FUSE.
Use a fusepuller when you remove a fuse from clip-type fuseholders.
When you check a fuse with a voltmeter, be careful to avoid shocks and short circuits.
When you use an ohmmeter to check fuses with low current ratings, be careful to avoid opening
the fuse by excessive current.
REPLACEMENT FUSES must be of the proper type. Check the technical manual parts list to find
the identification of the proper fuse. If a substitute fuse must be used, the following guidelines should be
followed:
Never use a fuse with a higher current rating, a lower voltage rating, or a slower time delay
rating than the specified fuse.
The best substitution fuse is a fuse with the same current and time delay ratings and a higher
voltage rating.
