Modifying Fuse Clip Locations
Install 30 and 60 A fuse bases for the proper fuse size and class and
maximum voltage in Size 1 and 2 starter units. The base pan of the
disconnect switch has five sets of mounting holes for this purpose. The lower
fuse base is installed in the proper mounting holes at the factory (see
Figure 67). Additional clips and bases may be required if changing fuse class.
Turn off all power supplying this equipment and follow lockout/tagout
procedures before working on or inside equipment. Always use a properly
rated voltage sensing device to confirm the power is off.
NOTE: For Form II Class C fuse spacing, contact your Schneider Canada
representative.
