Can a 800A Class L fuse be installed in a 1200A Heavy Duty Safety Switch?
Heavy Duty Safety Switch
Using smaller fuse
Yes, it can. However, only the two inner fuse mounting bolts provided on the 1200A safety switch would be used to mount a 800A frame Class L fuse. If a 1200A frame Class L fuse is used, all four fuse mounting bolts would be used.
