Was reading some of your previous posts and thought I read you have the Magnetek 6300 Power Distribution panel. If that is what you have then it should be using the ATC type DC fuses...

These are ATC BLADE TYPE fuses


When you refered to glass fuses I was thinking of this style fuse

The ATC Blade fuses is what all the modern Power Distribution Panels uses...
If this is what you have the PD 9260C 60AMP would have been my choice to use as a replacement converter/charger for the bottom compartment of this Power Distribution Unit.

Just my thoughts
