So I picked up a couple of these at work for free. They are power supply units for CCTV Cameras. Generally pretty low voltage stuff. I figured I could use them as power distribution points for some of my switch machines or split up my track main buss into four different electrical blocks. With the added fuse protection for each section as an added bonus. The question I have is about the fuses that came in them. I'm not too sure if they are more then I need. They are labeled 250V 3A. I was wondering if I should use a lower voltage fuse? I am running an NCE Power Cab. (Suppose I could refer to the manual and see what NCE recommends...) So its late and I'm tired... suggestions? Ideas?
