Reply to "The case for fast-acting circuit protection"

Dewey TrogdonOGR Forum Member MEMORIALIZED MEMBER

While powering my 1992 built, 5 track, 15x32, twin shelf airborne operation with 3 pw ZWs I used fuses as protection. Later when I installed TMCC I replaced the ZWs with five 180 POHOs which have fast-acting breakers, added TVS diodes, and removed the fuse block. The fuzzy photo below shows the fuse block and meter panel for the 5 power districts. The center "cartridge" is a piece of copper tubing on the Common circuit(white wire). The fuses were far better protection than the slow-acting {9-10 secs} $4 thermal Potter Brumfield breakers they replaced.
