Passing the time with plans for stuff that might never happen, but relevant to here is my interest in the selection of a 100A TP & N fuse switch disconnector taking BS88 style fuses. I don't need a switched neutral, but it has to be:
- The "double break" sort where both ends of the fuses are isolated in the off position (as the load has UPS that would make it hazardous to change a fuse if not isolated at load as well as source)
- Lockable in the off position (I would assume all are, but sometimes it is not mentioned?)
