Paul,
What was the idea behind that?
This happened (so I'm told by an older Faultsman) because a guy up on a farm tried to bypass the unit one day back in the 60's and nearly burned himself to death after he tried to tie the wrong wires together to re-instate the supply to his house, the pole fuse down the road never tripped because of corrosion.
After that, all of the units sported covers over the entire unit, except for a red neon that showed if the unit had tripped.
Our Deputy Chief Fire Officer also confirmed this story, apparently half the house was lost as well.
