20 Years ago - Back when I was a farmer (This was in Zimbabwe) - I often had to re-set what we called, "D irons" - these were on the Secondary side (400 odd volts) of high level pole mounted transformers - maybe 8m up - and I'd have to push them back in with a PVC pole - just a drain pipe really. This pole mounted transformer used to supply a cotton Gin and if there was an overload - those , "D Irons" used to drop out. There was certainly no fuse wire involved. We'd shut down everything, reset the "fuse" and then turn everything back on - slowly.


Do we have similar here in England?


In 20 years of being here as a spark - I've not come across one but I work around London and not very often on pole mounted transformer supplies.
