Guys,
Having just gone back into Faults work,
The permutations of having an inadequately marked Industrial installation are only realised during break-downs.
If I am the Line Mechanic that connects the new Distribution Panel up, before I do, I ask if the Installation has been labelled properly, I usually go and check this too, the days of poorly sized fuses and having them blow out our Secondaries, are well upon us.
And try and find the offending fuse!.
No labelling, no connection.
If we can label all of our poles and Air-Break switches and other equipment, spanning an area in miles, not feet or yards, why can't a factory be labelled properly?.
