I still have some castell master keys. Which apparently don't exist :smiley2::smiley2::smiley2:

Still got mine even though I'm retired. No one will get their hands on them.

No not at all, they are in the hands of someone that KNOWS what they are doing!!

You shouted at me for paralleling two 1600KVA transformers and exceeding the boards maximum fault current.
Two guys working together, one on the each ACB. It will take me longer to type “OPEN” “CLOSE” than it took for the switches to operate. We would have been damned unlucky for a fault to occur in that split second. I did take the precaution of putting the 11KV on to one feeder, that needed my 2[SUP]nd[/SUP] naughty key.

Normal operation A, B, D, E closed C & F open.

Standing instruction is to never potentially over stress equipment, even for switching time, except in exceptional circumstances that are fully risk assessed and appropriate action taken. This would certainly include preventing any access to switch gear etc

how did you know you had exceeded the boards max fault current in your example? You can't just add the fault currents together!
