Hi I have been a time serverd electrician since I left school,and have been very lucky to have been disciplined in domestic commercial and industrial,my spacialty is control boards and boiler wiring.
I have just been asked by a refrigeration company to start wiring all there cold rooms and freezers installations, so I have wired in a few now, but I must admit its like the first time i wired in a s plan on a domestic boiler system, or commercial boiler, I don't have the first clue what and why..
So I have found myself spending hours trying to research to learn, but your industry seems to be like getting into castle grayskull,
Please could you offer any advise on control courses? that i may attend or any good books that can help me?
