Thank you very much berkeman that was a great reply it seems to have all the words/concepts i need to be aware of and even a book, thanks again!

I can say for sure that the main thing is to prevent the apparatus from interfering with other processes outside the box and that it should meet the regulations for household products. The current cabinet just barely passed the test for industrial products and although it's purely business to...
