I have very often gone into industrial units,supplied 3 phase and single phase outlets,perhaps high bay or fluorescent lights,used differing methods of installing,conduit,pyro, armoured, clipped,whatever was wanted and complied it got installed
What I would not do would be refuse to install because "they may" be used for purposes other than what they are not intended
I have no problem with giving advice and would always do so,but what someone does with their business is their responsibility
Having said that,if I were then to report on a installation that I had fitted and it was being used inappropriately I would also make a unsatisfactory report
My responsibility is not to make decisions on the working environment of other businesses
Just to add,this is my own personal opinion.its not meant to be argumentative,it can be accepted or rejected,that is your own prerogative,what it does not deserve is insult,thanks in advance
