Hi, I have a non class T machinery room that has the ice rink equipment which has Ammonia in it. I reviewed the B52 code for refrigeration and it indicates that it should be class 1 zone 2 hazardous but B52-2013 was issued before the new 2015 code and in new CEC 2015 they have changed the hazardous location codes. So from section 18 of the CEC 2015 it seems that ammonia would be Zone 2 where explosive gas are not likely to occur during normal operation. The reason I am asking is that I know all new equipment should meet code with wiring and ratings but does this apply to control wires as well? I know for gas stations we have intrinsically safe wires but is this required in my case as well?
Thanks,
Thanks,
