Device Color Code Systems
Industrial control systems Vs. Power Industry.
There are Standards for common process industry and there are Standards for the Power industry.
They have there differences, what I have observed basically they are:
1- General Industry ( NOT POWER )
RED indication = Stopped, safe condition, the breaker is Opened / or De-Energized.
GREEN indication = Running, Unsafe condition, the breaker is Closed / or Energized.
2- Power Industry (NOT General Industry )
RED indication = Warning, Unsafe condition, the breaker is Closed / or Energized.
GREEN indication = normal, safe condition, the breaker is Opened / or De-Energized.
Both are an industry standard it depends on what industry you are working in.
Does anyone know where I could get documentation that would support my findings?
Thanks,
