Hello there, All Electrical Engineer fellas, Someday ago, I had been assigned to conduct a building audit of one company in Indonesia. For completing this task, I need all international standard about electrical equipment installation, especially for wiring / cable. Is there anyone who hold / have such a standard ? How long is the lifetime of a power cable ? what is the standard for this ? I've heard that a power cable need / have to be replaced after 20 years of operation, but still I don't know the standard. For the good response and communication towards, Thanks and regards. -Akif E.R.
