Well into the twenty first century, just notice how well modern technologies have advanced. It is so much so the case today that no matter the scale of the industrial or mechanized purpose, everything can be controlled, managed and even repaired from something as remote, portable and lightweight as a laptop computer. Today, if you are a visitor to such premises and you happen to be on site when this happens, you will notice an industrial electronic repair, maintenance and installation technician processing his work from his laptop.
It will, of course, depend on how new the industrial electronic installations are to the premises. Expect otherwise when you are the commercial tenant of an old building at least around thirty years old. No amount of sophistry will work in this case. But expect only the best in skilled circuit board management and repair work. And if you happen to be on site again, this time in an old world scenario, notice the heavy toolbox the electrician or circuit board technician has brought with him.
But it is disheartening to note just how many property owners or managers cut corners by merely tampering with their installations the moment something appears amiss. Usually it is a case of the power going out. Indeed, in many cases it could merely be the case of extension sockets not being inserted correctly to a wall socket. And that is one of the first things that any layman should look out for when carrying out his own inspection.
More importantly, he will never take the electrical law into his own hands. He will always dial up his electrical contractor or circuit board expert to conduct a manual inspection, with or without his laptop.
