What is the best method to choose best locations for switches of distribution automation?

In my opinion I would go for the direct approach and would like to add when going through the direct approach it should be communicate to the employees in a very positive way so that, employees would be able to take it positive and would be able to fix the issues according to the requirement of company they work for.

Thanks for invitation

this depending on each site and each customer

but there are roles like easy to operate an maintain

place which protect the panels from damage

Study in deep and try with model before implementation

The best location is that where we can do maintenance and replacement easily.
