By explanation I was asking how this was allowed to happen. Apparently this is not just a circuit or two but a considerable amount of work done by someone who had no clue and certainly had no business doing what they did.

I assume this is a commercial rental space and this "work" was done by the tenant? Interesting that the landlord isn't taking legal action against the tenant after learning what was done to his property and the liability he now has.
