The title says it all, improper electrical installation - unprotected wiring.
Romex wiring, where there is a protective sheathing around various wires that do different things, needs to be installed right. If held with staples, for example, they should not be hammered in too far. If the wiring enters a junction box, it should be clamped. Things like that.
Another consideration is how the wiring is cut in order to service an appliance.
The clamp should be onto the sheathing, with the wiring separated inside a junction box to connect to what it needs to connect to.
Here is the attic side of a bedroom ceiling fan.
First, the insulation was hugely scooped out to create an opening from which to work.
They did provide proper support for the fan, and a good box.
But notice the wiring.
The sheathing was stripped before it gets to the box. This has left the individual wires exposed.
This box was wired to a couple of times. Who knows what all this is to do. It is simply more than just a ceiling fan. But at least one of those jobs did not protect or attach the wiring properly.
The insulation should also be built back up over the installation. Had they done that I would not have seen this!
My recommendation: proper is proper, and improper is improper. There are certain ways things should be done. A professional job pays attention to those proper ways, and might even employ Best Practice ways. But what we see above is not right, and is unprofessional.
