Probably one of the most hazardous parts of my job is running across shady electrical work - like what is in the picture to the left.
Here we have multiple wires in the same junction box, the only problem is that there are only two wire nuts... which means that one of the wire splices was completely unprotected and able to electrocute someone walking by.
When exploring homes on your own, be careful. Never assume that because something has been there for a while that it is safe - especially when it comes to wiring.
