Disgusting!
You can tell that is Destroy it Yoursef at its finest there... I can't really tell but it even looks like some of the cables entering the panel at the bottom right just pass through the KO without a connector...

I'd like to see what happens here in Ontario with the implementation of "smartmeters". They record time of use and are remote read BUT also transmit a "loss of supply" signal to the PoCo should the supply to the line side terminals disappear or if the meter is pulled illegally.
Regardless we are still going to be plagued with people that try to do this kind of work themselves and do illegal panel changes HOT!
